Non sequitur (/nɒn ˈsɛkwɪtə/) is a Latin phrase that literally means "it does not follow." The spelling of this word follows a common Latin-based spelling convention, with "non" meaning "not" and "sequitur" meaning "it follows." This phrase is a logical fallacy that occurs when a statement or conclusion does not logically follow from the previous statement or evidence. In other words, it is a statement that is unrelated or irrelevant to the topic at hand.
A non sequitur is a term originating from Latin that refers to a statement or conclusion in an argument that does not logically follow from the previous premise or evidence provided. It is a logical fallacy that lacks coherence and fails to establish a logical connection between ideas. The phrase can also be used to describe a comment or remark that is unrelated or irrelevant to the ongoing conversation or context.
In formal logic, a non sequitur occurs when the conclusion drawn from the premises of an argument is not supported by the premises themselves. It includes statements that may be true or false individually but fail to contribute to the logical flow and coherence of the argument. Non sequiturs can often be misleading or distracting, hindering effective communication and critical thinking.
Commonly used in casual conversations, non sequiturs are characterized by their sudden, unexpected, and illogical nature. They derail the logical progression of discussion and can confuse listeners or readers, as they often lack a clear connection to the preceding conversation or topic. Non sequiturs can be intentionally employed for comedic effect to create surprise or to deliberately confuse the audience.
Overall, a non sequitur is a faulty statement or reasoning that disrupts the logical coherence of an argument or discussion by introducing an unrelated or irrelevant idea, lacking the necessary logical connection or coherence to support the preceding premises or context.
In logic, a term applied to an inference which does not follow from the premises.

The word "non sequitur" has its origins in Latin. "Non" means "not" or "no", and "sequitur" is the third person singular present indicative form of the Latin verb "sequi", meaning "to follow". Therefore, "non sequitur" literally translates to "it does not follow" or "it does not follow logically". The term was originally used in logic to refer to a conclusion that does not logically follow from the previous statement or argument. Over time, it has also come to be used more broadly to describe any statement or response that is disconnected from what preceded it.
