Bet on vessel (4)
I believe the answer is:
punt
This clue could be a double definition.
'bet on' is the first definition.
(synonyms)
'vessel' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
Can you help me to learn more?
(Other definitions for punt that I've seen before include "gambling" , "Riverboat" , "Flat boat for Irish money" , "Kick -- bet -- boat" , "pound in Ireland" .)
