What is a trigraph?

What is a trigraph?

• A. A two-letter combination that creates one phoneme.
• B. A three-letter combination that creates one phoneme, such as 'dge' in 'badge'.
• C. A three-letter sequence that creates two phonemes.
• D. A three-letter pattern that yields a single phoneme.

Answer: (B)

A trigraph is a three-letter group that represents a single sound. In English, some three-letter clusters produce one phoneme, not three separate sounds. The example in a common word shows this clearly: the letters d-g-e together create the /dʒ/ sound (the same sound as "j") in badge. So the three letters are working as one unit to make one sound. This is why that option is the best: it names a three-letter sequence that yields a single phoneme, with a concrete example. The idea of two letters making one sound describes a digraph, which isn’t the focus here. And a three-letter sequence that makes two sounds isn’t how a trigraph is defined. While a three-letter pattern can produce a single sound in general, the strongest, most precise illustration is the three-letter cluster like “dge” producing one phoneme.
