Incite is a verb meaning "to move to action." It is often seen in the contexts of starting a riot or revolution. Insight, on the other hand, is a noun referring to the act or result of looking at something closely in order to learn truths about it. Incite also has the pronunciation stressed on the second syllable, while insight is stressed on the first.

Incite derives via Middle French from the Latin incitare, combining the in ("within") with citare, a verb meaning "to put in motion." Switching the prefixes gives us excite and recite. Citare also gives us the verb cite itself along with the related noun citation.

How to Use 'Insight'

Insight is a noun defined as "the power or act of seeing into a situation : penetration" and "the act or result of apprehending the inner nature of things or of seeing intuitively." Essentially, it's the effort to learn the truth about something by looking at it very closely.

It can be used as a count noun or mass noun:
