ins and outs, the

All the intricacies or ramifications of a situation. Originally this term referred to those in favor and those out of it, and then to those in or out of political office. As Chaucer put it in Troilus and Criseyde, “Weep if thou wolt, for out of doute, this Diomede is inne, and thou art oute.” Years later Thomas Jefferson (Writings, ca. 1814) similarly referred to “two parties, the ins and the outs.” Only in the nineteenth century did the term come to mean intricacies, referring to the windings and turnings of a complicated path or passage. Thomas Hood so used it in a late poem (“Laying Down the Law,” 1845): “The celebrated judge, too prone to tarry, to hesitate on devious ins and outs.”
