A variant or archaic form of bemurmur; a murmuring sound or utterance.
An alternate spelling of 'bemurmur', likely from Middle English when spelling was not standardized and both forms coexisted in different regions or texts.
The '-ure' ending (from Latin '-ura') was sometimes added to verbs to create nouns, so 'bemurmure' might have been used as a noun meaning 'the act of murmuring'—showing how flexible Middle English spelling and word formation were.
