Would the light be a trick? (6)
I believe the answer is:
beacon
'would the light' is the definition.
I can't judge whether this definition defines the answer.
'be a trick?' is the wordplay.
'trick?' becomes 'con' (a con is a fraud or trick).
'be'+'a'+'con'='BEACON'
Can you help me to learn more?
(Other definitions for beacon that I've seen before include "Guiding light?" , "Signal fire - transmitter" , "Warning light on a high point" , "Shining light (on top of a hill?)" , "Raised signal fire or light" .)
