Crossword Genius

Good mimic makes you yawn (4)

Ross

I believe the answer is:

gape

'yawn' is the definition.
(synonyms)

'good mimic' is the wordplay.
'good' becomes 'g' (abbreviation).
'mimic' becomes 'ape' (I've seen this before).
'g'+'ape'='GAPE'

'makes you' acts as a link.

(Other definitions for gape that I've seen before include "Failure to meet" , "Appear amazed" , "Gawp" , "Stare stupidly" , "Stare with open mouth in wonder" .)

I've seen this clue in The Sunday Times.
