An Etymological Dictionary of the German Language/Annotated/Mahd
Mahd, feminine, ‘mowing, swath,’ from Middle High German mât (genitive mâdes), neuter (also feminine), ‘mowing, what has been mown, hay, meadow,’ Old High German mâd, neuter; hence Old High German mâdâri, Middle High German mâdœre, mœder, Modern High German Mähder, ‘mower’; Anglo-Saxon mœ̂þ, neuter, ‘mowing, what has been mown, hay,’ English math in aftermath and lattermath. High German Mahd, and English math, Gothic *mêþ (genitive *mêþis), are properly verbal abstracts of the root mê, ‘to mow,’ just as the cognate Greek ἄμητος, ‘harvest,’ is derived from ἁμάω, ‘I mow’; compare also ἀμητός, ‘crop, the field when reaped.’ See Grummet, Matte, and Omet. —
