Worn playthings? (4)
I believe the answer is:
tops
This might be a double definition.
'worn' is the first definition.
Both the definition and answer are adjectives. Perhaps there's an association between them I don't understand?
'playthings?' is the second definition.
(top is a kind of plaything)
Can you help me to learn more?
(Other definitions for tops that I've seen before include "Excellent" , "Caps; outdoes" , "Goes beyond" , "The best" , "Big tents" .)
