incendio
/inˈθendjo/ · B1 · noun · m
fire
🔥 incendio ≈ incendiary: same Latin root, incendere = to set on fire
From Latin incendium, from incendere (to set alight). English kept the root in incendiary and incense, which is burned. The -cend- core is related to candle, so the word family is all about things that burn.
