Lily, girl accommodating retired soak (8)
I believe the answer is:
mariposa
'lily' is the definition.
(I've seen this before)
'girl accommodating retired soak' is the wordplay.
'girl' becomes 'maria' ().
'accommodating' is an insertion indicator.
'retired' is a reversal indicator.
'soak' becomes 'sop' (dip food in liquid).
'sop' backwards is 'pos'.
'maria' going around 'pos' is 'MARIPOSA'.
(Other definitions for mariposa that I've seen before include "plant" , "Lily" .)
