The story
- Proto-West Germanic · derived from*harjatogō
- Old English · derived fromheretoga
- Middle English · derived fromheretogh
- English todayheretog
From Middle English heretogh, heretoȝe, from Old English heretoga, heretoha (“commander, general”), from Proto-West Germanic *harjatogō, equivalent to here (“army”) + tog. Doublet of heretoga (borrowed from Old English) and herzog (borrowed from the German cognate Herzog (“duke”)). The form likely did not naturally survive in daily use (an expected descendant from dialect may be *heretow), but was revived by scholars.
