It originated as a verb, Vulgar Latin *compassāre ‘pace out’, a compound formed from the Latin intensive prefix com- and passus (source of English pace). This passed into Old French as compasser ‘measure’, and thence into English. The derived Old French noun compas was early applied to a pivoted two-armed measuring and drawing instrument, presumably inspired equally by the ideas ‘stepping’ and ‘measuring’, and English acquired this sense in the 14th century.The use of the word for a magnetic direction indicator, which dates from the 16th century, may be due to the device’s circular container.=> pacecompass (n.)c. 1300, "space, area, extent, circumference," from Old French compas "circle, radius, pair of compasses" (12c.), from compasser "to go around, measure, divide equally," from Vulgar Latin *compassare "to pace out" (source of Italian compassare, Spanish compasar), from Latin com- "together" (see com-) + passus "a step" (see pace (n.)). The mathematical instrument so called from mid-14c. The mariners' directional tool (so called since early 15c.) took the name, perhaps, because it's round and has a point like the mathematical instrument. The word is in most European languages, with a mathematical sense in Romance, a nautical sense in Germanic, and both in English.compass (v.)c. 1300, "to devise, plan;" early 14c. as "to surround, contain, envelop, enclose;" from Anglo-French cumpasser, from compass (n.).
