Starts with these components of television set (5)
I believe the answer is:
onset
'starts with these components' is the definition.
The definition suggests an adverb but the answer is not.
'television set' is the wordplay.
'ONSET' is hidden within the letters.
However, I am not sure how this is indicated.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for onset that I've seen before include "Start, beginning" , "origin" , "Start - attack" , "First signs" , "Kick-off" .)
