Forms

tveir (feminine tvær, neuter tvau)[1]

Etymology

It is inherited from Proto-Germanic *twai (“two”),[1][2][3] the numeral also in Gothic 𐍄𐍅𐌰𐌹 (twai), Old English twēgen, Old Saxon twēne and Old High German zwēne.[2][4] Kroonen reconstructs the Proto-Germanic forms as masculine *twai, accusative *twans, feminine *twōz, genitive *twajjan and dative *twaimiz, which give Old Norse “tvá”, “tvær”, “tveggja” and “tveim(r)”.[2] De Vries takes “tveir” as a new formation on Proto-Norse *twai, and Ásgeir Blöndal Magnússon explains it as “*twai” with the plural ending “-ʀ”.[5][6]

The numeral continues Proto-Indo-European *dwóh₁ (“two”),[1] the source also of Latin duo, Ancient Greek δύο (dúo) and Proto-Slavic *dъva.[4][6]

Earliest recorded meaning

The earliest dated record is the Swedish Rök stone (Ög 136), which Rundata dates to the ninth century; its text has the feminine tuaR “two” and the masculine kunukaR tuaiR “two kings”.[7] In Norwegian manuscripts it is first dated in the fragment NRA norr fragm 81 A of 1150–1250, with tvær.[8]

Semantic evolution

Beside the plain numeral, tveir gives set phrases: báðir tveir “both”, tveim hǫndum “with both hands”, í tvau “in two, asunder”, and the proverb tveimr er tveggja hugr “two men, two minds”.[9][10] In verse tvær can stand for “both”, as in rjóða tvær eggjar “to redden both edges”.[11]

Icelandic tveir and Faroese tveir keep the nominative, while Swedish två and Danish to continue the masculine accusative tvá.[6][12]
