Gregarious (gri-gair-ee-uh s) is an adjective that will likely mean “social” or “friendly”. Even when it doesn’t, it sort of does, because the other meaning of it is used to describe animals that live in groups. It’s a mid-17th century word coming from the Latin root “grex” or “greg“, meaning a flock.
I am not a particularly gregarious person; I can enjoy being in a group, but it greatly depends on the group, and sooner rather than later I will need to go be off by myself for a while to decompress. I do, however, like the way this word looks and sounds!
