Late Middle English: from Latin incendiarius, from incendium 'conflagration', from incendere 'set fire to'.

  • incandescent from late 18th century:

    This comes via French, from Latin incandescere ‘glow’, based on candidus ‘white’ ( see candidate). The prefix in- here intensifies the meaning. The incense (Middle English) that you burn comes from the related candere ‘to glow’, while the word meaning ‘to inflame with anger’ comes from the related incendere ‘set fire to’ also found in incendiary (Late Middle English).
