thwart

Etymology and origin of the English word thwart

Pronunciation

  • IPA: /θwɔːt/ (UK); /θwɔɹt/ (US)[1]

Etymology

It is inherited from Middle English thwerten, from thwert “across”,[2][3][4][5][6] from Old Norse þvert (“across”), the neuter of þverr “transverse”.[2][3][4][5][6] It is related to Old English þweorh “crooked, perverse” and Gothic þwairhs “angry”.[3][4][6] The noun “rower's seat” is an alteration of obsolete thoft, from Old English thofte.[5]

Earliest recorded meaning

As a verb, to oppose or hinder (about 1250).[3][4][5][7]

Semantic evolution

The adverb meant “across, crosswise”,[7][4][3] and the verb had physical senses such as to lie across or to cross (1413).[7][4] The verb's sense of opposing or hindering is the oldest,[3][4][7] and it now usually means to prevent someone from accomplishing a purpose.[2][5][6] The spelling with -a- dates from the 15th century.[4] The noun meaning a seat across a boat is dated 1721 by the OED[7] and about 1736 by Barnhart and Merriam-Webster.[3][5]
