Emphatic do
Definition
Emphatic do, does or did appears in an affirmative clause before a base verb. It strongly confirms the statement, contradicts an assumption or emphasizes that the action is real.
Examples
-
I do understand your concern.
The speaker strongly confirms understanding.
-
She does want to participate.
The emphasis contradicts a possible assumption that she does not want to participate.
-

The past auxiliary emphasizes that the action really happened.
Neutral affirmative vs. emphatic affirmative
I remember the conversation.
The sentence states the fact without special contrast.
I do remember the conversation.
The sentence strongly confirms the fact.
The core event is unchanged. Emphatic do adds the speaker’s insistence, correction or emotional force.
The main verb returns to its base form
Because do / does / did carries tense and agreement, the following lexical verb remains in the base form.
-
He does know the answer.
Does carries third-person agreement, so the main verb is know, not knows.
-
We did try every possible solution.
Did carries past tense, so the main verb is try.
Common mistakes

After did, use the base form rather than a past form.
