Woman's hesitation about narrow ring (7)
I believe the answer is:
eleanor
'woman's' is the definition.
'hesitation about narrow ring' is the wordplay.
'hesitation' becomes 'er' (sound made while hesitating - um, er).
'about' indicates putting letters inside.
'narrow' becomes 'lean'.
'ring' becomes 'O' (letter resembling a ring).
'lean'+'o'='leano'
'er' going around 'leano' is 'ELEANOR'.
(Other definitions for eleanor that I've seen before include "Miss Rigby" , "girl" , "woman" , "Wife of F. D. Roosevelt" , "Queen from Aquitaine" .)
