Make a false impression (5)

I believe the answer is:

forge

I'm a little stuck... Click here to teach me more about this clue!

'make' is the definition.
(I know that forge is a more specific form of the action make)

I don't understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for forge that I've seen before include "Form by heating and hammering" , "Shape by heating and hammering, as smith does" , "Create; counterfeit" , "Ironworks" , "Smith's workplace" .)

I've seen this clue in The Globe and Mail.
