Light put on a cat that was sent the wrong way (3,6)
I believe the answer is:
led astray
'sent the wrong way' is the definition.
The answer and definition can be both to do with communicating as well as being past participle verbs.
Maybe there's a link between them I don't understand?
'light put on a cat' is the wordplay.
'light' becomes 'led' (light-emitting diode).
'put on' is a charade indicator (letters next to each other).
'cat' becomes 'stray' (stray is a kind of cat).
'led'+'a'+'stray'='LED ASTRAY'
'that was' is the link.
Can you help me to learn more?
(Other definitions for led astray that I've seen before include "taught bad habits" , "Persuaded to take wrong course" , "Brought or lured away from the proper path" , "Caused to go in the wrong direction" , "Deceived" .)
