Which term describes a sound that has two parts?

• A. short vowel
• B. blend
• C. diphthong
• D. digraph

Answer: (C)

A sound described as having two parts is a diphthong. A diphthong is a single vowel sound that starts in one position of the mouth and glides toward another within the same syllable, so you hear two vowel qualities in one smooth sound. Think of how the vowel sound in words like coin, go, or out moves from one vowel shape to another as you pronounce it. That movement is what makes it two-part. This differs from a short vowel, which stays as a single, pure vowel sound as in cat or sit. It also differs from a blend, which is about combining two or more consonant sounds into a cluster like bl or str. And it’s not about two letters making one sound—that idea is a digraph, where two letters work together to represent one sound, such as sh or ea in certain contexts. The emphasis for a diphthong is the vowel sound itself changing within the syllable, producing two parts in one syllable.
