Smaller tents may be either free-standing or attached to the ground, but large tents are usually anchored by guy ropes tied to stakes.
(3) Tent (dating from 1300): "a portable shelter of skins or cloths stretched over poles". This in turn came from the Latin "tentus" (stretched), like hides stretched over a framework. The verb "to tent" meaning "to camp in a tent" dates from 1856.
