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.
