Silent monk in a light carriage on ski trail out east (8)
I believe the answer is:
trappist
'silent monk' is the definition.
(I've seen this before)
'light carriage on ski trail out east' is the wordplay.
'light carriage' becomes 'trap' (I've seen this in another clue).
'on' says to put letters next to each other.
'ski trail' becomes 'piste' (I've seen this in another clue).
'out' suggests deleting specific letters.
'east' becomes 'e' (abbreviation).
'piste' with 'e' taken out is 'pist'.
'trap'+'pist'='TRAPPIST'
'in a' is the link.
(Other definitions for trappist that I've seen before include "One of an austere and silent order" , "Order (of monks) noted for vow of silence" , "Austere (and silent) monk" , "Member of an order of monks noted for austerity and silence" , "Past trip (anag.)" .)
