English
fire /faɪər/
Cognate with Ancient Greek πῦρ; both descend from PIE *péh₂wr̥, the root that also yields 'pyre', 'pyro-', and 'pyrex' in modern English.
fire
Spanish names fire after the Roman kitchen: 'fuego' from Latin 'focus,' the hearth — not the wild blaze. English shares its root with Greek πῦρ, keeping ancient fire burning in 'pyro-.' Chinese 火 bypasses sound for shape: four strokes depicting combustion since oracle bones. Esperanto's 'fajro' weaves Germanic thread into Romance grammar, then quietly reinvents 'fajrejo' (fireplace), rhyming with what Latin already knew about taming fire.
Across languages
Español
fuego /ˈfweɣo/
Latin 'focus' originally meant only the domestic hearth or fireplace; the semantic generalisation to fire in the abstract developed in Vulgar Latin. The deeper PIE etymology of 'focus' is unresolved — see caveats.
- focus — Latin: hearth, fireplace; later fire in general (Vulgar Latin)
中文
火 huǒ
火 huǒ
Oracle bone inscriptions (c. 1200 BCE) show two or three upward strokes representing tongues of flame. The modern form — a central rising stroke flanked by two angled ones — is a direct stylisation of that image; the character has not strayed far from its visual origin in three thousand years.
火 is Kangxi radical #86 and appears in hundreds of compounds: 火山 (volcano, lit. fire-mountain), 火车 (train, lit. fire-vehicle), 火花 (spark, lit. fire-flower). Old Chinese *hmɯʔ follows Baxter-Sagart (2014).
- *hmɯʔ (reconstructed) — Old Chinese: fire
- hwaX — Middle Chinese: fire
Esperanto
fajro /ˈfajro/
The root is productive: fajrero (spark; fajr- + -er- diminutive + -o), fajrejo (fireplace; fajr- + -ej- place-of + -o), fajrigi (to ignite; fajr- + -ig- causative + -i). Zamenhof's exact source for 'fajr-' is undocumented; most analysts trace it to the Germanic family (cf. Old High German 'fiur', Old Saxon 'fiur').
- fajro — Esperanto (L. L. Zamenhof): fire; root likely drawn from the Germanic *fūr family
