Latin nōn sequitur, it does not follow : nōn, not + sequitur, third person sing. present tense of sequī, to follow.(American Heritage® Dictionary of the English Language, Fourth Edition)
From the Latin phrase nōn sequitur ("it does not follow"), from nōn ("not") + sequitur (third-person form of sequor ("I follow")); in Latin, the phrase sees no use as a noun. Compare sequence, from same root. (Wiktionary)
