Bulgarian is an Eastern South Slavic language spoken in Southeast Europe, primarily in Bulgaria. It is the language of the Bulgarians.
Czech, historically also Bohemian, is a West Slavic language of the Czech–Slovak group, written in Latin script. Spoken by over 10 million people, it serves as the official language of the Czech Republic. Czech is closely related to Slovak, to the point of high mutual intelligibility, as well as to Polish to a lesser degree. Czech is a fusional language with a rich system of morphology and relatively flexible word order. Its vocabulary has been extensively influenced by Latin and German.
Polish is a West Slavic language of the Lechitic group written in the Latin script. It is spoken primarily in Poland and serves as the native language of the Poles. In addition to being the official language of Poland, it is also used by the Polish diaspora. There are over 50 million Polish speakers around the world. It ranks as the sixth most-spoken among languages of the European Union. Polish is subdivided into regional dialects and maintains strict T–V distinction pronouns, honorifics, and various forms of formalities when addressing individuals.
In grammar, the vocative case is a grammatical case which is used for a noun that identifies a person being addressed, or occasionally for the noun modifiers of that noun. A vocative expression is an expression of direct address by which the identity of the party spoken to is set forth expressly within a sentence. For example, in the sentence "I don't know, John," John is a vocative expression that indicates the party being addressed, as opposed to the sentence "I don't know John" in which "John" is the direct object of the verb "know".
In grammar, the locative case is a grammatical case which indicates a location. It corresponds vaguely to the English prepositions "in", "on", "at", and "by". The locative case belongs to the general local cases, together with the lative and separative case.
Romani is an Indo-Aryan macrolanguage of the Romani communities. According to Ethnologue, seven varieties of Romani are divergent enough to be considered languages of their own. The largest of these are Vlax Romani, Balkan Romani (600,000), and Sinte Romani (300,000). Some Romani communities speak mixed languages based on the surrounding language with retained Romani-derived vocabulary – these are known by linguists as Para-Romani varieties, rather than dialects of the Romani language itself.
Dual is a grammatical number that some languages use in addition to singular and plural. When a noun or pronoun appears in dual form, it is interpreted as referring to precisely two of the entities identified by the noun or pronoun acting as a single unit or in unison. Verbs can also have dual agreement forms in these languages.
Venedic is a naturalistic constructed language, created by the Dutch translator Jan van Steenbergen. It is used in the fictional Republic of the Two Crowns, based on the Polish–Lithuanian Commonwealth, in the alternate timeline of Ill Bethisad. Officially, Venedic is a descendant of Vulgar Latin with a strong Slavic admixture, based on the premise that the Roman Empire incorporated the ancestors of the Poles in their territory. Less officially, it tries to show what Polish would have looked like if it had been a Romance instead of a Slavic language. On the Internet, it is well-recognized as an example of the altlang genre, much like Brithenig and Breathanach.
The Slovak language is a West Slavic language. Historically, it forms a dialect continuum with Czech. The written standard is based on the work of Ľudovít Štúr, published in the 1840s and codified in July 1843 in Hlboké.
The South Slavic languages are one of three branches of the Slavic languages. There are approximately 30 million speakers, mainly in the Balkans. These are separated geographically from speakers of the other two Slavic branches by a belt of German, Hungarian and Romanian speakers.
Czech declension is a complex system of grammatically determined modifications of nouns, adjectives, pronouns and numerals in Czech, one of the Slavic languages. Czech has seven cases: nominative, genitive, dative, accusative, vocative, locative and instrumental, partly inherited from Proto-Indo-European and Proto-Slavic. Some forms of words match in more than one place in each paradigm.
The Czech–Slovak languages are a subgroup within the West Slavic languages comprising the Czech and Slovak languages.
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.
Sukuma is a Bantu language of Tanzania, spoken in an area southeast of Lake Victoria between Mwanza, Shinyanga, and Lake Eyasi.
Serbo-Croatian is a South Slavic language that, like most other Slavic languages, has an extensive system of inflection. This article describes exclusively the grammar of the Shtokavian dialect, which is a part of the South Slavic dialect continuum and the basis for the Bosnian, Croatian, Montenegrin, and Serbian standard variants of Serbo-Croatian. "An examination of all the major 'levels' of language shows that BCS is clearly a single language with a single grammatical system."
Kanashi is a Sino-Tibetan language spoken in the isolated Malana (Malani) village area in Kullu District, Himachal Pradesh, India. It is, to some extent mutually intelligible with other Sino-Tibetan language like kinnauri.
Mortlockese, also known as Mortlock or Nomoi, is a language that belongs to the Chuukic group of Micronesian languages in the Federated States of Micronesia spoken primarily in the Mortlock Islands. It is nearly intelligible with Satawalese, with an 18 percent intelligibility and an 82 percent lexical similarity, and Puluwatese, with a 75 percent intelligibility and an 83 percent lexical similarity. The language today has become mutually intelligible with Chuukese, though marked with a distinct Mortlockese accent. Linguistic patterns show that Mortlockese is converging with Chuukese since Mortlockese now has an 80 to 85 percent lexical similarity.
Eastern Slovak dialects, are dialects of the Slovak language spoken natively in the historical regions of Spiš, Šariš, Zemplín and Abov, in the east of Slovakia. In contrast to other dialects of Slovak, Eastern dialects are less intelligible with Czech and more with Polish and Rusyn.
Proto-Slavic is the unattested, reconstructed proto-language of all Slavic languages. It represents Slavic speech approximately from the 2nd millennium BC through the 6th century AD. As with most other proto-languages, no attested writings have been found; scholars have reconstructed the language by applying the comparative method to all the attested Slavic languages and by taking into account other Indo-European languages.
Interslavic is a pan-Slavic auxiliary language. Its purpose is to facilitate communication between speakers of various Slavic languages, as well as to allow people who do not speak a Slavic language to communicate with Slavic speakers by being mutually intelligible with most, if not all, Slavic languages. For Slavs and non-Slavs, it can fulfill an educational role as well.
