These cats I sculpted for art theory (10)
I believe the answer is:
aesthetics
'art theory' is the definition.
The answer and definition can be both related to thinking as well as being singular nouns.
Maybe there's a link between them I don't understand?
'these cats i sculpted' is the wordplay.
'sculpted' indicates an anagram.
'these'+'cats'+'i'='thesecatsi'
'thesecatsi' anagrammed gives 'AESTHETICS'.
'for' is the link.
Can you help me to learn more?
(Other definitions for aesthetics that I've seen before include "Principles of taste & art" , "Philosophy of the fine arts" .)
