course: [13] Etymologically, course denotes ‘running’. It comes via Old French cours from Latin cursus, a derivative of the verb currere ‘run’ (from which English gets current and a wide range of other words, from courier to occur). Its earliest meaning in English was ‘onward movement in a particular direction’, but over the centuries it has developed a network of additional senses.
From the same Latin base curs- are concourse [14], cursory [17] (from Latin cursōrius), discourse [14] (and the related discursive [16]), excursion [16], incursion [15], precursor [16], and recourse [14]. The derived noun courser [13] is a doublet of corsair. => corsair, courier, current, discourse, excursion, occur

late 13c., "onward movement," from Old French cors (12c.) "course; run, running; flow of a river," from Latin cursus "a running race or course," from curs- past participle stem of currere "to run" (see current (adj.)).
