Women’s group left with drunk around dusk (8)
I believe the answer is:
twilight
'dusk' is the definition.
(I know that dusk can be written as twilight)
'women's group left with drunk around' is the wordplay.
'women's group' becomes 'wi' (Women's Institute).
'left' becomes 'L' (common abbreviation).
'with' says to put letters next to each other.
'drunk' becomes 'tight' (I've seen this in other clues).
'around' is an insertion indicator.
'wi'+'l'='wil'
'wil' placed within 'tight' is 'TWILIGHT'.
(Other definitions for twilight that I've seen before include "Vampire book" , "Evening glow" , "semi-darkness" , "Period post-sunset" , "Period of illumination when sun is just below horizon" .)
