Stand next to a still (4)
I believe the answer is:
abut
'stand' is the definition.
The definition and answer can be both to do with contact as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'next to a still' is the wordplay.
'next to' says to put letters next to each other.
'still' becomes 'but' (I've seen this in other clues).
'a'+'but' is 'ABUT'.
Can you help me to learn more?
(Other definitions for abut that I've seen before include "Adjoin -- 19 (rev)" , "Join" , "Be next door to" , "Of building or land, end or lean against" , "Touch (side of next building)" .)
