Phrasal verbs are phrases consisting of a verb and another element such as an adverb or a preposition, or both, and has a meaning that differs from the meaning of its separate parts. 
Phrasal verbs are very commonly used in spoken language and presents a challenge for many non-native speakers, especially since many phrasal verbs use the same verb but only change the particle (the preposition or adverb) and then mean something totally different.  Additionally, phrasal verbs, just like normal words, can have more than one meaning.
 
Here is a list of common phrasal verbs used in the workplace as well as related phrasal verbs that can be confused with them:

These sentences show a common error when using 'do/does/did'.

• She didn't liked the present I gave her. ❌
• When did the children made these decorations? ❌
• ​​Does your girlfriend works at the same company? ❌
• ​Does the school accepts transferees? ❌
• My roommate doesn't organizes her makeup on our vanity table. ❌

​You've probably spotted the error in these sentences already. 

Let's review the correct structure:

• ​do/does/did + verb in its BASE form (no -s, -ed or -ing ending)

Whenever you use do, does, or did in a question or negative sentence, the main verb must be in its base form (= the infinitive without "to"; the verb's simplest form, with no -s, -ed, or -ing ending).

Why? The auxiliary verbs do, does, and did already carry the tense, so there is no longer any need to change the main verb.

Quick Fix: 
After do/does/did, always check that the verb is in its base form:

• ❌ She  didn't liked the present I gave her. → ✅ She  didn't like the present I gave her. 
• ❌ When did the children made these decorations? → ✅ When did the children make these decorations? 
• ❌ Does your  girlfriend works at the same company? → ✅ Does your  girlfriend work at the same company? 
• ❌ Does the school accepts transferees? → ✅ Does the school accept transferees?
• ❌ My roommate doesn't organizes her makeup on our vanity table.  → ✅ My roommate doesn't organize her makeup on our vanity table. 

​
Another error to look out for:

Another common mistake is using do, does, or did with modal verbs (can, could, should, must, may, might, will, would). However, modal verbs already act as auxiliary (helping) verbs, so they do not need do/does/did for forming questions or negatives.

Key Rule:
When forming a question with a modal verb, use the modal itself as the auxiliary verb—do/does/did is not needed. For questions using modal verbs, start with the modal verb, followed by the subject and the base verb. 

• ​modal verb (can, should, etc.) + subject + verb in its BASE form

 
Examples:

• ❌ Does she can drive?  →✅ Can she drive?
• ❌ Do you will need loudspeakers?  →✅ Will you need loudspeakers? 
• ❌ Do they should change the background colors?  →✅ Should they change the background colors?
• ❌Does the government should impose stricter regulations for companies selling imported products? →✅  Should the government impose stricter regulations for companies selling imported products?

The key takeaway? If you're using do, does, or did, make sure the main verb stays in its base form. And if you're asking a question with a modal verb, skip do/does/did—the modal itself does the job!

Keep practicing, and soon this will feel completely natural!

When we're asked to give an adjective, we may likely go for words like beautiful, good, bad, or happy. However, adjectives ending in -ing and -ed are just as commonly used in everyday language and they are often a source of confusion among English learners.

For example, we have the pair interesting versus interested, or disappointing versus disappointed, and a very commonly confused pair, bored and boring. Sometimes you might hear somebody say, “I’m boring” but what they actually mean is “I’m bored”. He or she is feeling bored. 

So first, let’s understand the difference between -ing adjectives and -ed adjectives.

• Adjectives ending in –ing such as tiring, amazing, and shocking, are used to talk about the characteristic or quality of a thing, situation or even a person. So if you say “I’m boring” then you are describing yourself as a boring person.
• On the other hand, adjectives ending in –ed such as tired, amazed, and shocked, are used to describe our feelings and emotions, meaning we use –ed adjectives to describe how we feel about a situation, event, person, or thing. So if you say “I’m bored,” for example, with a longer sentence, “I’m bored with this book,” then you mean that you think the book is not interesting to read.

