Saturnine

Can the language you speak affect your mood? One American researcher says it can indeed, and that the prevalence of the “umlaut” in German makes them grumpy and saturnine. While pronouncing English vowels like “e” and “ah” create smile-like facial expressions, the umlaut requires the speaker to turn down the mouth in a sort of frown, which may induce sadness.

Saturnine (pronounced “SAT-ər-nine”)

Having a gloomy or bitter temperament.

Synonyms

dour, morose, taciturn, phlegmatic
