Generosity and passion are absent in girl (7)
I believe the answer is:
largess
'generosity' is the definition.
(largess is a kind of generosity)
'passion are absent in girl' is the wordplay.
'passion' becomes 'rage' (synonyms).
'are' becomes 'a' (short for 'are', historical unit of measurement).
'absent' suggests deleting specific letters.
'in' is an insertion indicator.
'girl' becomes 'lass' (lass can informally mean a girl).
'rage' with 'a' taken away is 'rge'.
'rge' inserted into 'lass' is 'LARGESS'.
'and' is the link.
(Other definitions for largess that I've seen before include "Generosity" , "Bounty" .)
