'circular-patterned' originates from English, formed by combining 'circular' (from Latin 'circulus' meaning 'small ring') and 'patterned' (from 'pattern', ultimately from Old French 'patron'/'patron' via Medieval Latin and Latin roots related to 'model' or 'pattern').

'circular' comes from Latin 'circulus' → Late Latin 'circularis' → Middle English 'circular'; 'pattern' developed from Old French 'patron'/'patron' → Anglo-Norman/Middle English 'pattern', and the past-participial adjective 'patterned' was formed in modern English by adding -ed to 'pattern'. These elements were later combined as a compound adjective 'circular-patterned'.

Individually, 'circular' originally meant 'of or pertaining to a circle' and 'pattern' meant 'a model or repeated decorative design'; combined as 'circular-patterned' the phrase specifically describes something that bears a repeated circular design.
