Word with tie or fly (3)
I believe the answer is:
rod
'word with tie or fly' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for rod that I've seen before include "something fisherman brings home" , "Cane - shaft" , "A stiff stick" , "An angler's stick" , "Thin straight bar" .)
