Fish lake getting knickers etc. (8)
I believe the answer is:
lingerie
'knickers etc' is the definition.
I can't judge whether this defines the answer.
'fish lake getting' is the wordplay.
'fish' becomes 'ling' (ling is a kind of fish).
'lake' becomes 'erie' (Lake Erie is one of the Canadian/US 'Great Lakes').
'getting' says to put letters next to each other.
'ling'+'erie'='LINGERIE'
Can you help me to learn more?
(Other definitions for lingerie that I've seen before include "flimsy stuff" , "frillies" , "stockings, say?" , "CLOTHING" , "One from W Atlantic island group" .)
