grounded is an adjective. It describes the state of a person/thing. It comes from the noun 'ground', meaning surface we walk on; idiomatic expression comes from pilot-ese: To ground a plane (i.e., the plane stays on the 'ground', close to the airport.)Originally Posted by Antonio
If a person is grounded, usually a teenager, it means, they a) can't leave their room or b) can't leave the house. They are not allowed to roam freely about the planet, sort to speak. They are grounded.
