Amusing woman’s invitation to stop over November ends in union and marriage (10)
I believe the answer is:
comedienne
'amusing woman's' is the definition.
(female comedian)
'invitation to stop over november ends in union and marriage' is the wordplay.
I cannot really understand how this works, but
'invitation' could be 'come' (an invitation to come) and 'come' is found within the answer.
'stop' could be 'die' (I've seen this in other clues) and 'die' is found in the answer.
'november' could be 'n' (phonetic alphabet: alpha, bravo, charlie etc.) and 'n' is found within the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is found in the answer.
A single letter 'e' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
(Other definitions for comedienne that I've seen before include "Female comedy actor" , "Rivers perhaps" , "stand-up entertainer?" , "Funny female performer" , "Female humorist" .)
