Built from
From freak + -ish. freak comes from Middle English friken, from Old English frīcian. 1567. The sense "sudden change of mind, a whim" is of unknown origin. Probably from a dialectal word related to Middle English frekynge (“capricious behavior; whims”) and Middle English friken, frikien (“to move briskly or nimbly”), from Old English frīcian (“to leap, dance”), or Middle English frek (“insolent, daring”), from Old English frec (“desirous, greedy, eager, bold, daring”), from Proto-West Germanic frek, from Proto-Germanic frekaz, frakaz (“hard, efficient, greedy, bold, audacious”) (in which case, it would be related to the noun under a man). Compare Old High German freh (“eager”), Old English frēcne (“dangerous”). For the meaning development compare заско́к akin to ско́к, скака́ть.
