Wife to moan about another like her (5)
I believe the answer is:
woman
'wife' is the definition.
(I've seen this in another clue)
'moan about another like her' is the wordplay.
I cannot quite see how this works, but
an anagram of 'moan' is 'oman' which is located in the answer.
A single letter 'w' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for woman that I've seen before include "person not going on stag-night" , "Mature female" , "Adult female" , "Lady" , "With 1a [OLD], one's rather timid" .)
