At home, Dave somehow gets daughter occupied (7)
I believe the answer is:
invaded
'occupied' is the definition.
('invade' can be a synonym of 'occupy')
'at home dave somehow gets daughter' is the wordplay.
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'somehow' is an anagram indicator.
'gets' means one lot of letters goes inside another (gets can mean captures or absorbs).
'daughter' becomes 'd' (genealogical abbreviation).
'dave' is an anagram of 'vaed'.
'vaed' going around 'd' is 'vaded'.
'in'+'vaded'='INVADED'
(Other definitions for invaded that I've seen before include "Overran" , "Entered intrusively" , "Stormed" , "Occupied" , "Encroached, intruded" .)
