Chess problem I ruminate about (9)
I believe the answer is:
miniature
'chess problem' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'i ruminate about' is the wordplay.
'about' indicates anagramming the letters.
'i'+'ruminate'='iruminate'
'iruminate' anagrammed gives 'MINIATURE'.
Can you help me to learn more?
(Other definitions for miniature that I've seen before include "Putting game" , "Small-scale version" , "Diminutive" , "Of a much smaller size than usual" , "illuminated letter" .)
