Present in meeting, if tired (4)
I believe the answer is:
gift
'present' is the definition.
('gift' can be a synonym of 'present')
'in meeting if tired' is the wordplay.
'in' says the answer is hidden in the clue.
'GIFT' can be found hidden inside 'meeting if tired'.
(Other definitions for gift that I've seen before include "A present or a natural ability" , "Knack" , "A natural attribute" , "bent" , "flair" .)
