Amphibian Buddhist monk caught in power-driven polisher (10)
I believe the answer is:
salamander
'amphibian' is the definition.
(salamander is a kind of amphibian)
'buddhist monk caught in power-driven polisher' is the wordplay.
'buddhist monk' becomes 'lama' (as in the Dalai Lama).
'caught in' means one lot of letters goes inside another.
'power-driven polisher' becomes 'sander' (machine used to sand things).
'lama' going within 'sander' is 'SALAMANDER'.
(Other definitions for salamander that I've seen before include "Newt-like amphibian" , "Fiery spirit" , "portable stove" , "poker" , "amphibious creature" .)
