Etymology

Origin of impinge

First recorded in 1525–35; from Medieval Latin impingere “to strike against, drive at,” equivalent to Latin im- prefix meaning “in” ( see im- ¹) + -pingere, combining form of pangere “to fasten, drive in, fix”; see impact

Explanation

Whether you have a habit of standing too close when talking to others or bringing luggage on a crowded rush-hour subway car, you'll find people don't like it when you impinge on their personal space. When you impinge, you intrude on something, whether it’s someone else’s space, time, or rights. Think of it as moving in on someone’s territory. The word also can be used in the sense of affecting something, usually negatively, often by restricting it. For example, constantly inviting your friend to go shopping and meet you in nice restaurants might impinge on her desire to save money.
