yin

Etymology

It is borrowed from Chinese 陰 (yīn, “shade, feminine; the moon”),^[2][3][4][1] which Merriam-Webster glosses as the dark, feminine principle.^[5] Wiktionary notes that the character was first used of shaded places, as of a mountain or a house.^[1] The American Heritage Dictionary traces the Mandarin word through Middle Chinese to Proto-Sino-Tibetan *rum (“shade”).^[6]

Earliest recorded meaning

In Chinese philosophy, the feminine or negative principle of the two opposing forces of the universe: 1671, in John Ogilby's translation of the Atlas Chinensis of Olfert Dapper and others.^[2][5][7]

Semantic evolution

The word came into English as a term of Chinese cosmology, always paired with yang, its masculine and positive opposite.^[3][7][5] Yin is the principle of darkness, cold, wetness and passivity, which combines with yang to produce all things.^[5][2] The combined form yin-yang is recorded from 1850,^[7] and the use as an adjective, "that represents yin; feminine", from the mid 20th century.^[3][8]
