I would gamble about bathroom furniture (5)
I believe the answer is:
bidet
'bathroom furniture' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'i would gamble about' is the wordplay.
'i would' becomes 'I'd'.
'gamble' becomes 'bet' (bet is a kind of gamble).
'about' means one lot of letters goes inside another.
'id' going into 'bet' is 'BIDET'.
Can you help me to learn more?
(Other definitions for bidet that I've seen before include "Bathroom basin" , "Washing facility" , "Debit (anag)" , "Low basin for washing private parts" , "Bathroom fitment" .)
