'Eastern-style' originates from English, specifically the elements 'eastern' (from Old English 'ēast' + adjective-forming suffix '-ern') and 'style' (from Latin 'stilus' via Old French 'style'), where 'ēast' meant 'east' and Latin 'stilus' originally meant 'writing implement' or 'manner of writing'.

'Eastern' developed from Old English 'ēast' → Middle English 'easterne/estern' and became 'eastern' in Modern English; 'style' changed from Latin 'stilus' into Old French 'estile/style' and eventually Middle English 'stile/style', yielding the modern English 'style'; the compound 'Eastern-style' arose by combining the adjective and noun to describe a manner or design associated with the East.

Initially, the roots referred separately to 'east' and to a 'manner or way (originally of writing)'; over time, 'style' broadened to mean 'manner, design, or fashion', and the compound 'Eastern-style' came to mean 'manner or design typical of the East'.
