Hollow biblical translation entertained by Canterbury? (6)
I believe the answer is:
cavity
'hollow' is the definition.
(cavity is a kind of hollow)
'biblical translation entertained by canterbury?' is the wordplay.
'biblical translation' becomes 'av' (abbreviation for Authorised Version).
'entertained by' is an insertion indicator (I've seen this in other clues).
'canterbury?' becomes 'city' (Canterbury is an example).
'av' put into 'city' is 'CAVITY'.
(Other definitions for cavity that I've seen before include "Hole, gap" , "Internal void" , "A hollow within a solid, say tooth" , "A hole could mean work for the dentist" , "Decayed part of tooth" .)
