humorless

the word 'humorless' is a modern english compound formed by adding the native english suffix '-less' to the noun 'humor'. the noun 'humor' has a fascinating journey, originating from latin 'humor' (moisture, fluid), reflecting the ancient and medieval physiological theory that four bodily fluids (humors) determined a person's temperament and health. by the 16th century, 'humor' evolved to mean 'state of mind, mood' (especially an odd or capricious one), which later narrowed to the sense of 'amusing quality' or 'comic perception'. therefore, 'humorless' literally means 'devoid of the quality of amusement', describing someone who lacks the capacity for comic perception or mirth, a meaning fully abstracted from its ancient roots in fluidic physiology.

Structure: humor + less humor: from latin 'humor' meaning 'moisture, fluid', later 'bodily fluid' and 'temper, mood'. in this word, it functions as the base noun meaning 'the quality of being amusing'. less: from old english '-lēas', meaning 'devoid of, free from'. it functions as a suffix forming adjectives meaning 'without'.
