English grammar: Basic question formation

What this grammar point covers

Basic question formation in English means how to make simple questions using words like 'do', 'does', 'is', 'are', 'can', etc.

When to use it

Use these forms to ask for information, to check facts, or to get yes/no answers in English.

Key forms

• Do/Does + subject + base verb? (Do you like coffee?)
• Is/Are + subject + ...? (Is she your friend?)
• Can + subject + base verb? (Can he swim?)
• Wh- question word + auxiliary + subject + base verb? (Where do you live?)

Examples

Tips

• Remember to use 'do' or 'does' for most present simple questions.
• For 'he', 'she', 'it', use 'does' instead of 'do'.
• Don't forget to change the word order: the auxiliary verb comes before the subject.

Exceptions and edge cases

• For the verb 'to be', do not use 'do/does'. Start the question with 'Is' or 'Are'.
• Some modal verbs (like 'can', 'should') also do not use 'do/does'.
