First Conditional | English Grammar Explanations

When you use First Conditional

Statement — positive or negative sentence

Conditional sentences consist of two parts: if-part and main part.

In First Conditional you should use:

If-part ➔ Present Simple, main part ➔ Future Simple

You can also start a sentence with the main part. But still, you use Future Simple in the main part and Present Simple in if-part.

Main part ➔ Future Simple | if-part ➔ Present Simple

To build Yes/‌No question in First Conditional:

you use tenses the same way you use them in statements (if-part ➔ Present Simple, main part ➔ Future Simple)
in main part you make a question by putting will in the beginning
you can start Yes/‌No question with if-part or with main part

Follow this structure if you want to start Yes/‌No question with main part:

Main part ➔ Will + noun/‌pronoun + verb | if-part ➔ Present Simple

Follow this structure if you want to start Yes/‌No question with if-part:

If-part ➔ Present Simple, main part ➔ will + noun/‌pronoun + verb

Wh-question is a question that starts with a question word (e.g., what, where, when, how, why, how long, etc.)

To build Wh-question in First Conditional:

you use tenses the same way as you use them in statements (if-part ➔ Present Simple, main part ➔ Future Simple)
in main part you make a question by putting Wh question + will + noun/‌pronoun + verb
you can start Wh-question with if-part or with main part

Follow this structure if you want to start Wh-question with main part:

Main part ➔ Wh + will + noun/‌pronoun + verb | if-part ➔ Present Simple

Follow this structure if you want to start Wh-question with if-part:

If-part ➔ Present Simple, main part ➔ Wh + will + noun/‌pronoun + verb
