Spinster, a terme, or an addition in our Common Law, onely added in Obligations, Euidences, and Writings, vnto maids vnmarried. [John Minsheu, "Ductor in Linguas," 1617]Strictly in reference to those who spin, spinster also was used of both sexes (compare webster, baxter, brewster) and so a double-feminine form emerged, spinstress "a female spinner" (1640s), which by 1716 also was being used for "maiden lady."
