Lair definition, a den or resting place of a wild animal: The cougar retired to its lair. See more.
A lair is a wild animal's den. If you ever find yourself in a forest and face to face with a bear trying to lure you into his lair, beware! He may be plotting to eat you. The noun lair has its roots in the Old English leger, meaning âbed, couch, place of lying down.â It eventually became an âanimalâs denâ in the early 15th century. A person can have a lair, too, like the photo-covered basement of a serial killer, or a less scary person might have a cozy lair lined with plush carpet. Always poke a stick into a lair before going in, because you never know what sort of beast is lurking inside.
