  • The obligatory, meaningless use of do in interrogative, negative, and—formerly—affirmative sentences, which is unusual in Germanic languages, is thought by some linguists to be one of the Brittonicisms in English, calqued from Brythonic. It is first recorded in Middle English, where it may have marked the perfective aspect, though in some cases the meaning seems to be imperfective. In Early Modern English, any meaning in such contexts was lost, making it a dummy auxiliary, and soon thereafter its use became mandatory in most questions and negations.
  • From the name of musicologist Giovanni Battista Doni, who suggested replacing the original ut with an open syllable for ease of singing. First found in Italian.
