Suppress outrageous Latin penned by trio, cutting end (8)
I believe the answer is:
throttle
'suppress' is the definition.
(I've seen this before)
'outrageous latin penned by trio cutting end' is the wordplay.
I cannot quite see how this works, but
'outrageous' could be 'ott' (short for over the top) and 'ott' is located in the answer.
'latin' could be 'l' and 'l' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for throttle that I've seen before include "Strangle; regulator valve" , "one of the controls in a car" , "Check" , "Strangle; fuel controller" , "Choke by pressure on the windpipe" .)
