One vessel capsized in curious Scottish loch — foul play? (5,8)
I believe the answer is:
funny business
'one' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'vessel capsized in curious scottish loch foul play?' is the wordplay.
I cannot really see how this works, but
'vessel' could be 'ss' (prefix in ship names eg SS Great Britain) and 'ss' is found in the answer.
'in' is found in the answer.
'curious' could be 'funny' (synonyms) and 'funny' is present in the answer.
'play?' could be 'use' (play is a kind of use) and 'use' is present in the leftover letters.
A single letter 'b' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for funny business that I've seen before include "Deceptive or disobedient behaviour (of a clown?)" , "Deception" , "Hanky-panky" , "Dubious practice - clown's profession?" , "Jiggery-pokery" .)
