Proto-Pama–Nyungan Language
Proto-Pama–Nyungan is the hypothetical common ancestor of the Pama–Nyungan languages. It may have been spoken as recently as about 5,000 years ago, much more recently than the 40,000 to 60,000 years indigenous Australians are believed to have been inhabiting Australia. Evolution How the Pama–Nyungan languages spread over most of the continent and displaced any pre-Pama–Nyungan languages is uncertain; one possibility is that language could have been transferred from one group to another alongside culture and ritual. Given the relationship of cognates between groups, it seems that Pama-Nyungan has many of the characteristics of a sprachbund, indicating the antiquity of multiple waves of culture contact between groups. Dixon in particular has argued that the genealogical trees found with many language families do not fit in the Pama-Nyungan family. Using computational phylogenetics, Bouckaert, et al.

Low Vowel
An open vowel is a vowel sound in which the tongue is positioned as far as possible from the roof of the mouth. Open vowels are sometimes also called low vowels (in U.S. terminology ) in reference to the low position of the tongue. In the context of the phonology of any particular language, a ''low vowel'' can be any vowel that is more open than a mid vowel. That is, open-mid vowels, near-open vowels, and open vowels can all be considered low vowels. Partial list The open vowels with dedicated symbols in the International Phonetic Alphabet are: * open front unrounded vowel * open front rounded vowel This vowel is not known to occur as a phoneme distinct from in any language. * open back unrounded vowel * open back rounded vowel There also are central vowels that do not have dedicated symbols in the IPA: * open central unrounded vowel or (commonly written as if it were front) * open central rounded vowel There is no unambiguous way of transcribing the open central ...

Rhotic Consonant
In phonetics, rhotic consonants, or "R-like" sounds, are liquid consonants that are traditionally represented orthography, orthographically by symbols derived from the Greek alphabet, Greek letter Rho (letter), rho, including R, , in the Latin script and Er (Cyrillic), , in the Cyrillic script. They are transcribed in the International Phonetic Alphabet by upper- or lower-case variants of Roman , : , , , , , , , and as well as by the lower-case turned Roman (the symbol for the near-open central vowel) combined with the "non-syllabic" diacritic, that is . This class of sounds is difficult to characterise phonetically; from a phonetic standpoint, there is no single articulatory correlate (manner of articulation, manner or place of articulation, place) common to rhotic consonants. Rhotics have instead been found to carry out similar phonological functions or to have certain similar phonological features across different languages. Being "R-like" is an elusive and ambiguous con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lateral Consonant
A 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. The most common laterals are approximant Approximants 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 ...s and belong to the class of liquid consonant, liquids, but lateral fricative consonant, fricatives and affricate co ...

Nasal Stop
In phonetics, a nasal, also called a nasal occlusive or nasal stop in contrast with an oral stop or nasalized consonant, is an occlusive consonant produced with a lowered velum, allowing air to escape freely through the nose. The vast majority of consonants are oral consonants. Examples of nasals in English are , and , in words such as ''nose'', ''bring'' and ''mouth''. Nasal occlusives are nearly universal in human languages. There are also other kinds of nasal consonants in some languages. Definition Nearly all nasal consonants are nasal occlusives, in which air escapes through the nose but not through the mouth, as it is blocked (occluded) by the lips or tongue. The oral cavity still acts as a resonance chamber for the sound. Rarely, non-occlusive consonants may be nasalized. Most nasals are voiced, and in fact, the nasal sounds and are among the most common sounds cross-linguistically. Voiceless nasals occur in a few languages such as Burmese, Welsh, Icelandic and ...

Plosive Consonant
In phonetics, a plosive, also known as an occlusive or simply a stop, is a pulmonic consonant in which the vocal tract is blocked so that all airflow ceases. The occlusion may be made with the tongue tip or blade (, ), tongue body (, ), lips (, ), or glottis (). Plosives contrast with nasals, where the vocal tract is blocked but airflow continues through the nose, as in and , and with fricatives, where partial occlusion impedes but does not block airflow in the vocal tract. Terminology The terms ''stop, occlusive,'' and ''plosive'' are often used interchangeably. Linguists who distinguish them may not agree on the distinction being made. The terms refer to different features of the consonant. "Stop" refers to the airflow that is stopped. "Occlusive" refers to the articulation, which occludes (blocks) the vocal tract. "Plosive" refers to the release burst (plosion) of the consonant. Some object to the use of "plosive" for inaudibly released stops, which may then instead be ca ...

