oneとは 意味・読み方・使い方

別の表記

• wone (obsolete)
• (Arabic numeral): 1 (see for numerical forms in other scripts)
• (Roman numeral): I

語源 1

From 中期英語 oon, on, oan, an, from 古期英語 ān (“one”), from Proto-West Germanic *ain, from Proto-Germanic *ainaz (“one”), from Proto-Indo-European *h₁óynos (“single, one”).

Cognate with Scots ae, ane, wan, yin (“one”); North Frisian ån (“one”); Saterland Frisian aan (“one”); West Frisian ien (“one”); Dutch een, één (“one”); German Low German een; German ein, eins (“one”); Danish en (“one”); Swedish en (“one”); Norwegian Nynorsk ein (“one”), Icelandic einn (“one”); Latin ūnus (“one”) (Old Latin oinos); Russian оди́н (odín), Spanish uno. Doublet of a, an, and Uno.

The use as an indefinite personal pronoun may have been influenced by unrelated French on, although the Germanic languages widely use cognates for the same sense (usually in non-subject function, but also in subject function, e.g. Luxembourgish een).

Verb form from 中期英語 onen.

発音

Around the 14th century, in southwest and western England, the word began to be pronounced with an initial /w/ (compare e.g. woak, Middle English wocke, a dialectal form of oak), and the spellings won and wone began to be found alongside on, one; the /w/, though initially nonstandard, had become the norm by the 18th century. In alone, atone, and only, as well as in the dialectal form un, 'un (and in none and no), the older pronunciations without /w/ are preserved, while once shows the same /w/.
