Word History

Etymology

Noun

Middle English, "continuous sound, complaint," borrowed from Anglo-French murmure (also continental Old French), probably noun derivative of murmurer "to murmur entry 2"

Verb

Middle English murmuren "to hum (of bees), growl, grumble, complain," borrowed from Anglo-French & Latin; Anglo-French murmurer "to grumble, complain" (Old French also "to murmur" [of a brook]), borrowed from Latin murmurāre "to make a low, continuous sound, mutter, grumble, complain," of onomatopoeic origin

Note: Alternatively the medieval French word could be descended from murmurāre if the onomatopoeic character of the word would override the regular vowel change of ŭ to ọ; this is the opinion of the Französisches etymologisches Wörterbuch.