Let’s compare these two side by side before we have more examples:





Let’s have more examples for –ing adjectives:

1. The five-hour hike was really tiring. In this sentence, we are describing the characteristic of an activity, which is hiking, so we will use an –ing adjective.
2. The baby foxes at the animal reservation were cute and amazing. Here, amazing describes the characteristics of the baby foxes.

On the other hand, below are a couple of examples for adjectives ending in –ed. 

1. The fast pace of the hike made most of the participants really tired. The adjective tired is describing how the participants feel.
2. The children were amazed at the sight of the cute baby foxes.  The adjective amazed is describing how the children felt when they saw the baby foxes.

 
Now let’s try to take a look at two sentences with errors regarding adjectives ending in –ing  or –ed.

1. I'm interesting to know how you accomplished that.

• In this sentence, “interesting” is describing how the speaker feels so the correct adjective should be “interested”: I’m interested to know how you accomplished that.”

2. The children feel boring with doing the same activities every day.

• In this sentence, we are describing how the children feel, so the correct adjective should be “bored” instead of “boring”: “The children feel bored with doing the same activities every day.” 

Now that we’ve talked about when to use –ing and –ed adjectives correctly, let’s have more exercises! I will explain the answers to the first two items in this exercise, but you’ll have to answer the rest. Then you can check your answers at the end of this article.

1. The professor was [ annoyed/annoying ] with the students who did not follow her safety instructions.

• What is the adjective describing? Is it the characteristic of the professor, or is it about how the professor felt? It is about how the professor felt towards the students who did not follow safety instructions, so the correct answer is [annoyed]: The professor was [annoyed] with the students who did not follow her safety instructions.

2. My grades were really [ disappointed/disappointing ] last semester so I vowed to work harder this term.

• What is the adjective describing? It’s describing [my grades], not my feelings, so the correct answer is [disappointing]. My grades were really disappointing last semester. 

3. The sudden increase in the number of infections is [ worried/worrying ].
4. She got [ worried/worrying ] when the team did not call her for a few days.
5. Jessie is just not [ interested/interesting] in sci-fi movies. She prefers romantic comedies.
6. It was my first time to experience such a strong earthquake. It was [ terrified/terrifying ].
7. We were all [ surprised/surprising ] when she said she was quitting her job.
8. I had high expectations for this movie and I was not [disappointed/disappointing ].
9. The test was quite difficult. It’s [ amazed/amazing ] that I passed at all.
10. The plot twists in the story are quite [ confused/confusing ].
11. That horror movie shows a lot of [ frightened/ frightening ] scenes.
12. After checking the quality of the products, I was quite [ satisfied/ satisfying ] with them.
13. It’s my first time to travel abroad so I’m really [ excited/exciting ].
14. My friend likes to try exotic and weird foods that some might find [ disgusted/disgusting ].
15. On my second week just staying at home, I started to get [bored/boring].
16. I liked the video but the soundtrack was a bit [ irritated/irritating ].
17. His habit of being late to meetings is really [ annoyed/annoying ].
18. I just had a very [ satisfied/satisfying ] meal at the restaurant you recommended.
19. I think this color combination is very [ pleased/pleasing ] to the eye.
20. She gave incomplete instructions so now I’m a little [ confused/confusing ].
 
That’s the end of our drills on adjectives ending with –ing and –ed. I really hope you found these exercises useful. As you may know, when it comes to correct grammar, you have to train your ear to listen for the correct patterns and word usage so you may want to do the drills a couple of times until you get all the answers correctly.

Today, let us have some sentence correction practice with the following seven sentences: 

1. I've been listening his music for five years.
2. I'm always listening the 80s and 90s music.
3. I've just started to listen Post Malone.
4. He came Marty's house from the future to warn him about something. 
5. There are no masks to export other countries.
6. It's my first time to go a concert.
7. I did not reply her message yet. 

What is the common error among all of them? You would be right if you said that they are missing the preposition 'to'.

Let's have the first one:

1. I've been listening his music for five years.

• Correct: I've been listening to his music for five years.

When it comes to the verb [listen], we use 'to' after it when stating an  object. 

• We listen to someone or something. 
• We listen to music. 
• We listen to a speech.

