Reconstruction

De Vaan sets up West Germanic *þus "thus" as the source of the Dutch adverb and its Old Saxon, Old Frisian and Old English cognates,[1] and Wiktionary has the same form, naming no Proto-Germanic ancestor.[2]

Etymology

It is inherited from Proto-Germanic *þus (“so”) in Köbler's reconstruction, an adverb of unknown etymology,[3] and Boutkan and Siebinga trace the word to a Proto-Germanic element *þu-.[4]

Morphology

An adverb.[5][6] Old High German, Old Saxon, Middle Low German and Middle Dutch also have a variant with initial s-, Old High German sus (“so”) in the Hildebrandslied.[6]

Evidence

The adverb is attested in Old English þus, Old Frisian thus and Old Saxon thus,[1] and Old Dutch has thus in Williram's commentary of about 1100.[7] Old High German dus occurs only once, in the De Heinrico of the 11th century, a text in a Franconian dialect of central Germany, and the derived adjective once in a Middle Franconian gloss of the 9th century.[6] Boutkan and Siebinga count the formation among those found only in part of West Germanic, while reporting Schmidt's view that the blend sus shows it for Old High German too.[4]

Competing analyses

Sievers held *þus to be the older form and traced it to the demonstrative stem *to-, and Lerchner agreed.[6] Berr likewise connects it with the demonstrative.[8] According to Schmidt, *þu- either matches a Sanskrit particle meaning "but, rather", or was formed after the Proto-Germanic word for "how", with an *-s from a weak by-form of the word for "so".[6] EWA notes that a preform *þu-se with final -s would have to have been stressed at the time of Verner's law and weakly stressed later, since it shows no a-umlaut; it also discusses the alternative that sus is the original form, from *swe-se.[6] Boutkan and Siebinga find *þu-sa, with a by-form of *swa "thus" without w, problematic because of the missing a-umlaut, prefer an element *-se as in Latin sed (“but”), and call a connection with the s of the word for "this" speculative; for *þu- they consider a Proto-Indo-European particle *tu, for which only a Sanskrit word meaning "now, but" is evidence.[4]

Meanings

  1. thus, in this way[1][2]

Derivatives

  • EWA traces Old High German duslīh (“such”), Old English þyslic and Old Frisian thusk to a preform *þus-līka-, with the adverb as its first element.[6]
