Some meagre entitlement for the inexperienced (5)
I believe the answer is:
green
'the inexperienced' is the definition.
(I've seen this before)
'some meagre entitlement for' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'GREEN' is hidden within 'meagre entitlement for'.
(Other definitions for green that I've seen before include "member of political party" , "The colour of immaturity" , "one may be putting on" , "The colour of growing grass" , "Naive; colour" .)