How about you practice using 'listen to...' by answering the following questions:

• What kind of music do you like listening to? How about the kind of music you DO NOT like listening to?
• What kind of topics or lectures do you like listening to? How about the kind of topics you DO NOT like listening to

The second sentence is still about the verb 'listen':
2. I'm always listening 70s and 80s music.

• Correct: I'm always listening to 70s and 80s music. 

To hammer home this point, let's have one more sentence, still using the word 'listen':
3. I've just started listening Post Malone.

• Correct: I've just started listening to Post Malone. 

The fourth sentence is about a movie that is familiar to many: 
4. He came Marty's house from the future to warn him about something. 

• Correct: He came to Marty's house from the future to warn him about something. 

Regarding the verb come, we use a lot of different prepositions with it (for example: come upon, come with, come by, come for, come across, you get the idea), but we would say 'come to' a place when we mean to arrive at that place or to reach that particular place. 

Let's have a few  examples from the book, 'The Hobbit':

At the beginning of the book, the dwarf Gloin says: "In fact, if it had not been for the sign on the door, I should have been sure we had come to the wrong house."

Bilbo answers: "I am quite sure you have come to the wrong house."

Besides that conversation, here is another sentence from the book that uses 'come to':
"The dwarves then noticed that they had come to the edge of a ring where elf-fires had been." 
(On a side note, and in case you are curious, 'dwarfs' was the standard plural form of the word dwarf. It was J.R.R. Tolkien, the author of the book the Hobbit, who popularized the plural form 'dwarves'.)

Let's move on to the fifth sentence:
​5. There are no masks to export other countries.

• Correct: There are no masks to export to other countries.

Note that a company or a country will export products to another country.
For example: 

• The Philippines exports bananas and mangoes to other countries. 
• Italy exports machinery and metal products, as well as clothing, and luxury goods to different countries around the world.

How about you try using 'export to' by answering the question:

• "What does your country export to other countries?

Please feel free to write your sentences in the comment section.

The next sentence shows a very common mistake that it deserves a video of its own:
6. It's my first time to go a concert.

• Correct: It's my first time to go to a concert.

When talking about a specific place or event, we use the preposition 'to' after verbs of movement such as 'go'. 
As mentioned at the beginning, we also use 'to' to state a destination.  
Examples:  
We go to a shopping mall. 
Someone goes to a wedding. 
People will go to the beach.

To practice this pattern, how about answering this question:

• Where do you like to go when you want to relax?

Example answers would be:

• I go to a park near my house.
• I go to my favorite bar after work.
• I go to this lovely cake shop near my office. 

Keep practicing the structure 'go to a specific place'. 

We have reached our 7th and last sentence for today which is this one:
7. I have not replied her message yet. 

• Correct: I have not replied to her message yet.

We reply or respond to a message, a letter, an email and so on. 
We reply to somebody  or something. This means that we are giving a spoken or written answer.

For example: 
Do you reply or respond to emails as soon as you read them?
I sometimes don't because I tend to think too much. How about you? 

Anyway, we also reply or respond to questions, comments, compliments, and criticisms. Practice by answering the following questions: 

• How do you reply to criticisms? 
• How do you reply to compliments?

All right, that's the end of our sentence correction for today. 
Kindly note that 'to' is not the only preposition that we use with these verbs. There are lots of other prepositions used with these same verbs that would definitely change their meaning. We just have to practice a lot to remember which prepositions are used with which verbs. However, below is a short list of common verbs that are used with 'to'. 

 There are more verbs followed by to than what you can see in this list but these are some of the most common ones. We have seen some of these verbs in the sentence corrections above. Let's briefly run through this list and have simple examples for each one. 

