Went on water in vessel with huge dictionary! (6)
I believe the answer is:
'went on water' is the definition.
The answer and definition can be both to do with motion as well as being past participle verbs.
Perhaps you can see a link between them that I don't see?
'vessel with huge dictionary' is the wordplay.
'vessel' becomes 'can' (type of container).
'with' says to put letters next to each other.
'huge dictionary' becomes 'oed' (Oxford English Dictionary. I am not sure about the 'huge' bit.).
'in' acts as a link.
Can you help me to learn more?
(Another definition for canoed that I've seen is " Travelled by a small boat".)
