都心
としん · toshin · JLPT N2 · noun
heart
🏙️ 都 = metropolis, 心 = heart, so 都心 = the heart of the metropolis (downtown)
都 means capital or metropolis, and 心 means heart or center. Together they name the central business district of a big city.
都 — 者 (phonetic) + 邑/阝 (city radical)
A semantic-phonetic compound. The right-side 阝 (a reduced form of 邑 'city, settlement') gives the meaning, while 者 supplies the sound. Originally it referred to a capital or major city, and later extended to mean 'all' or 'even' when read dōu.
心 — pictograph of a heart with chambers and aorta
心 is a pictograph showing a stylized heart, with strokes representing the organ's chambers and the aorta at the top. Originally meaning the physical heart, it broadened to cover mind, feelings, and intentions, since ancient Chinese thought located thinking and emotion in the heart.
