Frequently asked questions

What is the difference between a non sequitur and a red herring?

A non sequitur simply fails to connect: the conclusion or reply does not follow from what preceded it, usually through muddle. A red herring is deliberate — an irrelevance introduced to draw attention away from the real question.

How do you pronounce non sequitur?

Most English speakers say non SEK-wi-ter, stressing the second syllable of sequitur. A classical Latin pronunciation would be non SEK-wi-toor, but that is rare in English conversation.

Is non sequitur hyphenated or italicised?

It is written as two words with no hyphen, and it is now naturalised enough in English that italics are unnecessary. The plural is non sequiturs.

What is the meaning of non sequitur?

"non sequitur" (noun) means a statement or reply that does not follow logically from what came before, so that the connection is missing or absurd.
