Fib teen employed to get advantage (7)
I believe the answer is:
benefit
'advantage' is the definition.
(I've seen this before)
'fib teen employed' is the wordplay.
'employed' indicates anagramming the letters (the same letters employed in a new way).
'fib'+'teen'='fibteen'
'fibteen' with letters rearranged gives 'BENEFIT'.
'to get' is the link.
(Other definitions for benefit that I've seen before include "Good" , "Avail" , "Advantage or profit gained from something" , "Something that aids" , "Charity event" .)
