Chap an angler wouldn't be without (3)
I believe the answer is:
rod
'chap' is the definition.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for rod that I've seen before include "Little boy" , "Staff" , "Fisherman's item" , "Stick; angler" , "Wand - fishing stick" .)
