What does umbilical mean?
Umbilical is most often an adjective describing something connected with the navel or, more commonly in modern medicine, the umbilical cord. It may refer to the cord itself, its vessels, or the point where a fetus was attached to the placenta. In figurative use, an umbilical connection is the vital link that keeps a person, organization, or system supplied, supported, or in contact with its source; such a connection can be lifelike but may also suggest dependence or control. The noun umbilical is a concise, usually technical term for an umbilical cord, especially in descriptions of space missions and other equipment connected by a flexible line. Umbilical is valuable in reading because it moves easily between a literal biological context and a vivid metaphor for an indispensable connection. Its biological association is the foundation, while the figurative sense often implies that the connection is essential, delicate, or difficult to replace.

Where does umbilical come from?
Umbilical comes from the Latin adjective umbilicalis, meaning “of or relating to the navel,” which was formed from umbilicus, “navel.” The same Latin stem underlies English words such as umbilicus and umbilicate. English usage developed from the literal anatomical term, while the figurative meaning for an indispensable connecting link became established in ordinary language.
