I believe the answer is:

come

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

'invitation?' is the definition.
(an invitation to come)

I can't explain the rest of the clue.

(Other definitions for come that I've seen before include "Approach" , "Turn up" , "Make a forceful impression" , "Arrive" , "Rude aggressive youth" .)

I've seen this clue in the Evening Standard.
