词源

From Middle English anelen, onelen, from Old English onǣlan (“to burn, ignite, set fire to, consume, heat, enlighten, incite, inflame, inspire, kindle”), from Proto-Germanic *ana (“on”) + Proto-Germanic *ailijaną (“to burn”), from Proto-Indo-European *h₂eydʰ- (“to burn”). The double-N spelling may have arisen by analogy with Latinate verbs like announce, annex, and annul.
The word is related to Old English onāl (“that which is burnt, burning; incense”), Old English āl (“fire, burning”), Icelandic eldur (“fire”), Swedish eld (“fire, flame”), Danish ild (“fire”).
