Warring States	Shuowen Jiezi (compiled in Han)		Liushutong (compiled in Ming)
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, from Proto-Sino-Tibetan *m/s-k(w)a-j (“mouth; opening; spread; door; face; jaw”). Cognate with 戶 (OC *ɡʷaːʔ, “door”), Tibetan ཁ (kha, “mouth”), Tibetan སྒོ (sgo, “door”).

The word is possibly a colloquial variant of 闓 (OC *ŋ̊ʰɯːlʔ, *ŋ̊ʰɯːls) (Schuessler, 2007). Proto-Mien *kʰu̯ɔiᴬ (“to open”) (whence Iu Mien kʰɔi¹) and Thai ไข (kǎi) are Chinese loans (Ratliff, 2010).
