Historical forms of the character開
Warring States	Shuowen Jiezi (compiled inHan)		Liushutong (compiled inMing)
Qin slip script	Ancient script	Small seal script	Transcribed ancient scripts

Ideogrammic compound (會意 /会意): 門(“door”) + 一(“latch and/or wooden pole that shuts a door”) + 廾(“a pair of hands”) — a pair of hands opening a latched door.一 and廾 are combined into开 since the Small Seal script; however, in the conservative variant𨵑, the two hands and the latch are well visible.

Compare闢. See also關, in which the door is kept shut by two wooden poles.

According to STEDT, fromProto-Sino-Tibetan*m/s-k(w)a-j(“mouth; opening; spread; door; face; jaw”). Cognate with戶 (OC*ɡʷaːʔ, “door”),Tibetanཁ(kha,“mouth”),Tibetanསྒོ(sgo,“door”).

The word is possibly a colloquial variant of闓 (OC*ŋ̊ʰɯːlʔ, *ŋ̊ʰɯːls) (Schuessler, 2007).Proto-Mien*kʰu̯ɔiᴬ(“to open”) (whenceIu Mienkʰɔi¹) andThaiไข(kǎi) are Chinese loans (Ratliff, 2010).
