Etymology
Origin of expectancy
From the Medieval Latin word ex(s)pectantia, dating back to 1590–1600. See expectant, -ancy
Explanation
Expectancy is the state of thinking (or hoping) that something will happen. You can sense the expectancy in the crowd just before your favorite band takes the stage. Use this word to talk about a sense of anticipation, like your little brother's expectancy every year on his birthday that someone will throw him a surprise party. It's also used to mean "an expected amount," especially in the context of life expectancy, or the average length of a person's life: "Typically, women have a longer life expectancy than men do." Expectancy is from expect, from a Latin root meaning "look for."
