Preacher’s endless babble (5)
I believe the answer is:
rabbi
'preacher's' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'endless babble' is the wordplay.
'endless' means to remove the last letter.
'babble' becomes 'rabbit'.
'rabbit' with its last letter taken off is 'RABBI'.
Can you help me to learn more?
(Other definitions for rabbi that I've seen before include "Jewish minister" , "Hebrew teacher" , "Teacher of Jewish law" , "Jewish law expounder" , "Legal expert" .)
