Word History

Etymology

Noun

Middle English cours, borrowed from Anglo-French cours, curs, going back to Latin cursus "action of running, charge, movement along a path, progress," from currere "to run, flow" + -tus, suffix of verbal action — more at current entry 1

Note: As pointed out by Michiel de Vaan (Etymological Dictionary of Latin and the Other Italic Languages, Leiden, 2008), the expected outcome of the verbal adjective in *-to- and the verbal noun in *-tū- would be *kostus < *korstus < *kr̥s-to-, kr̥s-tū-, from the verbal base *kr̥s- (> currere). The attested form cursus for both the past participle and verbal noun reflects remodeling on the pattern of stems ending in a dental (as morsus from mordere "to bite," versus from vertere "to turn"). As generally in Latin, the verbal noun, where full grade of the root would be expected, has been supplanted by zero grade of the verbal adjective.

Verb

Middle English coursen "to pursue," derivative of cours course entry 1
