Etymology

Origin of influence

First recorded in 1325–75; Middle English, from Medieval Latin influentia “stellar emanation,” equivalent to Latin influent- ( influent ) + -ia -y ³; -ence

Explanation

Influence is the power to have an important effect on someone or something. If someone influences someone else, they are changing a person or thing in an indirect but important way. Sometimes a person who influences another doesn't intend to have any effect, but sometimes they are using influence to benefit themselves. An example of a personal benefit or advantage would be the use of political influence. Influence is also a verb, from Latin influere to flow in.
