He fell fetching water - wet top's removed, and coat (6)
I believe the answer is:
jacket
'coat' is the definition.
(jacket is a kind of coat)
'he fell fetching water wet top's removed' is the wordplay.
I cannot really see how this works, but
'he' could be 'jack' and 'jack' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'and' is the link.
Can you help me to learn more?
(Other definitions for jacket that I've seen before include "Book cover" , "Outer skin of a potato" , "Blazer" , "See 1" , "Outer garment or casing" .)
