The adjective is derived from Early Middle English thwert, thwerte, thuart, thurt, thurte, thwart, thwarte, twart, twarte, twhart, twhert, twort, þuert, þwerrt, þwert, þwerte, ðwert (“crosswise, transverse; counter, opposing; contrary, obstinate”),^[1] borrowed from Old Norse þvert (“across, athwart”), originally the neuter form of þverr (“across, transverse”),^[2] from Proto-Germanic *þwerhaz (“cross; adverse”) (altered or influenced by Proto-Germanic *þweraną (“to stir; to swirl; to turn”)), from Proto-Germanic *þerh-, probably from Proto-Indo-European *terkʷ- (“to spin; to turn”).

The English adjective is cognate with Danish tvær (“sullen, sulky”), Gothic 𐌸𐍅𐌰𐌹𐍂𐍃 (þwairs, “angry”), Middle Dutch dwers, dwars (modern Dutch dwars (“crosswise, transverse; slantwise, askew; stubbornly disobedient”)), Norwegian tvert, tvært, Old Frisian þweres, dwers (Saterland Frisian twars, West Frisian dwers, dwerz (“across, to the other side of; beyond”)), Middle Low German dwers, dwars (Low German dwars (“contrary; cross-grained”)), Old English þweorh (“transverse; perverse; angry, cross”), Old High German twer (Middle High German twer, quer, modern German quer (“crosswise; cross”)), Swedish tvär (“across, transverse; of a curve: sharp; immediate, sudden; grumpy, stubborn”).^[2] It is related to queer; also Proto-West Germanic *þwerh,

The adverb is derived from Middle English thwert, ywerte (“crosswise; across the grain”); the Middle English Dictionary suggests the adverb was derived from the adjective,^[3] while the Oxford English Dictionary notes that the adverb is attested earlier than the adjective.^[2]

The verb is derived from Middle English thwerten, thwert, thwarten, þwerten (“to lie across; to oppose, to thwart”),^[4] and further from the adverb^[5] and perhaps also the adjective.^[4]

Noun sense 1 (“a seat across a boat on which a rower may sit”) may be derived from the adverb or adjective, from the position of the seat across the length of the boat,^[6] while noun sense 3 (“(rare) an act of thwarting”) is derived from the verb.^[7] Compare Middle English thwert (“in in thwert: crosswise”), from the adjective.^[8]
