Toy with head removed that spins (4)
I believe the answer is:
eddy
'toy with head removed that spins' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'toy with head removed' is the wordplay.
'toy' becomes 'teddy' (teddy is a kind of toy).
'with head removed' means to remove the first letter.
'teddy' with its initial letter taken away is 'EDDY'.
Can you help me to learn more?
(Other definitions for eddy that I've seen before include "Counter-current" , "Swirl, whirl" , "Ripple" , "Water circulating" , "Turner at sea" .)