Common verbs followed by the preposition to: 

Go to - I go to the gym every weekend. 
Come to  - Will you come to my birthday party?
Drive to - Let me drive you to the airport.
Journey to - The journey to the Arctic was not easy. 
Point to - He pointed to a house across the street.
Turn to - The lady turned to the man on her right. 
Give to - Please give this letter to his assistant.
Offer to - The manager offered the job to someone who deserved it.
Send to - I will send these flowers to my mother. 
Adapt to - The new employee has adapted to the system quickly.
Add to - Do you have anything to add to my proposal?
Belong to - This jacket belongs to the man who just left.
Consent to - The patients have to consent to this procedure first.
Devote to - He devotes his weekends to gardening. 
Happen to - What happened to your car? 
Lead to - This situation often leads to bad customer experiences.
Listen to - I tried talking to him but he won't listen to me. 
Explain to - The mayor explained the new rules to his staff.
Object to - He objected to being called a traitor. 
React to - Everyone reacted to the news with shock.
Refer to - Please refer to page 90 on your manual. 
Reply to - Please reply to this email on or before Friday.
Respond to - How do you want me to respond to their invitation?
Speak to - May I please speak to the manager?
Talk to - I wanted to talk to the staff before the party.
Say to - She always knows what to say to guests to make them comfortable.
Apologize to - You should apologize to that lady.
Agree to - I did not agree to that plan at all. 
Write to - I was told to write to the manager about this complaint.  

I hope these examples have given you some practice material in terms of using the preposition 'to' when it's needed. Repetition is, of course, key to getting grammar structures right.

​

Which sentence is correct between these two:

• a. Could you tell me your advise?
• b. Could you tell me your advice?

If your answer was b, you got it right! So what's the difference?
Advice /ədˈvɑɪs/ or /ad-vahys/ is a noun that means a recommendation or suggestion about what to do or how to handle a situation. Advice is something that we get from friends, bosses, or lawyers.
Advise /ədˈvɑɪz/ or /ad-vahyz​/ is a verb that means 'to offer an opinion or suggestion' or in other words, to give advice to someone. Advise is something that we do. 

Note that they also sound a little differently. Advice is pronounced with an /s/ sound, as in “ice,” while the verb advise is pronounced  with a /z/ sound like the “-ize” in "size". 

Regarding their different forms:
Advice is uncountable so we would never say 'advices'. We can, however, say pieces of advice. 
Advise, on the other hand, is a regular verb with the usual past, present and future tenses: advised, advise, will advise.

Let's have some examples and common expressions:
1. People run away from her at parties because she's always giving unsolicited advice.  Unsolicited advice refers to advise that is being given without being asked, and is therefore usually unwanted. 
2. I usually avoid telling people that I'm a lawyer because people always try to ask for free legal advice. 
3. His manager advised him to accept the terms being offered in the contract. 
4. Please advise your students to upload requirements through the official website. 
5. That's dangerous. I wouldn't advise you to do that. 

Exercises: Advice or advise?
1. She took the trip against her doctor's __________________. 
2. The team manager should ________________ his team members about the appropriate steps to be taken.
3. I will ask Prof. Norton to ____________ us on how to proceed.
4. I could always count on him for good _____________________.
5. Experts _____________ that hours spent by kids in front of a screen should be limited. 

Characteristic of the English language, we have certain expressions that are paired only with specific words or structures. Below is the list of special expressions that are used with verb-ing or gerunds. Gerunds are verbs ending in -ing, such as running, skydiving, and cycling, that function as nouns. For example, in the sentence "Skydiving is a very expensive hobby", the word skydiving is a noun, not a verb, that refers to an activity and is used as a subject. 

1. 'have' expressions
a. have trouble + verb-ing - I had trouble getting the car to the garage.
b. have difficulty/have a difficult time + verb-ing - The students have difficulty understanding your instructions. 
c. have a problem + verb-ing - She said she was having problems finishing her manuscript. 
d. have a hard time + verb-ing - I told the boss I had a hard time marketing the product to new customers.
e. have fun + verb-ing - Did you have fun taking pictures at the theme park?
f. have a good time + verb-ing - I hope the children are having a good time visiting their cousins. 

2. spend (one's) time + verb-ing expressions
Examples:
He spent the summer catching catfish near the lake. 
Did you spend the whole morning playing video games? 
I spent time at the park just watching the cherry blossoms shed their petals. 

