flow: [OE] The prehistoric Indo-European *pleu-, ancestor of a heterogeneous range of English vocabulary, from fleet to plover, denoted ‘flow, float’. It had a variant form *plō-, which passed into Germanic as *flō-. This formed the basis of the Old English verb flōwan (whence modern English flow) and also of the noun flood.

flow (v.)youdaoicibaDictYouDict
Old English flowan "to flow, stream, issue; become liquid, melt; abound, overflow" (class VII strong verb; past tense fleow, past participle flowen), from Proto-Germanic *flowan "to flow" (cognates: Middle Dutch vloyen, Dutch vloeien, vloeijen "to flow," Old Norse floa "to deluge," Old High German flouwen "to rinse, wash"), probably from PIE *pleu- "flow, float" (see pluvial). The weak form predominated from 14c., but strong past participle flown is occasionally attested through 18c. Related: Flowed; flowing.
