Etymology

From Middle English decade, from Old French decade, from Late Latin decādem (“(set of) ten”), from Ancient Greek δεκάς (dekás), from δέκα (déka, “ten”). In reference to a span of ten years, originally a clipping of the phrase decade of years. By surface analysis, dec- + -ade. Doublet of decad and dekad.
