It's used for televising the boss with ten more (6)
I believe the answer is:
studio
'it's used for televising' is the definition.
I can't judge whether this definition defines the answer.
'boss with ten more' is the wordplay.
'boss with' becomes 'stud' (both can mean a metal decoration. I am not sure about the 'with' bit.).
'ten' becomes 'IO' (IO resembles s0).
'more' is a charade indicator (letters next to each other) (some letters added to the previous ones).
'stud'+'io'='STUDIO'
'the' acts as a link.
Can you help me to learn more?
(Other definitions for studio that I've seen before include "Artist's workplace - where films are made" , "Where one may paint" , "Artist's work room" , "Film producer" , "Where an artist works" .)
