mussitation
mus·si·ta·tion
noun
a low continuous indistinct sound; often accompanied by movement of the lips without the production of articulate speech
Origin
Learned borrowing from Latin mussitātiō (“soft noise made by dogs, or (Late Latin) people”) + English -ion (suffix denoting a condition or state). Mussitātiō is derived from mussitātus (“kept quiet; having been kept quiet; murmured, muttered; having been muttered”) (see further at mussitate) + -iō (suffix forming abstract nouns from verbs).
