Clothing for Tokyo's nobility largely unused (3)
I believe the answer is:
obi
'clothing' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'tokyo's nobility largely unused' is the wordplay.
'OBI' is hidden within the letters.
But, I'm not sure how this is indicated.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for obi that I've seen before include "Material band" , "Martial arts sash" , "sash from Tokyo" , "Caribbean's charming" , "Spells" .)
