Some four in all are found in the gents (6)
I believe the answer is:
urinal
'found in the gents' is the definition.
I can't tell whether this defines the answer.
'some four in all' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'URINAL' can be found hidden inside 'four in all'.
'are' acts as a link.
Can you help me to learn more?
(Other definitions for urinal that I've seen before include "public convenience" , "Sanitary fitting" , "waste disposal unit" .)
