Etymology
The word 'umbilicus' entered English directly from Latin, where it meant 'navel' or 'middle point'. The Latin term itself is derived from the Proto-Indo-European root h₃nóbʰōl, also meaning 'navel', which is the source for similar words across many Indo-European languages, such as Greek omphalos. The semantic journey is remarkably direct, with the core concept of a central, connecting point remaining intact. In English, it retains its precise anatomical meaning while also being used metaphorically to denote any central or focal hub.
