I am looking at a definition for 心中 that reads: "noun: in mind".
To me, the English phrase "in mind", I don't really think of it as a noun, what does it mean to be a noun that means "in mind", does it refer to the state of something so much as it is "in mind"? If so, wouldn't there be a much better word to describe that?
How does the character 心 "mind" relate to its partner, 中 (in, among, centre, etc) to form this compound two-part character that stands for a "noun meaning 'in mind'"?
