a cause of difficulty and suffering; "war is hell"; "go to blazes"
any place of pain and turmoil; "the hell of battle"; "the inferno of the engine room"; "when you're alone Christmas is the pits";
the state of being imprisoned; "he was held in captivity until he died"; "the imprisonment of captured soldiers"; "his ignominious incarceration in the local jail"; "he practiced the immurement of his enemies in the castle dungeon"
