Gothic languageGothic is an extinct East Germanic language that was spoken by the Goths. It is known primarily from the Codex Argenteus, a 6th-century copy of a 4th-century Bible translation, and is the only East Germanic language with a sizeable text corpus. All others, including Burgundian and Vandalic, are known, if at all, only from proper names that survived in historical accounts, and from loanwords in other languages such as Portuguese, Spanish, Catalan, Occitan and French. As a Germanic language, Gothic is a part of the Indo-European language family.
Proto-Indo-European languageProto-Indo-European (PIE) is the reconstructed common ancestor of the Indo-European language family. No direct record of Proto-Indo-European exists; its proposed features have been derived by linguistic reconstruction from documented Indo-European languages. Far more work has gone into reconstructing PIE than any other proto-language, and it is the best understood of all proto-languages of its age.
GaulishGaulish is an extinct Celtic language spoken in parts of Continental Europe before and during the period of the Roman Empire. In the narrow sense, Gaulish was the language of the Celts of Gaul (now France, Luxembourg, Belgium, most of Switzerland, Northern Italy, as well as the parts of the Netherlands and Germany on the west bank of the Rhine). In a wider sense, it also comprises varieties of Celtic that were spoken across much of central Europe ("Noric"), parts of the Balkans, and Anatolia ("Galatian"), which are thought to have been closely related.
DialectDialect (from Latin dialectus, dialectos, from the Ancient Greek word διάλεκτος, 'discourse', from διά, 'through' and λέγω, 'I speak') can refer to two distinctly different types of linguistic phenomena. One usage refers to a variety of a language that is a characteristic of a particular group of the language's speakers. Under this definition, the dialects or varieties of a particular language are closely related and, despite their differences, are most often largely mutually intelligible, especially if geographically close to one another in a dialect continuum.
West Germanic languagesThe West Germanic languages constitute the largest of the three branches of the Germanic family of languages (the others being the North Germanic and the extinct East Germanic languages). The West Germanic branch is classically subdivided into three branches: Ingvaeonic, which includes English and Frisian, Istvaeonic, which encompasses Dutch and its close relatives, and Irminonic, which includes German and its close relatives and variants. English is by far the most-spoken West Germanic language, with more than 1 billion speakers worldwide.
Genetic relationship (linguistics)Two languages have a genetic relationship, and belong to the same language family, if both are descended from a common ancestor through the process of language change, or one is descended from the other. The term and the process of language evolution are independent of, and not reliant on, the terminology, understanding, and theories related to genetics in the biological sense, so, to avoid confusion, some linguists prefer the term genealogical relationship.
