Rattles royalist by calling out compulsive liar (4)
I believe the answer is:
toys
'rattles' is the definition.
Although both the answer and definition are verbs in their -s form, I cannot see how one could define the other.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for toys that I've seen before include "Things that provide amusement" , "Chihuahuas?" , "Matters of no importance" , "dolls, for example" , "Film" .)
