Heartless modern flirts (4)
I believe the answer is:
toys
'flirts' is the definition.
(I know this)
I cannot 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 "Sports" , "Fiddles" , "Plays (with something), not seriously" , "Chihuahuas?" , "Things that provide amusement" .)
