What term describes two vowels in a single syllable where both sounds are heard?

• A. Diphthongs
• B. Morphemes
• C. Encode
• D. Justified Print

Answer: (A)

Two vowels in one syllable where you hear both sounds describes a diphthong. A diphthong occurs when the vowel sound glides from one quality to another within the same syllable, so you hear the two sounds as you say the word. This is different from a monophthong, where the vowel stays as one steady sound throughout the syllable. For example, in words like coin or loud, the vowel sound moves from one vowel quality to another, producing a blended, single-syllable vowel sound. The other terms don’t describe vowel sounds: morphemes are units of meaning, encode means to convert information, and justified print isn’t a linguistic term.
