Etymology: "Prograding" is the present participle of "prograde," a verb meaning to build land outward toward the sea. The word is formed from "pro-", meaning "forward," and "-grade," from Latin "gradus," meaning "step" or "degree," so the core image is a shoreline taking steps seaward. Its roots reach back through Latin "pro" to ancient Indo-European forms, which share the sense of "before" or "forward." The "-grade" element is the more useful clue to the word's making. It appears in many scientific and technical coinages where it denotes movement or direction, as in "retrograde," which moves backward. "Prograde" follows that same pattern, pairing "forward" with the idea of stepping, so a prograding coastline is one that advances step by step over time.
