What does mumbled mean?
“Mumbled” is the past tense and past participle of “mumble,” meaning to speak so quietly or indistinctly that the words are difficult to hear or understand. It commonly describes speech delivered with a lowered voice, a closed mouth, or insufficient clarity, and it can carry a faintly critical or dismissive tone: a mumbled excuse may sound evasive, while a mumbled greeting can simply suggest private or absentminded speech. The word is usual in both British and American English and is especially natural in narration and dialogue. It can also work adjectivally before a noun, as in “a mumbled apology,” while “murmured” is often a close alternative when the emphasis is on speaking softly rather than failing to articulate clearly. “Mumbled” is useful because it captures both sound and social impression: what is said seems physically low or blurred, and its effect on the listener may be awkward, evasive, or hard to follow.
To speak in a low or indistinct voice so that the words are difficult to hear or understand.

Where does mumbled come from?
The verb entered English in the early modern period through forms such as Middle English “mumple.” It was probably borrowed from Middle Dutch “mompelen,” which had an older Dutch ancestor of imitative origin, resembling the sound produced by quietly moving the lips. English subsequently developed forms including “mumble,” “mumbler,” and “mumblingly.”
