Marbles in your mouth where does it originate?

Answer 1

The phrase “marbles in your mouth” originates as a metaphor rather than a literal expression. It refers to the difficulty of speaking clearly, as if one’s mouth were filled with marbles. The origin is believed to come from public speaking and diction training in ancient Greece, where orators like Demosthenes were said to practice speaking with pebbles in their mouths to improve clarity and strength of speech. Over time, the phrase evolved to describe mumbled, unclear, or slurred speech in general.

Answer 2

The expression is Get the marbles out of your mouth, meaning Speak clearly, or Out with it!. The Greek orator Demosthenes is said to have overcome a speech impediment by speaking over the roar of the ocean with pebbles in his mouth.
