Accli'vity. n.s. [from acclivus, Lat.] The steepness or slope of a line inclining to the horizon, reckoned upwards; as, the ascent of an hill is the acclivity, the descent is the declivity. Quincy.

The men, leaving their wives and younger children below, do, not without some difficulty, clamber up the acclivities, dragging their kine with them, where they feed them, and milk them, and make butter and cheese, and do all the dairy-work. Ray on the Creation.
