As worn by some Eskimo? No! (6)
I believe the answer is:
kimono
'as' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'worn by some eskimo? no' is the wordplay.
'worn' becomes 'on' (as in having clothes on).
'by' says to put letters next to each other.
'some eskimo?' becomes 'kim' (I can't explain this - if you can you should believe this answer much more).
'no' becomes 'O' (resembles 0 - 'no' can mean 'zero').
'on' put after 'kim' is 'kimon'.
'kimon'+'o'='KIMONO'
Can you help me to learn more?
(Other definitions for kimono that I've seen before include "Japanese style of robe or gown" , "Japanese attireimoni" , "Japanese clobber" , "Oriental gown" , "Japanese-style dressing gown or robe" .)