3. waste (one's) time + verb-ing expressions
The professor told us not to waste our time reading this paper. 
Annie wasted no time in preparing for the long trip.
They say the boss often wastes thirty minutes lecturing the group at the start of every meeting.

4. stand, sit or lie + expression of place + verb-ing
I must have stood there looking silly in my costume. 
We would sit on that hillside painting quietly for hours every day. 
He lay low on the grass hoping he wouldn't be seen. 

5. find or catch + noun/pronoun + verb-ing
​They caught him trying to sneak out company property. 
The found the children frolicking dangerously close to the swollen river. 

I came by this sentence today while doing an edit:

• B. F. Skinner's operant conditioning shows the difficulty to change someone's habits by giving negative punishment.

At first glance, there seems to be nothing wrong with this sentence, especially to us non-native speakers of English. However, as you can guess with the title, the error revolves around the word 'difficulty' and that murky concept surrounding gerunds and infinitives. 

You see, the expression [to have difficulty] is one among a special group of expressions that are followed by a verb-ing or a gerund. A gerund is a noun formed from an -ing verb which usually refers to an activity (ex. swimming, hiking), process (ex. aging, weathering) , or state (believing, loving). We then have the structure:

• Subject/Somebody [has difficulty + verb-ing] something.  

Here are examples:  

• The committee had some difficulty deciding the theme of this year's exhibit. 
• Are you having difficulty memorizing your lines?
• I hope you won't have any difficulty settling in to your new school. 

Note though, that we can also use the preposition "in" when using this expression, as in:

• have difficulty (in) doing something

There is no difference in meaning whether we choose to include "in" or to leave it out. Here is a very helpful screenshot from the Longman Dictionary of Contemporary English Online. At the very bottom of the photo, which we have highlighted with the green box, it specifically says that we should not use this expression with a to-infinitive and say [has difficulty to do something]. 

Applying this rule about using gerunds with 'have difficulty', we can then go back to our sentence earlier: ​

• B. F. Skinner's operant conditioning shows the difficulty to change someone's habits by giving negative punishment. 

and improve it by saying:

• B. F. Skinner's operant conditioning shows the difficulty in changing someone's habits by giving negative punishment.

If you are interested in this special group of expressions used with gerunds, find more examples in the following blog post:

• ​Special expressions + verb-ing

Feel free to practice writing your own sentences with the expression [have difficulty + verb-ing in the comments below!

Do you sometimes have trouble with uncountable nouns? Watch our short video below or read through this lesson to learn about uncountable nouns and how to minimize your mistakes when using uncountable nouns.  

 So what are uncountable nouns anyway? The Macmillan Dictionary defines it as: 

• a noun that has no plural form and that usually refers to abstract things such as “advice”, “luck”, and “information”, or to substances such as “milk”, “blood”, and “smoke”.

​The Cambridge Dictionary says that an uncountable noun is: 

• a noun that has one form with no plural and names (or identifies) something that there can be more or less of but that cannot be counted: "Heat" is an uncountable noun.

In other words, uncountable nouns refer to abstract things and substances that we cannot count because they don't have separate elements.

The thing is, it may be easier for an English learner to imagine abstract things as uncountable nouns but there are tricky nouns as well in English that refer to concrete things but are still uncountable, like for example, the noun 'garbage'. You will encounter some nouns like this in our list.

The two definitions of uncountable nouns mentioned above give us an idea of what we need to remember with regard to uncountable nouns, also called non-count nouns or mass nouns. Let us review these points below:

1. Uncountable nouns have NO PLURAL FORM--they are NOT changed into plural form by adding [s]. For instance, we can't say "milks, bloods, smokes, rices, knowledges," and so on.  To quantify uncountable nouns and make them countable, we have to use measure words and expressions of quantity such as a lot of, a little, a piece of, a bag of, a box of, and so on. 
2. Uncountable nouns are used with singular verbs.
3. We cannot use a/an or numbers directly with them. 

