Duck around ring in a child's vehicle (7)
I believe the answer is:
scooter
'a child's vehicle' is the definition.
(I've seen this in another clue)
'duck around ring in' is the wordplay.
'duck' becomes 'scoter' (scoter is a kind of duck).
'around ring' becomes 'o' (letter resembling a ring. I am not sure about the 'around' bit.).
'in' means one lot of letters goes inside another.
'scoter' placed around 'o' is 'SCOOTER'.
Can you help me to learn more?
(Other definitions for scooter that I've seen before include "one makes off quickly" , "Two-wheeled motor vehicle" , "Light motorcycle" , "it may need physical boost" , "Child's two-wheeled vehicle" .)
