Is there convenience for them in Regent Street? (5)
I believe the answer is:
gents
'is there convenience for them' is the definition.
I can't tell whether this defines the answer.
'in regent street?' is the wordplay.
'in' says the answer is hidden in the clue.
'GENTS' is hidden within 'regent street'.
Can you help me to learn more?
(Other definitions for gents that I've seen before include "Male loos" , "Men (colloq.)" , "toilet" , "Public convenience" .)
