fledge (English)

Where does "fledge" come from?

The English verb 'fledge' descends from Middle English 'flegge'[1], which traces back to Old English '*flyċġe' meaning 'able to fly, fledged'[1]. This Old English term developed from Proto-West Germanic '*flugi', which derived from Proto-Germanic '*flugjaz'[1]. Ultimately, these Germanic terms stem from Proto-Indo-European '*plewk-' meaning 'to run, flow, be swift, flee, fly'[1].
