What mother-in-law is to Hitler woman! (7)
I believe the answer is:
anagram
'what mother-in-law is to hitler' is the definition.
I can't tell whether this defines the answer.
'woman' is the wordplay.
I cannot quite see how this works, but
'woman' could be 'ana' and 'ana' is present in the answer.
The remaining letters 'gram' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for anagram that I've seen before include "Word created from other word" , "Type of word puzzle" , ""Diagnose" is one of "San Diego"" , "characters on the move" , "Argue the point" .)
