Remains while the female hides inside (5)
I believe the answer is:
ashes
'remains' is the definition.
(thesaurus)
'while the female hides inside' is the wordplay.
'while' becomes 'as'.
'the female hides inside' becomes 'hes' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'as'+'hes'='ASHES'
Can you help me to learn more?
(Other definitions for ashes that I've seen before include "Test-match trophy" , "''... to ..., dust to dust'' (burial service)" , "International competition" , "Remains of the Yule logs?" , "Cricketing trophy - remains" .)
