Etymology: Microcephaly is built from two Greek elements: "mikros," meaning small, and "kephalē," meaning head, joined through the combining form "-cephaly," which gives the sense of having a head of a particular kind. Its literal meaning is "smallness of head," and the term describes a medical condition in which the skull, and so the brain inside it, is markedly smaller than expected for a person's age and sex. The "micro-" element is the same one found in "microscope" and "microbe," where it likewise means small. The "-cephaly" element comes from "kephalē" and appears in many medical terms, such as "brachycephaly" for a broad, short skull and "dolichocephaly" for a long, narrow one. Because these terms were built from classical Greek parts, they are modern scientific coinages rather than words the ancient Greeks themselves used for this condition.
