Etymology
The word 'round' entered English from Old French 'rond', meaning 'round, spherical, circular'. The Old French term derived from the Latin adjective 'rotundus', sharing the same meaning. 'Rotundus' itself is a derivative of the Latin noun 'rota', meaning 'wheel', which can be traced back to the Proto-Indo-European root ret-, meaning 'to run, to roll'. The semantic journey is clear: from the concept of rolling (a wheel) to the shape of a wheel (circular, spherical), and finally to the generalized modern meanings describing circular shape, completeness, or a recurring cycle.
Analysis
The word 'round' is a simplex word of Old French origin, ultimately from Latin. It cannot be meaningfully segmented into smaller morphemes within its current English spelling.
