Teacher cutting chatter short (5)
I believe the answer is:
rabbi
'teacher' is the definition.
(I've seen this in another clue)
'chatter short' is the wordplay.
'chatter' becomes 'rabbit' (both can mean to talk excessively).
'short' means to remove the last letter.
'rabbit' with its final letter taken away is 'RABBI'.
'cutting' acts as a link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for rabbi that I've seen before include "Legal expert" , "Religious person" , "Hebrew scholar" , "Jewish law expounder" , "Leader of worshippers" .)
