Cross feline with clipped claw (7)
I believe the answer is:
cattalo
'cross' is the definition.
(I've seen this before)
'feline with clipped claw' is the wordplay.
'feline' becomes 'cat' (cat is a kind of feline).
'with' says to put letters next to each other.
'clipped' means to remove the last letter (the word is shortened or clipped).
'claw' becomes 'talon' (talon is a kind of claw).
'talon' with its last letter taken off is 'talo'.
'cat'+'talo'='CATTALO'
(Other definitions for cattalo that I've seen before include "Hybrid animal" , "Cross between buffalo and domestic cow" .)
