Dislike old woman with hesitation (5)
I believe the answer is:
odium
'dislike' is the definition.
(I know that odium is a type of disgust)
'old woman with hesitation' is the wordplay.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'woman' becomes 'di' (short for Diana).
'with' means one lot of letters go next to another.
'hesitation' becomes 'um' (um is said in hesitation).
'o'+'di'+'um'='ODIUM'
(Other definitions for odium that I've seen before include "Widespread hatred or disgust felt towards someone" , "Hatred, repugnance" , "Widespread dislike or disgust" , "Wide-spread disgust towards a person or action" , "Offensiveness" .)
