“Incongruous is a spin-off of its antonym, congruous, which means ‘in agreement, harmony, or correspondence.’ Etymologists are in agreement about the origin of both words; they trace it to the Latin verb congruere, which means ‘to come together’ or ‘to agree.’ The dates of the words’ first uses in English match up pretty well, too. The first known use of congruous dates from 1599, and the earliest print appearance of incongruous dates from 1611.” – Merriam-Webster
