Plate 1 The Chinese character 心: a curved stroke ending in a hook, with three dots round it

Xīn 心

The character for ‘heart’ and ‘mind’, and radical 61 of the 214 Kangxi radicals, under which characters for thought and feeling are filed.

Chinese radicals. Also called chinese character for heart, heart radical, heart radical 忄, kangxi radical 61, radical 61, vertical heart radical, 心, 忄.

Meaning

Unihan defines 心 as ‘heart; mind, intelligence; soul’, and also as the fifth lunar mansion, whose determinative star is Antares. On the left of a character it stands upright as 忄, three strokes, ‘heart; radical number 61’, as in 情 ‘feeling, sentiment, emotion’; at the foot it keeps its full form, as in 想 ‘think, speculate, plan, consider’. Mandarin reads it xīn; Japanese, kokoro.

Origin and history

Wieger read the old form as a drawing of the organ: “On the top, the pericardium opened; in the middle, the organ; at the bottom, a summary delineation of the aorta.” He noted “modern abbreviations” of it, and called it the radical “of characters relating to the feelings”.

Upright beside, full underneath

情 is 心 (as 忄) with eight strokes more and 想 is 心 with nine, so a radical dictionary finds both under radical 61, though the heart stands on the left of one and lies under the other.
