WOUL

It is an aid to the second conditional. It comes from "will", which is an auxiliary of the futureis sometimes used to offer, or invite applications:. I'll give you an example:

Would I eat = I eat.
She Would she sleep = sleep.
Would we run = We would run.

The structure for the Would denial is as follows:

Subject + Would + not + infinitive.

I Would not dance = He does not dance.
I Would not drink = I do not drink.
You'd like you like to study study =

Although the form "would not" is correct is not used when speaking, unless I want to emphasize something.
The most used is "Would"

Now for the question form:

This is its structure:
Would + subject + infinitive?

Would she read? = Does she read?
Would it rain? = ¿Rain?
