Which term describes two letters that together make one vowel sound?

• A. Digraph
• B. Grapheme
• C. Phoneme
• D. Vowel digraph

Answer: (D)

When two letters together produce a single vowel sound, that is a vowel digraph. This term specifically labels the situation where the vowel sound is created by a pair of letters working as one sound, as in “oa” in boat (the long o sound) or “ea” in bread (the vowel sound /ɛ/). The broader term digraph covers two letters that make one sound in general, but it isn’t limited to vowels—it also includes consonant pairs like “sh” or “ch.” A grapheme is the written symbol itself, which can be a single letter or a combination, but it doesn’t by itself specify that two letters share one vowel sound. A phoneme is the actual sound used in speech, not the written form. So the exact description for two letters forming one vowel sound is vowel digraph.
