Religious teacher given time to chatter (6)
I believe the answer is:
rabbit
'chatter' is the definition.
(both can mean to talk excessively)
'religious teacher given time' is the wordplay.
'religious teacher' becomes 'rabbi' (Jewish teacher).
'given' says to put letters next to each other.
'time' becomes 't' (abbreviation).
'rabbi'+'t'='RABBIT'
'to' is the link.
(Other definitions for rabbit that I've seen before include "Talk at length" , "Poor performer" , "Updike's Harry Angstrom" , "Waffle" , "one found in the tail" .)
