Twist or pass Round One (4)
I believe the answer is:
coil
'twist' is the definition.
(to coil is to twist or wind round)
'pass round one' is the wordplay.
'pass' becomes 'col' (col is a term for a mountain pass).
'round' means one lot of letters goes inside another.
'one' becomes 'i' (Roman numeral).
'col' enclosing 'i' is 'COIL'.
'or' acts as a link.
(Other definitions for coil that I've seen before include "Wound length (of rope)" , "Wind into rings or spiral" , "Helix" , "Twist" , "Wind (wire, rope, etc)" .)
