Endless waffle from teacher (5)
I believe the answer is:
rabbi
I believe this is a double definition.
'endless waffle' is the first definition.
(I've seen this before)
'teacher' is the second definition.
(Jewish teacher)
'from' is the link.
(Other definitions for rabbi that I've seen before include "Hebrew teacher" , "Teacher of Jewish law" , "Religious leader of Jewish congregation" , "Jewish learned man" , "Minister of a synagogue" .)
