Etymology

The word "compass" originates from Latin com- (together) + passus (step, pace). Initially, it referred to "a measured space or circle" (via the idea of "stepping together" to form a boundary). By the 14th century, it evolved to denote the navigational tool that "encircles" directions (from the concept of a circular dial). The verb form ("to encircle" or "to achieve") reflects the original Latin roots of encompassing or attaining through measured steps.
