'Eastern-oriented' originates from English, specifically the words 'eastern' and 'oriented', where 'eastern' derives from Old English 'ēast' meaning 'east' and 'oriented' derives from Latin 'oriens' (from 'oriri') meaning 'rising' or 'the east'.

'Eastern' changed from Old English 'ēast' to Middle English 'east(e)rn', and 'orient' changed from Latin 'oriens' through Old French 'orient' to Middle English 'orient', eventually forming the modern compound 'Eastern-oriented'.

Initially, the component words meant 'east' and 'rising' (as of the sun); over time the compound evolved to mean 'directed toward or focused on the East' in geographic, cultural, or political contexts.
