What is the function of a consonant digraph?

A consonant digraph functions to represent a single sound using two letters. For example, in words like "ch," "sh," and "th," the combination of letters produces a distinct phoneme that cannot be solely attributed to either letter when pronounced individually. This unique representation allows for a broader range of sounds in the English language and helps learners understand that some sounds are constructed through the combination of specific letters rather than relying solely on individual letter sounds. Understanding how consonant digraphs work is crucial for developing reading and spelling skills, as they are foundational components in phonics instruction.

The other choices present different concepts not aligned with the specific function of consonant digraphs. Blending two consonants together refers to consonant blends, where both sounds can be heard distinctly. Creating a rhyme scheme pertains to the arrangement of end sounds in poetry and does not involve consonant digraphs. Indicating syllable breaks is related to syllable structure and division rather than the formation of a single sound with two letters.
