L-vocalizationL-vocalization, in linguistics, is a process by which a lateral approximant sound such as l, or, perhaps more often, velarized ɫ, is replaced by a vowel or a semivowel. There are two types of l-vocalization: A labiovelar approximant, velar approximant, or back vowel: [ɫ] > [w] or [ɰ] > [u] or [ɯ] A front vowel or palatal approximant: [l] > [j] > [i] Examples of L-vocalization can be found in many West Germanic languages, including English, Scots, Dutch, and some German dialects.
Old English phonologyOld English phonology is necessarily somewhat speculative since Old English is preserved only as a written language. Nevertheless, there is a very large corpus of the language, and the orthography apparently indicates phonological alternations quite faithfully, so it is not difficult to draw certain conclusions about the nature of Old English phonology. Old English had a distinction between short and long (doubled) consonants, at least between vowels (as seen in sunne "sun" and sunu "son", stellan "to put" and stelan "to steal"), and a distinction between short vowels and long vowels in stressed syllables.
