Adverbials are words that we use to give more information about a verb. They can be one word (angrily, here) or phrases (at home, in a few hours) and often say how, where, when or how often something happens or is done, though they can also have other uses.

Read clear grammar explanations and example sentences to help you understand how adverbials are used. Then, put your grammar knowledge into practice by doing the exercises.

* He do it very well.
*He does it very well.

What is the correct one?


Hello Tharindu,

'He does it very well' is correct.  'He' is a third-person form, and so 'does' is needed.

I can't understand. I don't understand. which is the correct one????


Would is used much times. But i can't understand how use would. Some teachers say would is past of should. But would is used more than that.


Hello Tharindu,

You're right that would is used in many different ways. I'd suggest you read our will or would page for more information.

As for your other question (above), both sentences are correct, but they mean slightly different things: "I can't understand" implies that you have made an effort to understand something, but still don't understand it.

Hello :),
Can you tell me deferent between "good" and "well".

Hello Anak,

'Good' is an adjective which is used, for example, to describe nouns:

He did a good job.

'Well' is an adverb which is used, for example, to describe verbs:

He worked well.

I hope that clarifies it for you.

Can you tell me the difference between "during" and "while"? as I am confused of using them.
example:I have met him during my vacations, and I have met him while on my vacations.
thanks in advance.

Hello chenlyfen60,

The meaning is the same but, as your examples show, their use is slightly different. 'During' is followed by a noun:

duing the holiday

during the weeked

during my lesson

'While' is followed by a sentence or an -ing form:

while I was working

while I was at work

while reading a book

while travelling home

I hope that clarifies it for you.

Best wishes,

Hi chenlyfen60, I am a student like you in this forum, therefore take a second advice after reading my answer.

My answer-

The word 'during' is a preposition and 'while' is a conjunction

(conjunction= words which usually join sentences).
(preposition= the words/terms which tell about the position of one thing to another)

your sentence 'I have met him during my vacations' is perfect, but if you want to use while then say ' while being on my vacations' OR 'while I was on my vacations' which is better.
