'circularly-arranged' originates from the Latin word 'circulus,' meaning 'small ring,' and the Old French word 'arranger,' meaning 'to arrange.'

'circulus' transformed into the Old French word 'cercle,' and eventually became the modern English word 'circular.' 'Arranger' evolved into the modern English word 'arrange.'

Initially, 'circularly-arranged' meant 'arranged in a small ring,' but over time it evolved into its current meaning of 'organized in a circular pattern.'
