Promise broken by Paul's wife in budgie smugglers, perhaps? (8)
I believe the answer is:
swimwear
'budgie smugglers perhaps?' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'promise broken by paul's wife' is the wordplay.
'promise' becomes 'swear' (as in swearing something is true).
'broken by' indicates putting letters inside (inserted letters break into the word).
'paul's' becomes 'I'm' (where the crossword setter is 'Paul').
'wife' becomes 'w' (abbreviation).
'im'+'w'='imw'
'swear' going around 'imw' is 'SWIMWEAR'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for swimwear that I've seen before include "Trunks and bikinis" , "Poolside clothing" , "Bathing costumes" , "Beach attire" .)