Retroflex Consonant
A retroflex ( /ˈɹɛtʃɹoːflɛks/), apico-domal ( /əpɪkoːˈdɔmɪnəl/), or cacuminal () consonant is a coronal consonant where the tongue has a flat, concave, or even curled shape, and is articulated between the alveolar ridge and the hard palate. They are sometimes referred to as cerebral consonants—especially in Indology. The Latin-derived word ''retroflex'' means "bent back"; some retroflex consonants are pronounced with the tongue fully curled back so that articulation involves the underside of the tongue tip ( subapical). These sounds are sometimes described as "true" retroflex consonants. However, retroflexes are commonly taken to include other consonants having a similar place of articulation without such extreme curling of the tongue; these may be articulated with the tongue tip (apical) or the tongue blade (laminal). Types Retroflex consonants, like other coronal consonants, come in several varieties, depending on the shape of the tongue. The tongue may be eith ...

Alveolar Consonant
Alveolar (; UK also ) consonants are articulated with the tongue against or close to the superior alveolar ridge, which is called that because it contains the alveoli (the sockets) of the upper teeth. Alveolar consonants may be articulated with the tip of the tongue (the apical consonants), as in English, or with the flat of the tongue just above the tip (the "blade" of the tongue; called laminal consonants), as in French and Spanish. The International Phonetic Alphabet (IPA) does not have separate symbols for the alveolar consonants. Rather, the same symbol is used for all coronal places of articulation that are not palatalized like English palato-alveolar ''sh'', or retroflex. To disambiguate, the ''bridge'' (, ''etc.'') may be used for a dental consonant, or the under-bar (, ''etc.'') may be used for the postalveolars. differs from dental in that the former is a sibilant and the latter is not. differs from postalveolar in being unpalatalized.

Postalveolar Consonant
Postalveolar or post-alveolar consonants are consonants articulated with the tongue near or touching the ''back'' of the alveolar ridge. Articulation is farther back in the mouth than the alveolar consonants, which are at the ridge itself, but not as far back as the hard palate, the place of articulation for palatal consonants. Examples of postalveolar consonants are the English palato-alveolar consonants , as in the words "ship", "'chill", "vision", and "jump", respectively. There are many types of postalveolar sounds—especially among the sibilants. The three primary types are '' palato-alveolar'' (such as , weakly palatalized), ''alveolo-palatal'' (such as , strongly palatalized), and ''retroflex'' (such as , unpalatalized). The palato-alveolar and alveolo-palatal subtypes are commonly counted as "palatals" in phonology since they rarely contrast with true palatal consonants. Postalveolar sibilants For most sounds involving the tongue, the place of articulation can be suffi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Velar Consonant
Velars are consonants articulated with the back part of the tongue (the dorsum) against the soft palate, the back part of the roof of the mouth (known also as the velum). Since the velar region of the roof of the mouth is relatively extensive and the movements of the dorsum are not very precise, velars easily undergo assimilation, shifting their articulation back or to the front depending on the quality of adjacent vowels. They often become automatically ''fronted'', that is partly or completely palatal before a following front vowel, and ''retracted'', that is partly or completely uvular before back vowels. Palatalised velars (like English in ''keen'' or ''cube'') are sometimes referred to as palatovelars. Many languages also have labialized velars, such as , in which the articulation is accompanied by rounding of the lips. There are also labial–velar consonants, which are doubly articulated at the velum and at the lips, such as . This distinction disappears with the approx ...

Bilabial Consonant
In phonetics, a bilabial consonant is a labial consonant articulated with both lips. Frequency Bilabial consonants are very common across languages. Only around 0.7% of the world's languages lack bilabial consonants altogether, including Tlingit, Chipewyan, Oneida, and Wichita. Varieties The bilabial consonants identified by the International Phonetic Alphabet (IPA) are: Owere Igbo has a six-way contrast among bilabial stops: . Other varieties The extensions to the IPA also define a () for smacking the lips together. A lip-smack in the non-percussive sense of the lips noisily parting would be .Heselwood (2013: 121) The IPA chart shades out ''bilabial lateral consonants'', which is sometimes read as indicating that such sounds are not possible. The fricatives and are often lateral, but since no language makes a distinction for centrality, the allophony is not noticeable.

Apical Consonant
An apical consonant is a phone (speech sound) produced by obstructing the air passage with the tip of the tongue (apex) in conjunction with upper articulators from lips to postalveolar, and possibly prepalatal. It contrasts with laminal consonants, which are produced by creating an obstruction with the blade of the tongue, just behind the tip. Sometimes ''apical'' is used exclusively for an articulation that involves only the tip of the tongue and ''apicolaminal'' for an articulation that involves both the tip and the blade of the tongue. However, the distinction is not always made and the latter one may be called simply ''apical'', especially when describing an apical dental articulation. As there is some laminal contact in the alveolar region, the apicolaminal dental consonants are also labelled as ''denti-alveolar''. It is not a very common distinction and is typically applied only to fricatives and affricates. Thus, many varieties of English have either apical or laminal ...
