Wreckage of canoe found floating here (5)
I believe the answer is:
ocean
'floating here' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'wreckage of canoe' is the wordplay.
'wreckage of' indicates anagramming the letters (I've seen this in other clues).
'canoe' anagrammed gives 'OCEAN'.
'found' acts as a link.
Can you help me to learn more?
(Other definitions for ocean that I've seen before include "Salt water expanse" , "Pacific, perhaps" , "eg Indian, Pacific" , "Main" , "Vast sea" .)
