from From Latin 'umbilicalis,' relating to 'umbilicus' — the navel, which itself traces back to an ancient Indo-European root for 'navel' shared across many languages (think Greek 'omphalos'). The word simply marks the spot where the cord once attached; 'cord' arrives separately from Latin 'chorda,' meaning string or rope, via Greek 'khorde,' originally gut or lyre-string. Put together in English by the 1700s to name the biological lifeline anatomists had long observed but only then systematically labeled.
