### Glyph origin

| | Old Chinese |
| 羥 | *kʰreːn, *kʰreːŋ |
| 俓 | *ŋɡeːn, *ŋɡreːŋ, *keːŋs |
| 牼 | *kʰreːŋ, *ɡreːŋ |
| 硁 |
| 誙 | *kʰreːŋ |
| 娙 | *ŋɡreːŋ, *ɡeːŋ |
| 莖 | *ɡreːŋ, *qreːŋ |
| 痙 | *ɡeŋʔ |
Phono-semantic compound (形聲 / 形声, OC *kʰreːn, *kʰreːŋ): semantic 羊 (“sheep, goat”) + phonetic 巠 (OC *keːŋ) ― a kind of sheep or goat.
For the sense “hydroxy” in organic chemistry, the glyph is a blend of 氫 (“hydrogen”) and 氧 (“oxygen”), using the phonetic components of both characters (巠 and 羊).

### Etymology 1

* 羥基
The pronunciation is a blend of 氫／氢 (qīng, “hydrogen”) and 氧 (yǎng, “oxygen”).
