She might change her husband? (5)
I believe the answer is:
edith
'she' is the definition.
(I've seen this before)
'change her husband?' is the wordplay.
I cannot really understand how this works, but
'change' could be 'edit' (edit can mean to change or alter) and 'edit' is found within the answer.
'husband?' could be 'h' (abbreviation) and 'h' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'might' acts as a link.
Can you help me to learn more?
(Other definitions for edith that I've seen before include "- - Piaf, singer" , "Dame ----- Evans (1888-1976), stage and screen actress" , "- Cavell, nurse executed in 1915" , "Female name" , "- Cavell, WW 1 heroine" .)
