Language is a structured system of communication that consists of grammar and vocabulary. It is the primary means by which humans convey meaning, both in spoken and written forms, and may also be conveyed through sign languages. Human language is characterized by its cultural and historical diversity, with significant variations observed between cultures and across time. Human languages possess the properties of productivity and displacement, which enable the creation of an infinite number of sentences, and the ability to refer to objects, events, and ideas that are not immediately present in the discourse. The use of human language relies on social convention and is acquired through learning.
In linguistics, morphology is the study of words, including the principles by which they are formed, and how they relate to one another within a language. Most approaches to morphology investigate the structure of words in terms of morphemes, which are the smallest units in a language with some independent meaning. Morphemes include roots that can exist as words by themselves, but also categories such as affixes that can only appear as part of a larger word. For example, in English the root catch and the suffix -ing are both morphemes; catch may appear as its own word, or it may be combined with -ing to form the new word catching. Morphology also analyzes how words behave as parts of speech, and how they may be inflected to express grammatical categories including number, tense, and aspect. Concepts such as productivity are concerned with how speakers create words in specific contexts, which evolves over the history of a language.
In linguistics, grammatical number is a feature of nouns, pronouns, adjectives and verb agreement that expresses count distinctions. English and other languages present number categories of singular or plural, both of which are cited by using the hash sign (#) or by the numero signs "No." and "Nos." respectively. Some languages also have a dual, trial and paucal number or other arrangements.
A word is a basic element of language that carries meaning, can be used on its own, and is uninterruptible. Despite the fact that language speakers often have an intuitive grasp of what a word is, there is no consensus among linguists on its definition and numerous attempts to find specific criteria of the concept remain controversial. Different standards have been proposed, depending on the theoretical background and descriptive context; these do not converge on a single definition. Some specific definitions of the term "word" are employed to convey its different meanings at different levels of description, for example based on phonological, grammatical or orthographic basis. Others suggest that the concept is simply a convention used in everyday situations.
Babine–Witsuwitʼen or Nadotʼen-Wetʼsuwetʼen is an Athabaskan language spoken in the Central Interior of British Columbia. Its closest relative is Carrier. Because of this linguistic relationship together with political and cultural ties, Babine–Witsuwitʼen is often referred to as Northern Carrier or Western Carrier. Specialist opinion is, however, that it should be considered a separate, though related, language.
Macro-Pama-Nyungan is an umbrella term used to refer to a proposed Indigenous Australian language family. It was coined by the Australian linguist Nicholas Evans in his 1996 book Archaeology and linguistics: Aboriginal Australia in global perspective, co-authored by Patrick McConvell. The term arose from Evans' theory suggesting that two of the largest Indigenous Australian language families share a common origin, and should therefore be classified as a singular language family under "Macro-Pama-Nyungan".
Murrinh-patha, called Garama by the Jaminjung, is an Australian Aboriginal language spoken by over 2,000 people, most of whom live in Wadeye in the Northern Territory, where it is the dominant language of the community. It is spoken by the Murrinh-Patha people, as well as several other peoples whose languages are extinct or nearly so, including the Mati Ke and Marri-Djabin. It is believed to be the most widely spoken Australian Aboriginal language not belonging to the Pama-Nyungan language family.
Huave is a language isolate spoken by the indigenous Huave people on the Pacific coast of the Mexican state of Oaxaca. The language is spoken in four villages on the Isthmus of Tehuantepec, in the southeast of the state, by around 20,000 people.
English is a West Germanic language in the Indo-European language family, whose speakers, called Anglophones, originated in early medieval England. The namesake of the language is the Angles, one of the ancient Germanic peoples that migrated to the island of Great Britain.
Havasupai–Hualapai (Havasupai–Walapai) is the Native American language spoken by the Hualapai and Havasupai peoples of northwestern Arizona. Havasupai–Hualapai belongs to the Pai branch of the Yuman–Cochimí language family, together with its close relative Yavapai and with Paipai, a language spoken in northern Baja California. There are two main dialects of this language: the Havasupai dialect is spoken in the bottom of the Grand Canyon, while the Hualapai dialect is spoken along the southern rim. As of 2010, there were approximately 1500 speakers of Havasupai-Hualapai. UNESCO classifies the Havasupai dialect as endangered and the Hualapai dialect as vulnerable. There are efforts at preserving both dialects through bilingual education programs.
Kachari is a Sino-Tibetan language of the Boro-Garo branch that is spoken in Assam, India. With fewer than 60,000 speakers recorded in 1997, and the Asam 2001 Census reporting a literacy rate of 81% the Kachari language is currently ranked as threatened. Kachari is closely related to surrounding languages, including Tiwa, Rābhā, Hajong, Kochi and Mechi.
Lardil, also spelled Leerdil or Leertil, is a moribund language spoken by the Lardil people on Mornington Island (Kunhanha), in the Wellesley Islands of Queensland in northern Australia. Lardil is unusual among Aboriginal Australian languages in that it features a ceremonial register, called Damin. Damin is regarded by Lardil-speakers as a separate language and has the only phonological system outside Africa to use click consonants.
Dalabon is a Gunwinyguan language of Arnhem Land, Australia. It is a severely endangered language, with perhaps as few as three fluent speakers remaining as of 2018. Dalabon is also known as Dangbon, Ngalkbun, and Buwan.
Moloko (Məlokwo) is an Afro-Asiatic language spoken in northern Cameroon.
In linguistic morphology, inflection is a process of word formation in which a word is modified to express different grammatical categories such as tense, case, voice, aspect, person, number, gender, mood, animacy, and definiteness. The inflection of verbs is called conjugation, and one can refer to the inflection of nouns, adjectives, adverbs, pronouns, determiners, participles, prepositions and postpositions, numerals, articles, etc., as declension.
Mehek is a Tama language spoken by about 6300 people in a somewhat mountainous area along the southern base of the Torricelli Mountains in northwestern Papua New Guinea. Mehek is spoken in six villages of Sandaun Province: Nuku, Yiminum, Mansuku, Yifkindu, Wilwil, and Kafle. Mehek is most closely related to Pahi, with 51% lexical similarity, and spoken approximately 20 kilometers to the southwest. Mehek is a fairly typical Papuan language, being verb-final, having a relatively simple phonology, and agglutinative morphology. There is very little published information about Mehek. The literacy rate in Tok Pisin, spoken by nearly everyone, is 50-75%. Mehek is not written, so there is no literacy in Mehek. Tok Pisin is primarily used in the schools, with 50% children attending. There is also a sign language used by the large number of deaf people in the Mehek community.
The Yukulta language, also spelt Yugulda, Yokula, Yukala, Jugula, and Jakula, and also known as Ganggalidda, is an extinct Tangkic language spoken in Queensland and Northern Territory, Australia.
