Volunteers with only daughter having claws (7)
I believe the answer is:
taloned
'having claws' is the definition.
(I've seen this before)
'volunteers with only daughter' is the wordplay.
'volunteers' becomes 'TA' (abbreviation for Territorial Army).
'with' is a charade indicator (letters next to each other).
'only' becomes 'lone' (synonyms).
'daughter' becomes 'd' (genealogical abbreviation).
'ta'+'lone'+'d'='TALONED'
(Other definitions for taloned that I've seen before include "Hawk being so" , "with pincers" , "with nippers?" , "Note lad (anag) - with claws" , "Nailed" .)
