Territorial Army loaned gift (6)
I believe the answer is:
talent
'gift' is the definition.
(synonyms)
'territorial army loaned' is the wordplay.
'territorial army' becomes 'ta'.
'loaned' becomes 'lent' ('lend' can be a synonym of 'loan').
'ta'+'lent'='TALENT'
(Other definitions for talent that I've seen before include "Natural endowment" , "ancient coin" , "Genius" , "Special ability, flair" , "Special ability of some kind" .)
