Template:English vowel development

This table describes the main changes from Late Proto-Indo-European and Proto-Germanic up through Old English, Middle English and Modern English. It focuses on the Old English and Middle English changes leading to the modern forms. Other tables are also available to cover specific areas in more detail:


 * A table specifically covering the vowel history from Proto-Germanic to Old English.
 * A table specifically covering the vowel history from Old English to Modern English, providing particular detail about the Modern English developments.
 * A table specifically focusing on the history of Middle English diphthongs, covering the period from Old English to Modern English.

This table only describes the changes in accented syllables. Vowel changes in unaccented syllables were very different and much more extensive. In general:
 * 1) In Old English, long vowels were reduced to short vowels (and sometimes deleted entirely) and short vowels were very often deleted. All remaining vowels were reduced to only the vowels, and , and sometimes . ( also sometimes appears as a variant of unstressed .)
 * 2) In Middle English, almost all unstressed vowels were reduced to ; then, final was dropped. The main exception is Old English -iġ, which becomes Modern English -y.
 * 3) Unstressed vowels in Modern English other than those spelled are due either to compounds or to borrowed words (especially from Latin and Old French).

NOTE: The Old English words in this table are given in their Anglian form, since this is the form that underlies Modern English. However, standard Old English was based on the West Saxon dialect, and when the two dialects differ, the West Saxon form is indicated with a WS in parentheses following the Anglian form.

NOTE: In this table, abbreviations are used as follows:

1"Pre-Germanic" in this context refers to a post-PIE language that maintains PIE phonology but with morphological adjustments made as necessary to account for the Proto-Germanic form. Reconstructions are only given for solidly reconstructible Proto-Indo-European roots.

1A + separates the sounds that produced the Proto-Germanic vowels in question from the sounds that formed the conditioning environment. The notation C* means a sequence of zero or more consonants.

2I-umlaut refers to a sound change that took place around 500 AD with pervasive effects on English vowels. Specifically, vowels were fronted or raised whenever an or  followed in the next syllable. Nearly every vowel was affected. Affected vocabulary is shown in a different color.

3 PIE n̥ and n̥H became Proto-Germanic un; similarly for m̥, l̥ and r̥. K refers to either of the PIE sounds ḱ or k, which fell together in Proto-Germanic and the other centum languages; or to any of the nine PIE velars when followed directly by a voiceless consonant (especially t). H refers to any laryngeal sound. The ogonek (e.g. ą, ǭ) indicates a nasal vowel. Long vowels are noted with a macron (e.g. ē, ō). Extralong vowels are noted with a circumflex (e.g. ô).

4 The origins of Proto-Germanic ē are somewhat in dispute.
