Etymology

Origin of cogent

1650–60; < Latin cōgent- (stem of cōgēns, present participle of cōgere to drive together, collect, compel), equivalent to cōg- ( co- co- + ag-, stem of agere to drive) + -ent- -ent

Explanation

When you make a cogent argument, it means your argument is clear and persuasive. In these days of 24-hour entertainment news and sound-bite sized explanations of complex government policy, it’s hard to find a cogent argument amidst all the emotional outbursts. Cogent comes from a Latin word meaning "to drive together," so cogent thinking is well-organized: it hangs together. If you try to convince your mayor to build a new park by saying that playgrounds are good, seeing the sky is nice, and raccoons are cool…well that’s not a cogent argument; it’s just random. But you could cogently argue that parks contribute to civic happiness by providing space for exercise, community, and encounters with nature.
