Etymology

The word traces back to the ancient concept of the "four humors" (blood, phlegm, black bile, yellow bile), which were thought to govern health and personality. A balanced mix produced a cheerful temperament, linking "humour" to amusement by the 16th century. The spelling retained the French -our ending, though American English later simplified it to -or.
