Causes male to abandon slippers, leaving nothing in them? (9)
I believe the answer is:
occasions
'causes male' is the definition.
'occasions' can be an answer for 'causes' (occasion can mean to cause or bring about). I'm not certain of the 'male' bit.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for occasions that I've seen before include "Special times or events" , "Social events" , "Causes to happen" , "Celebrations" .)
