Loudly made fun of Sherpa? (5)
I believe the answer is:
guide
'sherpa?' is the definition.
(I've seen this in another clue)
'loudly made fun of' is the wordplay.
'loudly' shows a homophone (sound like) (when spoken - not silently).
'made fun of' becomes 'guyed' ('guy' can be a synonym of 'make fun of').
'guyed' is a homophone of 'GUIDE'.
(Other definitions for guide that I've seen before include "Lead, direct" , "Direct, influence" , "Pilot" , "Direct; show the way to" , "Book for tourists" .)
