Usage

What does hamper mean? To hamper means to hold back or impede something or someone, as in The road crew hampered traffic, causing a line of cars that went back for miles. Figuratively, hamper can mean to interfere with or diminish, as in The singers practicing in the next room really hampered my ability to study. Related to this in nautical terms, a hamper is gear that is necessary but gets in the way. There is another sense of the noun hamper that comes from a different origin. This hamper is a large basket, often made of wicker (or something that looks like wicker) and having a cover. Most often, this type of hamper is associated with dirty clothes (a laundry or clothes hamper), but there are lots of things a hamper can hold, like a picnic lunch or small toys. Example: I hope this rain doesn’t end up hampering the party at all.
