patterned

The word 'patterned' is built upon the noun 'pattern', which entered English in the 14th century from the Old French 'patron', meaning a patron, protector, or model. The French term derived from the Latin 'patronus', itself from 'pater' (father), implying a father-like guardian or exemplar. Over centuries, the meaning of 'patron/pattern' in English specialized from a person who serves as a model to an abstract design or guide used in artistic and technical work. The addition of the adjectival suffix '-ed', of ancient Germanic lineage, transforms this noun into an adjective, describing something that possesses or has been furnished with such a design or that conforms to a prescribed model. Thus, the modern term elegantly connects the ancient concept of a paternal exemplar to the contemporary ideas of decorative arrangement and standardized form.
