Part of foot alongside claw (5)
I believe the answer is:
talon
'claw' is the definition.
(I know that talon is a type of claw)
'part of foot alongside' is the wordplay.
'part of' says the answer is hidden in the clue.
'TALON' is hidden in the letters of 'foot alongside'.
(Other definitions for talon that I've seen before include "ogee moulding" , "Large claw" , "Tonal (anag.)" , "Eagle claw" , "a gripping one" .)
