Sexual advances defile graduate (4)
I believe the answer is:
pass
I believe this clue is a triple definition!
'sexual advances' is the first definition.
'pass' can be an answer for 'advances' (as in 'to make a pass'). I'm not sure about the 'sexual' bit.
'defile' is the second definition.
(thesaurus)
'graduate' is the third definition.
(pass the exam)
Can you help me to learn more?
(Other definitions for pass that I've seen before include "change" , "Exceed; go by" , "Blow over" , "Decline to answer" , "degree?" .)
