Etymology: "Triploidies" is simply the plural of "triploidy," so it describes more than one case of a cell or organism carrying three full sets of chromosomes. The base word is built from "triploid," which combines "tri-," from Greek and Latin "tri-" meaning "three," with "-ploid," a scientific element from Greek "-ploos," meaning "-fold," and the suffix "-y," which turns the adjective into a noun for a state or condition. The most useful way to read the word is by its parts: "tri" for three, "ploid" for sets of chromosomes, and "-y" for the condition itself. Because "triploid" is a modern technical coinage built from classical building blocks, it has no ancient usage; the plural simply follows regular English noun formation.
