Bone lad broke in locker-room? (6)
I believe the answer is:
ribald
'locker-room?' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'bone lad broke in' is the wordplay.
'bone' becomes 'rib' (rib is a kind of bone).
'broke' indicates an anagram.
'in' means one lot of letters goes inside another.
'lad' with letters rearranged gives 'ald'.
'rib' inserted into 'ald' is 'RIBALD'.
Can you help me to learn more?
(Other definitions for ribald that I've seen before include "Funny, but not nice" , "Scurrilous, bawdy" , "Humorously vulgar" , "Coarsely humorous; scurrilous" , "near the knuckle" .)
