A Friend asked me how do I know when to use do/does in a question. She said for example, you say "are you tired"? why not say "do you tired"?


Is there any straightforward answer???

Thanks

"tired" is an adjective, it tells us something about how the person feels. So you use "be" (are, is, am)

Or for example:

Is the skirt yellow?

"yellow" is an adjective, too. We learn something about the colour of the skirt.

"do" in questions refers to an action. And it is an auxiliary verb . You use do/does to make questions and negative sentences.

Do you have a bike?

Do you speak English?

Do you think she's good at maths?

Does he like cats?

They don't work.

She doesn't drive.

Important:

"do" can also be the main verb.

What do you do?

They don't do anything to help their mum.

Hope that helps

yes, there is one: never use "do, does" in question with verb to be
in colloquial language (in speech) you can use you "you want to go...?" instead " do you want to go?".

Thank you so much for your answers, but what I meant was is there any rule as such??

So the auxiliar verb "to be" with adjectives, "have" with past participle

Snowflake you said that "do" refers to the action but where is the action in "do you have a bike"?

As the auxiliary verb, do never refers to an action. I'm sure Snowflake wanted to say something in reference to the main verb do, which is a verb of action:

Do (auxiliary verb) you do (main verb) any shopping in the week?
Yes, I do (auxiliary verb).
Yes, I do (main verb) some shopping in the week.
:-D

Thanks, engee30 :) That's really kind of you.

I was looking for a way to explain what I had in mind. Oh, I know what I mean but don't know how to make it clear.:roll:

Engee, I think you got the point. :up:

I wanted to show the difference between the use of "to be" and "to do".

Sorry Anniebee for confusing you.

Have + part participle = Present Perfect

do (as an auxiliary verb) + main verb = Present Simple

"to be" :

See here:

Present Simple

I am from England.
I am a woman.
I am tired.

The same for past simple.

Normally we use the verb to be to show the status or characteristics of something or someone. That's more accurate than only saying "adjectives".

But take a closer look here:

English Grammar - Learn English Grammar - The verb to be


Are there any questions unanswered?
