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 can't see how one could define the other.
'worn by some eskimo? no' is the wordplay.
'worn' becomes 'on'.
'by' says to put letters next to each other.
'some eskimo?' becomes 'kim' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'no' becomes 'o' (O resembles 0).
'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" .)
