Lombardic or Langobardic is an extinct West Germanic language that was spoken by the Lombards (Langobardi), the Germanic people who settled in Italy in the sixth century. It was already declining by the seventh century because the invaders quickly adopted the Latin vernacular spoken by the local population. Lombardic may have been in use in scattered areas until as late as 1000 AD. Many toponyms in modern Lombardy and Greater Lombardy (Northern Italy) and items of Lombard and broader Gallo-Italic vocabulary derive from Lombardic. Lombardic is a Trümmersprache (literally, 'rubble-language'), that is, a language preserved only in fragmentary form: there are no texts in Lombardic, only individual words and personal names cited in Latin law codes, histories and charters. As a result, there are many aspects of the language about which nothing is known. Lombardic is classified as part of the Elbe Germanic (Upper German) group of West Germanic languages, most closely related to its geographical neighbours Alemannic and Bavarian. This is consistent with the accounts of classical historians, and indeed with the archaeological evidence of Langobardic settlement along the river Elbe. In view of the lack of Lombardic texts and the narrow scope of the attested Lombardic vocabulary — almost entirely nouns in the nominative case and proper names — the classification rests entirely on phonology. Here the clear evidence of the Second Sound Shift shows that the language must be High German, rather than North Sea Germanic or East Germanic, as some earlier scholars proposed. The main evidence for Lombardic comes from contemporary documents written in Latin, where (a) individual Lombardic terms are cited and (b) people with Lombardic names are mentioned. There are also a small number of inscriptions, a handful of which use the Runic alphabet. Additional information about the vocabulary of Lombardic comes from later-attested loan words into Italian and its dialects, as well as a large number of Italian place names of Lombardic origin (see below).
