First man’s top half goes into his better half’s skirt (5)
I believe the answer is:
evade
'skirt' is the definition.
(synonyms)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for evade that I've seen before include "Keep away from" , "Shun, escape" , "Escape (esp. by guile)" , "Shirk" , "Illegally escape (taxes)" .)
