Gathered across boat, fish caught for Billingsgate? (11)
I believe the answer is:
marketplace
'billingsgate?' is the definition.
(Billingsgate Market in London)
'gathered across boat fish caught' is the wordplay.
I cannot really see how this works, but
'across' could be 'ac' (I've seen this in other clues) and 'ac' is found in the answer.
'boat' could be 'ark' (ark is a kind of boat) and 'ark' is found within the answer.
'gathered' could be 'met' ('meet' can be a synonym of 'gather') and 'met' is located in the leftover letters.
This may be the basis of the clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for marketplace that I've seen before include "The world of buying and selling" , "World of commercial transactions" , "Commercial arena" , "Scene of buying and selling" .)
