     Ralph Wiggum is generally employed as a bottomless fount of glorious non sequiturs, but in “I Love Lisa” he stands in for every oblivious chump who ever deluded himself into thinking that with persistence, determination, and a pure heart he can win the girl of his dreams.

4. (comedy) A kind of pun that uses a change of word, subject, or meaning to make a joke of the listener’s expectation.

Usage notes

• The legitimate plural forms of non sequitur include the Anglicised non sequiturs and the Classical non sequuntur; non sequituri is also attested, but is rare, non-standard, and misformed.

• In sense “abrupt transition”, contrast with segue (“move smoothly from one subject to another”), which is etymologically opposite (“does not follow” vs. “follow”). However, segue has connotations of moving between distinct subjects, and thus to segue often means to change rather abruptly, with at best a pretense of smooth transition – in both cases there is often a rapid move between distinct subjects, with the distinction being whether this is done smoothly or not.

   • 2005, Tomasz P[iotr]. Terlikowski, “W poszukiwaniu Absolutu”, in Ozon, number 22, Warszawa:

     Moim zdaniem jest to jednak błąd non sequitur [polega on na tym, że wniosek nie wypływa logicznie z przesłanek — nawet jeśli są one prawdziwe — przyp. red.]: równość w wymiarze eschatologicznym nie może być uzasadnieniem równości ekonomicznej.

     In my opinion however it is a non sequitur error [it means, that a conclusion does not logically result from premises — even if they are real — editor's note]: equality in the eschatological dimension cannot be the justification of the economic dimension.
