adjust

At first glance, adjust looks like a neat little Latin package: ad- plus just, as though something is being made “just right.” That is probably not the whole story. The leading trail runs through Latin iuxta, “next to,” into Late Latin adiuxtare, “to bring near,” and then Old French ajuster, where fitting pieces together could mean calibrating or regulating them. Medieval English picked up ajusten in the late fourteenth century, while the familiar “just” shape helped pull the word toward ideas of correctness and fairness—a classic case of folk etymology quietly editing a word’s appearance. The older family is crowded with surprising relatives: iuxta gives us juxtapose, while iustus stands behind justice, jury, and justify. So when you adjust a camera lens, you are performing a tiny linguistic drama: bringing things near, fitting them together, and making them “just” right—even if Latin itself never quite assembled the word in that tidy modern way.