Remembering these rules will greatly reduce errors when using uncountable nouns. ​

10 Commonly Confused Uncountable Nouns
Let's us now look at our list of ten commonly confused uncountable nouns. Please note that these ten words are just a few of the many uncountable nouns that cause errors among English learners. For this reason, it is likely that there will be a follow up of this video presenting another list of problematic uncountable nouns. 

1. information - Even when you are talking about boxes and boxes of files and data, we should still say "information" and not "informations." Examples: 

• There was a lot of confusing information on social media before the government made the official announcement.
• The article proposes that we are consuming too much information. 

2. equipment / machinery - Somebody who has a roomful of tools, or even a yardful of tools, has plenty of equipment or machinery, not "equipments" or "machineries". Examples:

• Most of the equipment was donated by private companies.
• Miscellaneous broken equipment is piled in this corner. 
• We keep most of the noisy machinery at the very back of the warehouse. 

3. research - Journals, books, all sorts of academic papers, interviews, experiments -- all of these can be classified as research, but not "researches." Examples:

• Recent research published by two different groups seems to support this theory. 
• She has done a lot of research on this subject  that she has become our resident expert. 

4. trash/garbage/rubbish - We unfortunately generate too much trash that one day, the earth may drown in trash, but when that happens, we would still not refer to it as "trashes", just trash. In American English, 'garbage' and 'trash' are usually used while in British English, 'rubbish' is the more common word to refer to things that are thrown away.  Examples:

• With the landfill no longer usable, the city is trying to figure out a way to deal with its garbage.
• The volunteers collected a lot of trash along the river bank. 

5. evidence - The Oxford English Dictionary notes that "In general English, evidence is always uncountable. However, in academic English, the plural evidences is sometimes used such as in the sentence, 'The cave contained evidences of prehistoric settlement.'"
Since we are mostly talking about everyday English, then we would use evidence as uncountable 99% of the time. 
We would, for example, say pieces of evidence, a lot of evidence, or little evidence. We would never say two evidences or many evidences. Examples:

• Investigators claim to have found an enormous amount of evidence. 
• There was evidence that the package has been tampered with.

6. advice - There is bad advice, terrible advice, as well as prudent advice that we don't want to listen to because we just want to do something our own way. There are people who give unsolicited advice and there are likely more who don't want to be on the receiving end of it. Whichever kind of advice you are getting, remember never to say "advices". 
Examples: 

• That is the best piece of advice I have ever heard from a stranger. 
• Can you give me advice on how to proceed with this huge project? 

7. stuff - What kind of stuff do you collect? Clothes? Vintage toys? Handbags? Art? Memories? There are many things that fall under the definition of stuff, which is a word we use to refer to things, abstract or concrete, without mentioning the thing itself. No matter how much stuff you have, we will always use the singular form "stuff" and not "stuffs".
Examples:

• Where do you want me to put all this stuff? 
• I put your art stuff in the basement because I need to clear this room for our guest. 
• What did you talk about all morning? > Oh, we just talked about sports stuff, that's all. 

8. furniture - You'd think that furniture is a countable noun given that we can count individual pieces of chairs, tables, beds and couches, right? Unfortunately, that's not the case. Think of furniture as a word that collectively refers to all the furnishings in a house and thereby, we cannot say one furniture or even ten "furnitures". 
Examples:

• The apartment was tastefully decorated with minimalist furniture. 
• As he only expects to stay for a year, he is planning to just buy inexpensive furniture. 

9. luggage - Do you travel light or do you usually bring the kitchen sink? However way you like to travel, everything you bring with you will simply be called luggage, never "luggages". 
Examples:

• I had forgotten to bring in my luggage from the driveway. As a result, all three bags got drenched in the rain. 
• The airline can't explain how all my luggage ended up in Hawaii.  

10. jewelry - Just like 'furniture', jewelry seems to refer to individual pieces but whether you are talking about just one ring or a chest full of treasures, both will be referred to simply as jewelry and not "jewelries". By the way, jewelry is the American spelling while the British spell it as 'jewellery'. 
Examples:

• Exquisite pieces of jewelry from the princess's collection will be put on display. 
• Jewelry worth thousands of dollar is missing from the safe.
