語源
英語の原文（Wiktionary）
From Middle English aren, from Old English (Anglian) earun, earon (“are”, plural). Possibly reinforced by the Old Norse plural forms in er-, this displaced the alternative forms Old English sind and bēoþ. In the second person singular it displaced archaic art. Further etymology controversial: * The English forms, as well as the Old Swedish forms in ær-, could reflect Proto-Germanic preterite-present *ōr ~ *arum, from Proto-Indo-European *h₃e-h₃ór-h₂e (“I have risen”, perfect). * Since they are not the expected outcomes of the Proto-Germanic forms of *wesaną (“to be”) in *iz-, they would have to be irregular alterations.
