syllable, or speech unit). In Sanskrit, it denotes something that is unable

to be spoken, dumb, mute, or unlettered. It can also refer to blameable

or improper speech, including words that are abusive or unsuitable

to utter

or “mute”, and as an adverb, it denotes acting without words or 

speechlessly. In Sanskrit phonetic and grammatical analysis, the term

is also associated with sounds that cannot be articulated as ordinary

letters or syllables
