Mountaineer's turn of phrase (6)
I believe the answer is:
sherpa
'mountaineer's' is the definition.
(I've seen this before)
'turn of phrase' is the wordplay.
'turn of' indicates an anagram (I've seen 'turn' mean this).
'phrase' is an anagram of 'SHERPA'.
(Other definitions for sherpa that I've seen before include "Asian language" , "one to climb mountains maybe" , "Experienced climber" , "Nepalese mountaineer" , "Phrase for Himalayan mountain climber" .)
