Synonym Discussion of PLUMB

vertical, perpendicular, plumb mean being at right angles to a base line. vertical suggests a line or direction rising straight upward toward a zenith <the side of the cliff is almost vertical>. perpendicular may stress the straightness of a line making a right angle with any other line, not necessarily a horizontal one <the parallel bars are perpendicular to the support posts>. plumb stresses an exact verticality determined (as with a plumb line) by earth's gravity <make sure that the wall is plumb>.
