Phono-semantic compound (形聲 / 形声, OC *kʰoːŋ, *kʰoːŋs) : semantic 穴 (“cave, hole”) + phonetic 工 (OC *koːŋ).

Etymology

From Proto-Sino-Tibetan *(g/k)uŋ (“hole; orifice; inner part”). 孔 (OC *kʰloːŋʔ, “hole”) is probably the endoactive derivation of 空 (OC *kʰoːŋ, “hollow; empty”) (Schuessler, 2007). Cognate with Tibetan ཁུང (khung, “hole”), Jingpho ladi hku (“nostril”), Chepang घाङ् (gʰaŋ, “hole”), Burmese ခေါင်း (hkaung:, “cavity”), Naxi ko³³ (“cave; hole; pit”) (STEDT). See also 坑 (OC *kʰraːŋ, “pit”) and 肛 (OC *kroːŋ, *qʰroːŋ, “anus”), which may or may not be related.
