Local infirm person cut from The Snapper (4)
I believe the answer is:
croc
'snapper' is the definition.
(an animal which 'snaps')
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for croc that I've seen before include "Snapper" , "Fierce beast" , "Large, bony-plated reptile (abbr)" , "Small reptile" , "creature heard to be a vicious one" .)
