### Glyph origin

Historical forms of the character 坑 :
| Warring States | Shuowen Jiezi (compiled in Han) |
| Qin slip script | Small seal script |
| | Old Chinese |
| 笐 | *kaːŋ, *ɡaːŋs |
| 亢 | *kaːŋ, *kʰaːŋs |
| 牨 | *kaːŋ |
| 苀 | *kaːŋ, *ɡaːŋ |

| 忼 | *kʰaːŋʔ, *qʰaːŋ |

| 秔 | *kraːŋ |
| 坑 | *kʰraːŋ |
| 劥 | *kʰraːŋ |
In its current form, a phono-semantic compound (形聲 / 形声, OC *kʰraːŋ) : phonetic 亢 (OC *kaːŋ, *kʰaːŋs) + semantic 土 (“soil”). Early forms appear to be 阬.

### Etymology 1

Possibly related to 空 (OC *kʰoːŋ, *kʰoːŋs, “empty; space; air”), though the function of the *-r- in the Old Chinese reconstruction is unclear and its presence thus problematic (STEDT).
