Lord to leave with daughter (3)
I believe the answer is:
god
'lord' is the definition.
(thesaurus)
'leave with daughter' is the wordplay.
'leave' becomes 'go'.
'with' is a charade indicator (letters next to each other).
'daughter' becomes 'd'.
'go'+'d'='GOD'
'to' is the link.
(Other definitions for god that I've seen before include "Pan perhaps" , "Worshipped figure" , "Creator of the universe" , "Mars or Mercury, say" , "Being upstairs" .)
