Etymology: "Obturations" is the plural of "obturation," a noun for the act of closing off an opening. The word comes from Latin "obturatio," which is built from "obturare," meaning "to stop up" or "to block," from "ob-" (against, in the way of) and "turare," to stuff or plug. The same stopping-up idea runs through the English word, whether the thing being sealed is a pipe, a wound, or a gap. Because "obturation" is a formal borrowing rather than a word that developed through everyday speech, its history is simply the Latin term carried into English, with French "obturation" offering a parallel route for the same sense. The plural form simply counts multiple acts or instances of such closing, as in technical contexts like the sealing of a gun breech or the closing of a passage in the body.
