Proto-Slavic in the context of "Grad (toponymy)"

The early Slavs were an Indo-European peoples and speakers of the Indo-European dialectswho lived during the Migration Period and the Early Middle Ages (approximately from the 5th to the 10th centuries AD) in Central, Eastern and Southeast Europe and established the foundations for the Slavic nations through the Slavic states of the Early and High Middle Ages. The Slavs' original homeland is still a matter of debate due to a lack of historical records; however, scholars generally place it in Eastern Europe, with Polesia being the most commonly accepted location.

It is generally agreed that ancient Roman writers referred to the ancestors of Slavs as Venedi. The proto-Slavic term Slav shares roots with Slavic terms for speech, word, and perhaps was used by early Slavic people themselves to denote other people, who spoke languages similar to theirs. The first written use of the name "Slavs" dates to the 6th century, when the Slavic tribes inhabited a large portion of Central and Eastern Europe. By then, the nomadic Iranian-speaking peoples living in the European Pontic Steppe (the Scythians, Sarmatians, Alans, etc.) had been absorbed by the region's Slavic-speaking population. Over the next two centuries, the Slavs expanded westwards (to the Elbe river and in the Alps), and southwards (into the Balkans, absorbing Illyrian and Thracian peoples in the process), and also moved eastwards (in the direction of the Volga River). Between the sixth and seventh centuries, large parts of Europe came to be controlled or occupied by Slavs, a process less understood and documented than that of the Germanic ethnogenesis in the west. Yet the effects of Slavicization were far more profound.

There are many widely varying names of Germany in different languages, more so than for any other European nation. For example:

• the German language endonym is Deutschland, from the Old High German diutisc, meaning "of the people";
• the French exonym is Allemagne, from the name of the Alamanni tribe;
• in Italian it is Germania, from the Latin Germania, although the German people are called tedeschi, which is cognate with German Deutsch;
• in Polish it is Niemcy, from the Proto-Slavic *němьcь, meaning speechless, since German is not mutually intelligible with Slavic languages;
• in Finnish it is Saksa, from the name of the Saxon tribe;
• in Lithuanian it is Vokietija, of unclear origin, but possibly from Proto-Balto-Slavic *vākyā-, meaning “those who speak loud, shout (unintelligibly)”.

Often language lags behind the changing society and names tend to retain references to first encounters: the Finnish first and foremost met the Saxons while the French faced the Alamanni. Comparable tendencies appear elsewhere, e.g. in names for Russia.

Shtokavian or Štokavian (/ʃtɒˈkɑːviən, -ˈkæv-/; Serbo-Croatian Latin: štokavski / Serbo-Croatian Cyrillic: штокавски, pronounced [ʃtǒːkaʋskiː]) is the prestige supradialect of the pluricentric Serbo-Croatian language and the basis of its Bosnian, Croatian, Montenegrin and Serbian standards. It is a part of the South Slavic dialect continuum. Its name comes from the form for the interrogative pronoun for "what": što. This is in contrast to dialects that are exclusive to Croatian language: Kajkavian and Chakavian (kaj and ča also meaning "what").

Shtokavian is spoken in Bosnia and Herzegovina, the southern part of Austria's Burgenland, much of Croatia, Montenegro, Bosnia and Herzegovina and Serbia. The primary subdivisions of Shtokavian are based on three principles: one is different accents (whether the subdialect is Old-Shtokavian or Neo-Shtokavian), second is the way the old Slavic phoneme yat has changed (Ikavian, Ijekavian or Ekavian), and third is the presence of the Young Proto-Slavic isogloss (Schakavian or Shtakavian). Modern dialectology generally recognises seven Shtokavian subdialects.

The Polish language is a West Slavic language, and thus descends from Proto-Slavic, and more distantly from Proto-Indo-European; more specifically, it is a member of the Lechitic branch of the West Slavic languages, along with other languages spoken in areas within or close to the area of modern Poland: including Kashubian, Silesian, and the extinct Slovincian and Polabian.

The separation of Polish as a language is conventionally dated at the second half of the 10th century, linked with the establishment of Polish statehood and the Christianization of Poland. The history of the language can then be divided into the following periods periods of development: Old Polish (staropolski) with a pre-literate, pre-Polish era up to 1136, the literate era from 1136 with the Bull of Gniezno up to the start of the 16th century; Middle Polish (średniopolski) from the 16th century until the end of the 18th century (1772) with the first parition of the Polish–Lithuanian Commonwealth; New Polish (nowopolski) from 1772-1939; and Modern Polish, since World War II.

A vozhd (romanised from Belarusian, Russian and Ukrainian: вождь, also Bulgarian, Macedonian and Serbo-Croatian: вожд, romanized: vožd, Czech: vůdce, Polish: wódz, Slovak: vodca, or Slovene: vodja), literally meaning "the guidesperson" or "the leader", is a historical title with etymology deriving from the Proto-Slavic *voďь and thus common across Slavic languages. It denoted a chieftain of a tribe.

A pan-Slavic language is a zonal auxiliary language for communication among the Slavic peoples.

There are approximately 400 million speakers of the Slavic languages. In order to communicate with each other, speakers of different Slavic languages often resort to international lingua francas, primarily English or Russian. But since Slavic languages are closely related lexically and grammatically and are comparatively easier to learn when another Slavic language is already known, there have been numerous attempts to construct a more neutral auxiliary language that could act as a common language for slavophones. The earliest pan-Slavic linguistic efforts preceded academic knowledge and reconstruction of Proto-Slavic, which was likely spoken between 2nd century BCE and 6th century CE, from which all Slavic languages developed in following centuries.
