Merrythought (8)
I believe the answer is:
wishbone
'merrythought' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for wishbone that I've seen before include "Furcula" , "Forked piece of a chicken" , "Part of chicken" , "Bird-part pulled by two people for luck" , "bit of a chicken" .)
