L-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. L-vocalization has occurred, since Early Modern English, in certain -al- and -ol- sequences before coronal or velar consonants, or at the end of a word or morpheme. In those sequences, /al/ became /awl/ and diphthonged to /ɑul/, while /ɔl/ became /ɔwl/ and diphthonged to /ɔul/. At the end of a word or morpheme, it produced all, ball, call, control, droll, extol, fall, gall, hall, knoll, mall, pall, poll, roll, scroll, small, squall, stall, stroll, swollen, tall, thrall, toll, troll and wall. The word shall did not follow this trend, and remains /ˈʃæl/ today. Before coronal consonants, it produced Alderney, alter, bald, balderdash, bold, cold, false, falter, fold, gold, halt, hold, malt, molten, mould/mold, old, palsy, salt, shoulder (earlier sholder), smolder, told, wald, Walter and wold (in the sense of "tract of land"). As with shall, the word shalt did not follow the trend and remains /ˈʃælt/ today. Before /k/, it produced balk, caulk/calk, chalk, Dundalk, falcon, folk, Polk, stalk, talk, walk and yolk. Words like fault and vault did not undergo L-vocalization but rather L-restoration. They had previously been L-vocalized independently in Old French and lacked the /l/ in Middle English but had it restored by Early Modern English. The word falcon existed simultaneously as homonyms fauco(u)n and falcon in Middle English. The word moult/molt never originally had /l/ to begin with and instead derived from Middle English mout and related etymologically to mutate; the /l/ joined the word intrusively.
