What does mumble mean?
To mumble is to speak in a low, indistinct, or unclear way, often so that the listener has difficulty hearing or understanding the words. People may mumble because they are embarrassed, frightened, tired, or simply speaking quietly, and the word can carry a mildly dismissive or comic connotation when it describes habitual unintelligibility. A mumble may also refer to a vague or incomplete utterance that avoids giving a clear answer. In figurative use, the verb can mean to speak or communicate in a subdued, hesitant manner. Mumbling is distinct from merely whispering, since it emphasizes lack of clarity rather than volume alone. It is also different from stuttering, which is a speech pattern involving repeated or interrupted sounds, and from grumbling, which specifically expresses complaint.

Where does mumble come from?
The verb developed during the early modern period from a Middle English form meaning to speak unclearly or mutter. Its immediate source was probably Low German mummeln, a Germanic verb with cognates in Dutch mommelen, German mummeln, and Swedish mummla. The modern English word retained the basic sense of low or indistinct speech while also acquiring figurative meanings such as speaking vaguely or hesitantly.
