References: Mostly from Richard Sears'Chinese Etymology site (authorisation), which in turn draws data from various collections of ancient forms of Chinese characters, including: Shuowen Jiezi (small seal), Jinwen Bian (bronze inscriptions), Liushutong (Liushutong characters) and Yinxu Jiaguwen Bian (oracle bone script).

Pictogram (象形) – depiction uncertain. Some propose it depicts a plant's roots underground, possibly as the original form of荄 (OC*kɯː, *krɯː). Others propose it is an animal, similar in origin to豕.

Smith (2011) groups亥 (OC*ɡɯːʔ) in a word-family meaning "root, germ, generative core" along with荄 (OC *kɯ:, “grassroot”) →根 (OC*kɯːn, “root”),核 (OC*ɡrɯːɡ, “germ, kernel”),骸 (OC*ɡrɯː, “(human) bones”), and孩 (OC*ɡɯː, “child”). He suggests the derivation 荄根 "germ, sprout, root (n.)" → 孩 "to sprout" → 亥 "sprouting stage", i.e. "the moon’s first appearance", recalling月芽 lit. "moon sprout" → "crescent moon".

See核 (hé) for further etymology.

Later亥 (hài) and豕 (shǐ, “pig”) graphically converged.

As for亥 (OC*ɡɯːʔ)'s phonological association with the pig. Compare the following:

• Khmerកុរ(kol,“year of the pig”), fromAngkorian Old Khmerkur.
• Proto-Vietic*guːrʔ(“pig; pork”) or*kuːrʔ(“pig; pork”):
  • Vietnamesecúi(“(archaic) pig”)
  • Muongcủi(kuːj³,“pig”)
  • Chutcûl(kûːl,“pig”)
• Thaiกุน(gun,“year of the pig”), a loan from Old Khmer.

Ferlus (2013) notes亥 (OC*ɡɯːʔ) is a possible match to the Austroasiatic root, but there should be a final sonorant in Old Chinese.
