Woman not entirely like the others? (5)
I believe the answer is:
norma
'woman' is the definition.
'not entirely like the others?' is the wordplay.
'not entirely' means to remove the last letter.
'like the others?' becomes 'normal'.
'normal' with its final letter removed is 'NORMA'.
(Other definitions for norma that I've seen before include "Operatic heroine" , "She incited Gauls v. Romans (Bellini)" , "Girl" , "Operatic lady round the manor" , "Drawing instrument" .)
