Emphatic do, all and the thing

Use emphatic auxiliaries and focused noun clauses to correct assumptions or foreground a key point.

When do we use it?

Apply do-support and focused all or thing clauses naturally in formal and spoken contexts.

Form

Use do/does/did + base verb for emphasis and all/the thing + clause + be for focus.

• I do understand.
• She did warn us.
• All I wanted was an answer.

Key contrast

At C1, grammar choices shape emphasis, stance, information flow and register as well as basic correctness.

Common mistakes

• I do understood. → I do understand.
• All I wanted it was help. → All I wanted was help.

Remember

Use emphatic auxiliaries and focused noun clauses to correct assumptions or foreground a key point.
