To crib and wail during mass (8)
I believe the answer is:
homeward
'to crib' is the definition.
(crib can informally mean someone's home)
'wail during mass' is the wordplay.
'wail' becomes 'mew'.
'during' is an insertion indicator.
'mass' becomes 'hoard'.
'mew' inserted into 'hoard' is 'HOMEWARD'.
'and' is the link.
(Other definitions for homeward that I've seen before include "towards my place" , "Towards one's residence" , "Going to residence" , "back to dwelling" .)
