Other forms: hindered; hinders; hindering
The verb hinder means to block or put something in the way of, so if you’re in a high-speed car chase with the police, they might put up a blockade to hinder your progress.
The word hinder came from the Old English hindrian, which means to "injure or damage." That's a little more extreme than what it means today, because, now it just means to get in the way of something or someone. People might not like you too much if you make it a practice to hinder their progress or get in the way of things they want, even if it's a small hindrance like blocking someone from getting to the cookie jar.
