Etymology: "Osteoclasts" is the plural of "osteoclast," and the plural form is the only one the system needs to explain. The singular is built from two Greek elements: "osteo-," from "osteon," meaning "bone," and "-clast," from "klastos," meaning "broken" or "broken in pieces," which comes from the verb "klan," to break. The name is thus literally a "bone-breaker," a fitting label for a cell whose job is to dissolve bone tissue. The Greek roots are ancient, but the compound itself is a modern scientific coinage, formed from them in the same way that many anatomical and medical terms were built in the nineteenth and twentieth centuries. Ancient Greek speakers had no word for the cell, since its function was not understood until modern microscopy and bone biology developed. The "-clast" element appears in related scientific terms such as "osteoclasis" and "iconoclast," the last of which joins it to "eikon," meaning "image," to describe a breaker of sacred images.
