Might some kid be over the moon, possibly, wearing it? (6)
I believe the answer is:
kimono
'might' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'some kid be over the moon possibly wearing it?' is the wordplay.
'some' says to take the initial letters.
'be over' is a charade indicator (letters next to each other) (in a down clue, some letters go over others).
'possibly' indicates anagramming the letters.
'wearing' indicates putting letters inside.
'it?' becomes 'i' (I can't justify this - if you can you should believe this answer much more).
The first letter of 'kid' is 'k'.
'moon' anagrammed gives 'mono'.
'mono' placed around 'i' is 'imono'.
'k'+'imono'='KIMONO'
Can you help me to learn more?
(Other definitions for kimono that I've seen before include "Eastern robe" , "Japanese wrap" , "Traditional robe in Japan" , "Japanese attireimoni" , "Japanese-style dressing gown or robe" .)
