So here is something more stupid for you.Brier Rose said:This is so stupid.![]()
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>.
