Did you know?

Congruous had only been part of the English language for a few decades in 1615, when a book about the Church of Rome referred to “teaching most congruous to reason.” The word has remained more or less true to its Latin roots: it comes from Latin congruus, an adjective that comes from the verb congruere, meaning “to come together” or “to agree.” (Its more common antonym, incongruous is about the same age.) Another familiar congruere descendant in English is congruent, which first appeared at least a century earlier with the same meaning as congruous. English also acquired congrue, a verb meaning “to be in harmony” or “to agree,” from congruere, but it has since become obsolete.
