Did you know?

For eons, humans have contrasted love with hate and good with evil, putting love and good on one side, and hate and evil on the other. The association of hate with evil is baked into the etymology of heinous, which English gained directly from Anglo-French in the 14th century with the meaning we still know today; its source is the Anglo-French noun haine, meaning “hate.” Haine in turn comes from a verb of Germanic origin, hair, also meaning “to hate.” (The similarity between this hair and the other hair is coincidental.) Chaucer’s poem “Troilus and Criseyde” provides an early example of heinous in English: “He rang them out a story like a bell, against her foe who was called Polyphete, so heinous that men might on it spit.”
