Etymologically, the entry records: From Middle English lower case letter v (also written u), from Old English lower case u, from 7th century replacement by lower case u of the Anglo-Saxon Futhorc letter ᚢ (u, ur), derived from Raetic letter u. Before the 1700s, the pointed form v was written… Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is u, spelled U, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.

Definition

  1. 1
    The twenty-first letter of the English alphabet, called u and written in the Latin script.

Etymology

From Middle English lower case letter v (also written u), from Old English lower case u, from 7th century replacement by lower case u of the Anglo-Saxon Futhorc letter ᚢ (u, ur), derived from Raetic letter u. Before the 1700s, the pointed form v was written at the beginning of a word, while a rounded form u was used elsewhere, regardless of sound. So whereas valor and excuse appeared as in modern printing, have and upon were printed haue and vpon. Eventually, in the 1700s, to differentiate between the consonant and vowel sounds, the v form was used to represent the consonant, and u the vowel sound. v then preceded u in the alphabet, but the order has since reversed.

Frequency rank: #819 in English
