Hire a pal to come round and be motherly (8)
I believe the answer is:
parental
'be motherly' is the definition.
(thesaurus)
'hire a pal to come round' is the wordplay.
'hire' becomes 'rent' (synonyms).
'to come round' means one lot of letters goes inside another.
'rent'+'a'='renta'
'renta' placed into 'pal' is 'PARENTAL'.
'and' acts as a link.
(Other definitions for parental that I've seen before include "of father, perhaps" , "of some older relatives" , "Relating to mother and father" , "like mum and dad" , "of old man and woman" .)
