Etymology

Noun

Middle English coordone "cord worn in token of victory," borrowed from Middle French cordon "small cord, bowstring," going back to Old French, from corde "rope, string" + -on, diminutive suffix (going back to Latin -ō, -ōn-, suffix of nouns denoting persons with a prominent feature) — more at cord entry 1

Note: The sense "alignment of objects" appears to have originated in French in the 17th century; the military use ("line of military posts," etc.) is attested in French in the 18th century not long before it first appeared in English.
