A digraph is a pair of letters that represent a single sound in a language It is used to represent different sounds from those represented by single letters. For instance, the letter ‘C’ usually makes a ‘k’ sound, but when it is paired with an ‘h’ it forms a ‘ch’ sound. Digraphs can also change the sound of a vowel. For example, a ‘e’ at the end of a word normally sounds like a short ‘e’, but with the addition of a ‘y’, it takes on a long ‘e’ sound.
Digraphs are sometimes used as spelling conventions in English to represent sounds that would otherwise take multiple letter combinations, such as ‘sh’ or ‘gh’. They are also used in other languages such as Spanish, German, French, and Arabic to represent unique sounds not found in English.
