The prefix Ton- denotes which concept?

The prefix Ton- denotes which concept?

• A. Color
• B. Stretch
• C. Tone
• D. Sound

Answer: (B)

Ton- signals tension and the state of being stretched under force. In medical terms, this root underlies ideas like muscle tone and the taut, ready-to-act condition of a muscle, which comes from stretch and tension in tissues. Because the other options point to color (color-related prefixes), sound (phon-, son-), or a musical sense of tone rather than a physical state of being stretched, the concept that best fits ton- is stretch. In practice, ton- describes the tension that keeps tissues taut, which aligns with the idea of them being stretched or held in that state.
