A champion plaything (3)
I believe the answer is:
top
This clue could be a double definition.
'a champion' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'plaything' is the second definition.
(top is a kind of plaything)
Can you help me to learn more?
(Other definitions for top that I've seen before include "The circus tent can be a big one" , "Peak; beat" , "Toy; uppermost point" , "cap and > sweater" , "jumper, say?" .)
