Etymology

Origin of group

First recorded in 1665–75; from French groupe, from Italian gruppo, ultimately from Germanic

Explanation

A group is an organization of people or things, like a reading group at a public library that holds book discussions every month. Group comes from the word for lump, or cluster. If you're out walking at night and see a group of wild dogs coming at you, best to go the other way. You could always find a group of people to walk with if you don't want to be alone. Group can also be used as a verb. If you're painting a still life, you might collect a bunch of objects from your house and group them together in an eye-pleasing arrangement.
