词源

From Middle English septenarie, septenary, from Classical Latin septēnārius (“consisting of seven each”), from septēnus (“seven each; seven at a time”) + -ārius (whence the English suffix -ary). With use as noun compare septēnārius (“line of seven feet; unit of seven parts; period of seven years”). By surface analysis, septen- + -ary. Doublet of septenar and septenarius.
