Where this word comes from
Etymology tree Proto-Indo-European *bʰel-der. Proto-Indo-European *bʰlewH-der. Proto-Indo-European *bʰluH-yé-ti? Latin fluō Ultimately from Proto-Indo-European *bʰlewH- (“to overflow”), possibly an extension of *bʰleh₁- (“to swell, blow”). The Latin form may have developed from earlier *flowō via vowel reduction (which was regular only in non-initial syllables, but may have been introduced to the simple verb by analogy with its compounds) from Proto-Indo-European *bʰleuH-(e/o). Alternatively, it may go back to Proto-Italic *flūō, from earlier *flūjō, from Proto-Indo-European *bʰluH-yé-ti. Cognate with Ancient Greek φλέω (phléō, “to abound”), φλύω (phlúō, “to boil over”). Unrelated to English flow, despite phonological and semantic similarity.
