Real tie breaker in studio (7)
I believe the answer is:
atelier
'studio' is the definition.
(atelier is a kind of studio)
'real tie breaker' is the wordplay.
'real tie' anagrams to 'ATELIER'.
However, I am not sure how the anagram is indicated.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for atelier that I've seen before include "I relate to workshop used by artist" , "Tie earl up in the artist's place" , "Artist's studio (French)" , "Artist's workshop, studio" , "room for artist" .)
