Which definition describes a consonant digraph?

• A. The final silent e rule
• B. A final separate syllable containing a consonant followed by le
• C. Groups of two consonants that form consonant sounds...th, sh, che
• D. A group of two consonants that blend to make a sound

Answer: (C)

A consonant digraph is when two consonant letters work together to produce a single sound. That’s why describing it as two consonants that form one sound, with examples like th, sh, and ch, is the best fit. The other ideas describe different spelling patterns: a final silent e rule concerns how an e at the end changes the preceding vowel’s sound, not two consonants making one sound; a final separate syllable with le refers to a syllable structure rather than a letter-pair sound; and a group of two consonants that blend to make a sound describes blends, where each letter keeps its own sound rather than creating one new sound.
