'arabesquerie' originates from French, specifically the word 'arabesquerie', formed from 'arabesque' + the suffix '-erie' meaning a style, practice, or collection.

'arabesque' entered English via French from Italian 'arabesco' (meaning 'in the Arabic style'), which in turn traces to Medieval Latin and ultimately from 'Arab' (referring to Arabic-derived decorative motifs); the French noun 'arabesquerie' developed to mean the practice or style of such ornament and was borrowed into English in the modern period.

Initially it referred specifically to decorative motifs inspired by Arabic/Islamic art ('in the Arabic style'), but over time it broadened to denote any elaborate, interlaced ornamental design and, figuratively, excessive ornamentation.
