The Surprising History of Influence and Its Modern Use

Influence may seem like a ho-hum word, but its history is heavenly.

The word first referred to a celestial fluid that was believed to flow from the stars. As this fluid reached the Earth, it supposedly affected the actions of the planet's inhabitants—especially the human ones. (The word influenza has the same origin: the Medieval Latin word influentia. It was for a time believed that epidemics were caused by unusual conjunctions of the planets.)

In modern use, the noun typically refers to the power to change or affect someone or something—especially the power to cause changes without directly forcing those changes to happen. Influence can also refer to a person or thing that affects someone or something in an important way.

The noun had been in use for more than 200 years before the verb use developed. As a verb, influence typically means "to affect or change someone or something in an indirect but usually important way." Something or someone that influences a person or thing, then, has an influence on that person or thing.
