A Scotsman has a ball in Lithuania eating prime seafood (9)
I believe the answer is:
langouste
'seafood' is the definition.
(langouste is a kind of seafood)
'a scotsman has a ball in lithuania eating prime' is the wordplay.
I cannot really understand how this works, but
'a' could be 'an' and 'an' is found in the answer.
'ball' could be 'o' (O looks like a ball) and 'o' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for langouste that I've seen before include "something to eat" , "One in the sea" , "Spiny lobster without large claws" , "thing to devour!" , "It may be eaten roasted" .)
