Time to go around something under the bridge? (5)
I believe the answer is:
troll
'something under the bridge?' is the definition.
I can't tell whether this definition defines the answer.
'time to go' is the wordplay.
'time' becomes 't' (abbreviation).
'to go' becomes 'roll' (rolling is a kind of going).
't'+'roll'='TROLL'
'around' acts as a link.
Can you help me to learn more?
(Other definitions for troll that I've seen before include "Fish by pulling a hook, line and sinker" , "Scandinavian dwarf or giant" , "who's stirring on-line" , "Bad fairy (giant or dwarf)" , "Creature from Norse mythology" .)
