An Etymological Dictionary of the German Language/Annotated/Einöde
Einöde, feminine, from the equivalent Middle High German einœde, einœte, einôte, feminine, ‘solitude, desert,’ Old High German einôti, neuter, ‘solitude, desert.’ By being based on öde, the Middle High German and Modern High German word received its present form; properly, however, -ôti in the Old High German word is a suffix (compare Heimat, Monat, Armut); Gothic *ainôdus (compare mannisk-ôdus, ‘benevolence’) is wanting; compare Anglo-Saxon ânad (from ânôd), Old Saxon ênôdi, ‘desert’; the suffix -ôdus corresponds to Latin -âtus (senatus, magistratus). —
