SonorantIn phonetics and phonology, a sonorant or resonant is a speech sound that is produced with continuous, non-turbulent airflow in the vocal tract; these are the manners of articulation that are most often voiced in the world's languages. Vowels are sonorants, as are semivowels like [j] and [w], nasal consonants like [m] and [n], and liquid consonants like [l] and [r]. This set of sounds contrasts with the obstruents (stops, affricates and fricatives).
ApproximantApproximants are speech sounds that involve the articulators approaching each other but not narrowly enough nor with enough articulatory precision to create turbulent airflow. Therefore, approximants fall between fricatives, which do produce a turbulent airstream, and vowels, which produce no turbulence. This class is composed of sounds like [ɹ] (as in rest) and semivowels like [j] and [w] (as in yes and west, respectively), as well as lateral approximants like [l] (as in less).
Lateral consonantA lateral is a consonant in which the airstream proceeds along one or both of the sides of the tongue, but it is blocked by the tongue from going through the middle of the mouth. An example of a lateral consonant is the English L, as in Larry. Lateral consonants contrast with central consonants, in which the airstream flows through the center of the mouth. For the most common laterals, the tip of the tongue makes contact with the upper teeth (see dental consonant) or the upper gum (see alveolar consonant), but there are many other possible places for laterals to be made.
PhonemeIn phonology and linguistics, a phoneme (ˈfoʊniːm) is a unit of phone that can distinguish one word from another in a particular language. For example, in most dialects of English, with the notable exception of the West Midlands and the north-west of England, the sound patterns sɪn (sin) and sɪŋ (sing) are two separate words that are distinguished by the substitution of one phoneme, /n/, for another phoneme, /ŋ/. Two words like this that differ in meaning through the contrast of a single phoneme form a minimal pair.
Rhotic consonantIn phonetics, rhotic consonants, or "R-like" sounds, are liquid consonants that are traditionally represented orthographically by symbols derived from the Greek letter rho, including , in the Latin script and , in the Cyrillic script. They are transcribed in the International Phonetic Alphabet by upper- or lower-case variants of Roman , : r, ɾ, ɹ, ɻ, ʀ, ʁ, ɽ, and ɺ. Transcriptions for vocalic or semivocalic realisations of underlying rhotics include the ə and ɐ.
Old FrenchOld French (franceis, françois, romanz; Modern French: ancien français) was the language spoken in most of the northern half of France approximately between the 8th and the 14th century. Rather than a unified language, Old French was a linkage of Romance dialects, mutually intelligible yet diverse. These dialects came to be collectively known as the langue d'oïl, contrasting with the langue d'oc in the south of France. The mid-14th century witnessed the emergence of Middle French, the language of the French Renaissance in the Île de France region; this dialect was a predecessor to Modern French.
Welsh phonologyThe phonology of Welsh is characterised by a number of sounds that do not occur in English and are rare in European languages, such as the voiceless alveolar lateral fricative [ɬ] and several voiceless sonorants (nasals and liquids), some of which result from consonant mutation. Stress usually falls on the penultimate syllable in polysyllabic words, while the word-final unstressed syllable receives a higher pitch than the stressed syllable. Welsh has the following consonant phonemes: Symbols in parentheses are either allophones, or found only in loanwords.
Russian phonologyThis article discusses the phonological system of standard Russian based on the Moscow dialect (unless otherwise noted). For an overview of dialects in the Russian language, see Russian dialects. Most descriptions of Russian describe it as having five vowel phonemes, though there is some dispute over whether a sixth vowel, ɨ, is separate from /i/. Russian has 34 consonants, which can be divided into two types: hard (твёрдый Ru-твёрдый.ogg) or plain soft (мягкий Ru-мягкий.
