Light taken from attic and left (6)
I believe the answer is:
candle
'light' is the definition.
(candle is a kind of light)
'from attic and left' is the wordplay.
'from' indicates a hidden word.
'CANDLE' can be found hidden inside 'attic and left'.
'taken' acts as a link.
(Other definitions for candle that I've seen before include "Measurement of light" , "Old form of illumination" , "Wax light source" , "Artificial light" , "something wicked" .)
