anneal

== English == === Etymology 1 === 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”). ==== Pronunciation ==== IPA(key): /əˈniːl/ Rhymes: -iːl Hyphenation: an‧neal ==== Verb ==== anneal (third-person singular simple present anneals, present participle annealing, simple past and past participle annealed) (metallurgy) To subject to great heat and then (often slow) cooling, and sometimes reheating and further cooling, for the purpose of rendering less brittle; to temper; to toughen.
