Gift left in market (5)
I believe the answer is:
flair
'gift' is the definition.
(I know that flair is a type of gift)
'left in market' is the wordplay.
'left' becomes 'l' (common abbreviation).
'in' indicates putting letters inside.
'market' becomes 'fair' (both can mean a place where things are sold).
'l' inserted inside 'fair' is 'FLAIR'.
(Other definitions for flair that I've seen before include "Elan; panache" , "Bent" , "Style, talent" , "Taste" , "Intuitive discernment" .)
