Reconstruction

The adjective is *þiudiskaz in Wiktionary and Ringe,[1][2] *þeudiska- in Kroonen and Köbler,[3][4] and *þeuđiskaz in Orel.[5]

Etymology

It is formed from Proto-Germanic *þeudō (“people, nation”) + *-iskaz;[1][5] Feist too derives the adverb from Gothic 𐌸𐌹𐌿𐌳𐌰 (þiuda, “people”) with the suffix *-iska-.[6]

Morphology

An adjective in *-iska-.[2] Ringe says that this suffix formed adjectives of characteristic in Proto-Germanic, as in *manniskaz "human" and *þiudiskaz "tribal"; a suffix *-isko- is widespread in the European branches of Indo-European, but its function is hard to determine.[2]

Evidence

The word is attested in all three branches.[5] Gothic has only the adverb Gothic 𐌸𐌹𐌿𐌳𐌹𐍃𐌺𐍉 (þiudisko, “in the manner of the gentiles”) at Galatians 2:14, translating a Greek adverb.[7] Orel lists Old Norse þýðverskr (“German”), which he finds phonetically irregular and perhaps a loan, Old English þēodisc (“gentile, belonging to a people”), Old Saxon thiudisk and Old High German diutisc.[5] Kroonen notes that the base word was tied to cultural and above all linguistic identity, which gave Old High German diutisk (“the people's language”).[3]

The word is recorded first in Medieval Latin, as Medieval Latin theodiscus: EWA cites an Anglo-Saxon synod of 786, whose decisions were to be read "tam latine quam theodisce", and the judgment against Duke Tassilo of 788, "quod theodisca lingua harisliz dicitur".[8] The native Old High German word appears only in the 10th century, in the Tegernsee glosses to Virgil and then in Notker.[8]

Meanings

  1. of the people, popular, national[1][4]
  2. of the tribe, tribal[1][2]

Gothic used the adverb for "like the heathen",[7] and Old English the adjective for "heathen" and, as a noun, for "language".[6] Medieval Latin theodiscus meant "vernacular, not Latin", while in Notker the Old High German word already means "German".[8]

Reflexes

  • Gothic: 𐌸𐌹𐌿𐌳𐌹𐍃𐌺𐍉 (þiudisko, “in the manner of the gentiles”), an adverb[7]
  • Old Norse: þýðverskr (“German”)[9]
  • Old English: þēodisc (“gentile, belonging to a people”), in Orel's list[5]
  • Old Frisian: thiūdisk (“German, Dutch”)[10]
  • Old Saxon: thiudisk (“of the people, German”)[11]
  • Old High German: diutisc (“German”)[8]
