Which term describes a single vowel sound?

• A. Diphthong
• B. Monophthong
• C. Schwa
• D. Utterance

Answer: (B)

The term for a single vowel sound is monophthong. A monophthong stays the same throughout articulation—a pure, unchanging vowel quality. In contrast, a diphthong changes quality while you pronounce it, gliding from one vowel sound to another within the same syllable, like the sounds in “coin” or “loud.” The schwa is a specific, neutral vowel sound (the relaxed “uh” heard in unstressed syllables such as in “about”), which is still a single vowel sound but not the general label for any single vowel sound. Utterance refers to spoken language in general, not to vowel quality.
