Loud crowd threatening a seafaring group (8)
I believe the answer is:
flotilla
'seafaring group' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'loud crowd threatening a' is the wordplay.
'loud' becomes 'f' (short for forte - 'loud' in music).
'crowd' becomes 'lot' (a lot of people).
'threatening' becomes 'ill'.
'f'+'lot'+'ill'+'a'='FLOTILLA'
Can you help me to learn more?
(Other definitions for flotilla that I've seen before include "set of boats" , "number of vessels" , "A lot of craft" , "set of vessels" , "Group of boats or small warships" .)
