Live adequately under daughter's roof (5)
I believe the answer is:
dwell
'live' is the definition.
(I know that live can be written as dwell)
'adequately under daughter's roof' is the wordplay.
'adequately' becomes 'well' (both can mean to a sufficient extent).
'under' says to put letters next to each other.
'roof' suggests taking the first letters (the letter at the top of the word).
The first letter of 'daughters' is 'd'.
'well' after 'd' is 'DWELL'.
(Other definitions for dwell that I've seen before include "Remain" , "Harp" , "Exist (within)" , "Focus attention (on)" , "Inhabit" .)
