Is it correct to write does imply or implies?

Both "does imply" and "implies" can be grammatically correct, but they are used in slightly different contexts:

"Does imply" is used in the present simple tense, usually in questions or negative statements.

* Example: *Does this statement imply that you agree with me?*

* Example: *This document does not imply any legal obligation.*

"Implies" is used in the present simple tense for general statements or in the third person singular for statements about a specific subject.

* Example: *This research implies that further investigation is needed.*

* Example: *The professor implies that the exam will be difficult.*

So, the correct usage depends on the sentence structure and context.
