Apical consonantAn 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.
Yanyuwa languageYanyuwa (jaṉuwa) is the language of the Yanyuwa people of the Sir Edward Pellew Group of Islands in the Gulf of Carpentaria outside Borroloola (Burrulula) in the Northern Territory, Australia. Yanyuwa, like many other Australian Aboriginal languages, is a highly agglutinative language with ergative-absolutive alignment, whose grammar is pervaded by a set of 16 noun classes whose agreements are complicated and numerous. Yanyuwa is a critically endangered language.
Tiwi languageTiwi ˈtiːwi is an Australian Aboriginal language spoken by the Tiwi people on the Tiwi Islands, within sight of the coast of northern Australia. It is one of about 10% of Australian languages still being frequently learned by children. Traditional Tiwi, spoken by people over the age of fifty by 2005, is a polysynthetic language. However, this grammatical complexity has been lost among younger generations. Tiwi has around one hundred nominals that can be incorporated into verbs, most of them quite different from the corresponding free forms.
Morphosyntactic alignmentIn linguistics, morphosyntactic alignment is the grammatical relationship between arguments—specifically, between the two arguments (in English, subject and object) of transitive verbs like the dog chased the cat, and the single argument of intransitive verbs like the cat ran away. English has a subject, which merges the more active argument of transitive verbs with the argument of intransitive verbs, leaving the object distinct; other languages may have different strategies, or, rarely, make no distinction at all.
Tap and flap consonantsIn phonetics, a flap or tap is a type of consonantal sound, which is produced with a single contraction of the muscles so that one articulator (such as the tongue) is thrown against another. The main difference between a tap or flap and a stop is that in a tap/flap there is no buildup of air pressure behind the place of articulation and consequently no release burst. Otherwise a tap/flap is similar to a brief stop. Taps and flaps also contrast with trills, where the airstream causes the articulator to vibrate.
Areal featureIn geolinguistics, areal features are elements shared by languages or dialects in a geographic area, particularly when such features are not descended from a proto-language, or, common ancestor language. That is, an areal feature is contrasted to lingual-genealogically determined similarity within the same language family. Features may diffuse from one dominant language to neighbouring languages (see "sprachbund"). Genetic relationships are represented in the family tree model of language change, and areal relationships are represented in the wave model.
Split ergativityIn linguistic typology, split ergativity is a feature of certain languages where some constructions use ergative syntax and morphology, but other constructions show another pattern, usually nominative–accusative. The conditions in which ergative constructions are used varies among different languages. Ergative–absolutive alignment Nominative–accusative languages (including European languages, with the notable exception of Basque) treat both the actor in a clause with a transitive verb and the experiencer in a clause with an intransitive verb in the same way grammatically.
GlottologGlottolog is a bibliographic database of the world's lesser-known languages, developed and maintained first at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany (between 2015 and 2020 at the Max Planck Institute for the Science of Human History in Jena, Germany). Its main curators include Harald Hammarström and Martin Haspelmath. Sebastian Nordhoff and Harald Hammarström created the Glottolog/Langdoc project in 2011. The creation of Glottolog was partly motivated by the lack of a comprehensive language bibliography, especially in Ethnologue.
Alveolo-palatal consonantIn phonetics, alveolo-palatal (alveolopalatal, alveo-palatal or alveopalatal) consonants, sometimes synonymous with pre-palatal consonants, are intermediate in articulation between the coronal and dorsal consonants, or which have simultaneous alveolar and palatal articulation. In the official IPA chart, alveolo-palatals would appear between the retroflex and palatal consonants but for "lack of space".
Tripartite alignmentIn linguistic typology, tripartite alignment is a type of morphosyntactic alignment in which the main argument ('subject') of an intransitive verb, the agent argument ('subject') of a transitive verb, and the patient argument ('direct object') of a transitive verb are each treated distinctly in the grammatical system of a language. This is in contrast with nominative-accusative and ergative-absolutive alignment languages, in which the argument of an intransitive verb patterns with either the agent argument of the transitive (in accusative languages) or with the patient argument of the transitive (in ergative languages).
