Etymology: Dicephalic describes a body with two heads joined to a single torso, a condition most often seen in conjoined twins or in rare developmental anomalies. The Greek element "di-" means "two," and "cephalic" comes from Greek "kephalē," "head," so the word is a plain compound: "two-headed." Its formation follows the pattern of many medical and zoological terms built from Greek roots, which were assembled deliberately in scientific writing rather than passed down from ancient speech. The "cephalic" part carries more than one meaning in English. Its root gives us words for the head in anatomy, as in "cephalic vein," while "cephalopod," the group of molluscs such as squid and octopus, shares the same Greek stem and refers to animals whose feet grow around the head. Dicephalic, then, sits in a family of Greek-based terms that describe the head and its number or arrangement.
