The may, however, sometimes be pronounced in unusually "careful" or "pedantic" speech; in such cases, it is often mistakenly inserted after long vowels even when there is no phonemic . Yaqui Similarly in Yaqui, an indigenous language of northern Mexico, intervocalic or syllable-final is often dropped with lengthening of the previous vowel: pariseo becomes , sewaro becomes . Lacid Lacid, whose exonyms in various literature include Lashi, Lachik, Lechi, and Leqi, is a Tibeto-Burman language spoken by the Lacid people. There are various reports of their population from 30,000 to 60,000 people. Most are in Myanmar, but there are also small groups in China and Thailand. Noftz (2017) reports finding an example of a rhotic alveolar fricative in Lacid while he was doing phonological research at Payap University, in Thailand, in 2015. He was not able to continue his research and expressed the need for further examination of the segment to verify his results. It is postulated that the segment is a remnant of the rhotic fricative in Proto-Tibeto-Burman. Kurdish The Shekaki accent of the Kurmanji dialect of Kurdish is non-rhotic: the postvocalic flap "r" is not pronounced unlike the trill "R". When "r" is omitted, compensatory lengthening of the preceding vowel takes place: sar ("cold") is pronounced /saː/ torr ("net") is pronounced /tor/ (with a trilled r) Shekaki retains morphological syllables, instead of phonological syllables, in non-rhotic pronunciation. Berber languages Syllable-final is lost in many varieties of Rif Berber and is lengthened before to , and and become diphthongs like inEnglish or German. However, a distinct phoneme from earlier exists and does not undergo the same development.
