構想
こうそう · kousou · JLPT N1 · noun
plan
📐 構 (build, frame) + 想 (thought) = a thought you build into a plan
構 means to construct or frame, and 想 means thought or idea. Together they describe assembling loose thoughts into a structured plan or concept.
想 — heart 心 + 相 (xiāng, phonetic)
想 is a semantic-phonetic compound. The heart radical 心 at the bottom carries the meaning, since classical Chinese located thought and feeling in the heart. The top component 相 (xiāng) supplies the sound, and over time the character settled into the senses 'to think,' 'to want,' and 'to miss.'
