Creep from Scottish island? (4)
I believe the answer is:
inch
I believe this is a double definition.
'creep' is the first definition.
(I've seen this before)
'scottish island?' is the second definition.
(I've seen this before)
'from' is the link.
(Other definitions for inch that I've seen before include "Subdivision of 14 down" , "Imperial measure" , "Thirty-sixth of yard" , "2.54cm" , "Move slowly and cautiously" .)
