Synonym discussion
Sense: noun/1
The three words all refer to the same body part but differ sharply in register and context. 'Belly button' is the everyday word — the one a parent says to a child, or a friend uses in casual conversation. 'Navel' sits in the middle: it is the standard neutral term in writing and is the word taught in school health classes. 'Umbilicus' is strictly medical or anatomical — you would only encounter it in a doctor's report, a biology textbook, or a clinical description. Choosing between them is mainly about context: 'belly button' for talking to a friend, 'navel' for a general article, and 'umbilicus' for a medical chart. For example: 'The baby's belly button is still sore' (casual), 'The incision was made just below the navel' (written record), 'The umbilicus showed signs of infection' (medical report).

Etymology
The word 'navel' comes from Old English 'nafela', which traces back to the Proto-Germanic root '*nabalô' and further to the Proto-Indo-European root '*h₃nóbʰōl', meaning 'navel' or 'hub of a wheel'. The connection between a navel and a wheel's hub is an ancient one — both are the central point around which something turns or grows. That same PIE root also gave rise to the Latin 'umbilicus' (navel) and, through a different path, the English word 'nave' (the central hub of a wheel). The figurative sense 'central point' emerged in English by the 14th century, modelled on this longstanding metaphor.
