Display the commercial inside in a situation away from light (6)
I believe the answer is:
'a situation away from light' is the definition.
I can't judge whether this defines the answer.
'display the commercial inside' is the wordplay.
'display' becomes 'show' (synonyms).
'the commercial' becomes 'ad' (abbreviation for advertisement).
'inside' is an insertion indicator.
'show' enclosing 'ad' is 'SHADOW'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for shadow that I've seen before include "Follow; partial darkness" , "Secret follower" , "Hint, remnant; follow secretly" , "Dark area, weak remnant (of something)" , "This opposition cabinet parallels the government" .)
