Where English inherited a word for settled ground, Spanish reached the same destination by way of the hearth — Latin *focus*, the fire that made stone walls livable. The Chinese character 家 makes the boldest claim: a pig sheltered beneath a roof, a family that has decided to stay. Esperanto's *hejmo* lifts the Germanic root and removes its history, a word for home that belongs to no one and therefore to everyone. What unites them is less a concept than a cluster of needs: fire, creature, a patch of ground worth returning to.
Old English *hām* encompassed dwelling, estate, and village — the personal and civic were not yet separated. The narrowing to intimate domestic space is a modern development, preserved in archaic form in English place-names: Birmingham, Fulham, Cheltenham.
Spanish also uses *casa* (from Latin *casa*, hut or shelter) for house and home, but *hogar* carries the warmer, more intimate register — the hearth-home rather than the structure.
A pig sheltered beneath a roof: the domesticated animal as proof of settlement. Where livestock live indoors, a family has committed to staying. Notably, 家 carries both 'home' and 'family' with no distinction — the building and the people inside it are one word, one graph.
Some sinologists argue that 豕 (pig) may have functioned partly as a phonetic loan component in Shang oracle-bone script, not purely semantic. The traditional 'pig-under-roof' reading is vivid and widely taught but may be partly folk etymology.
The derived compound *hejmolando* (homeland) and adjectival *hejma* (domestic, homely) follow standard productive Esperanto morphology. The root was drawn from Germanic by Zamenhof in 1887; his precise source is undocumented.
Every word for home is also a theory about what cannot be replaced.
