A short distance from Winchester (6)
I believe the answer is:
inches
'a short distance' is the definition.
(an inch is a small measurement)
'from winchester' is the wordplay.
'from' says the answer is hidden in the clue.
'INCHES' is hidden in the letters of 'winchester'.
(Other definitions for inches that I've seen before include "Niches (anag.)" , "Small islands" , "Moves slowly and cautiously" , "Twelve of them in a foot" , "Moves away; units of measurement" .)
