A cogent argument is one that really drives its point home because it is clear, coherent, and readily understandable, and perhaps also because of the etymological history of cogent. Cogent comes from the Latin verb cōgere, meaning “to drive or force together.” Something described as cogent fuses thoughts and ideas into a meaningful whole that others can readily grasp and accept. A cogent explanation is a convincing one, and cogent analysis has us nodding along because it is clear and pertinent. Cōgere was formed in Latin by combining the prefix co- with the verb agere, “to drive, lead, or act,” a root which is also the source of our familiar noun agent. Handily enough, one definition of agent is “a means or instrument by which a guiding intelligence achieves a result.” It follows logically then that cogency is often a worthwhile agent, indeed.
