Live as daughter, prosperously (5)
I believe the answer is:
dwell
'live' is the definition.
(to live/dwell somewhere)
'daughter prosperously' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'prosperously' becomes 'well' (synonyms).
'd'+'well'='DWELL'
'as' acts as a link.
(Other definitions for dwell that I've seen before include "Inhabit" , "Harp" , "Reside - linger" , "Exist (within)" , "Hang out" .)
