Fun Fact

Labile comes from the Latin labilis, meaning “slippery”—fitting for a word used to describe volatility. In neuroscience, labile emotions refer to intense mood swings, such as in bipolar disorder. In chemistry, it applies to bonds or compounds that shift states easily. The word is also increasingly used in pop psychology to describe people whose reactions change without warning.
