Avoid my first fairground attraction (6)
I believe the answer is:
dodgem
'fairground attraction' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'avoid my first' is the wordplay.
'avoid' becomes 'dodge' (dodge can mean to avoid or evade).
'my first' becomes 'm' (1st letter of 'my').
'dodge'+'m'='DODGEM'
Can you help me to learn more?
(Other definitions for dodgem that I've seen before include "Electric car" , "Small car at funfair for bumping into others" , "Fairground amusement vehicle" , "ride - with 14a" , "Bumper car" .)
