Gift article left in a tent (6)
I believe the answer is:
talent
'gift' is the definition.
('talent' can be a synonym of 'gift')
'article left in a tent' is the wordplay.
'article' becomes 'a' (indefinite article).
'left' becomes 'l' (common abbreviation).
'in' means one lot of letters goes inside another.
'a'+'l'='al'
'al' inserted within 'tent' is 'TALENT'.
(Other definitions for talent that I've seen before include "Dull means claw" , "Natural skill or flair" , "Innate aptitude" , "Genius" , "Special ability, may be natural" .)
