Etymologically, the entry records: From French éco-, from Latin oeco-, from Ancient Greek οἶκος (oîkos, “house, household”). Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear.
