Tar
Definition:
(n.) A sailor; a seaman.
(n.) A thick, black, viscous liquid obtained by the distillation of wood, coal, etc., and having a varied composition according to the temperature and material employed in obtaining it.
(v. t.) To smear with tar, or as with tar; as, to tar ropes; to tar cloth.
