語源
英語の原文（Wiktionary）
The sense "sudden change of mind, a whim" is of uncertain 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 etymology 3). Compare Old High German freh (“eager”), Old English frēcne (“dangerous”).
