Chinese

simp. and trad.		硅

Glyph origin 1

Chemical element
Si
Previous: 鋁／铝 (lǚ) (Al)
Next: 磷 (lín) (P)

Phono-semantic compound (形聲／形声) : semantic 石 (“stone”) + phonetic 圭 (guī).

Etymology

An orthographic borrowing from Japanese 硅(けい)素(そ) (keiso) (Wu, 2010); pronunciation from its phonetic part 圭 (guī) (ibid.), in turn from Dutch keiaarde (“silicon”). The usage of 矽 (xī) is dated in Mainland China as it is homophonous to 硒 (xī) "selenium" and 錫／锡 (xī) "tin". In Taiwan, these three words are not homophonous.

1933 work 化學命名原則 says:

Silicon舊譯一作硅，一作矽，硅由日名珪素孳演而成，因爲固體，故改王旁爲石；於義既無可取，不如用諧聲之矽。 [Classical Chinese, trad.]

Silicon旧译一作硅，一作矽，硅由日名珪素孳演而成，因为固体，故改王旁为石；于义既无可取，不如用谐声之矽。 [Classical Chinese, simp.]
