Resting place to exist for daughter (3)
I believe the answer is:
bed
'resting place' is the definition.
(where you can sleep or rest)
'exist for daughter' is the wordplay.
'exist' becomes 'be' (synonyms).
'for' means one lot of letters go next to another.
'daughter' becomes 'd' (genealogical abbreviation).
'be'+'d'='BED'
'to' is the link.
(Other definitions for bed that I've seen before include "Couch" , "might be laid here" , "e.g. Four-poster" , "Matrimonial duties" , "Divan" .)
