A digraph or digram (from the Greek: Î´Î¯Ï dÃ­s, double and Î³ÏÎ¬ÏÏ grÃ¡phÅ, to write) is a pair of characters used in the orthography of a language to write either a single phoneme (distinct sound), or a sequence of phonemes that does not correspond to the normal values of the two characters combined.
A consonant digraph consists of two adjacent consonants that produce one sound. The digraphs sh, ch, and th represent unique sounds that are not usually associated with any individual letters of the alphabet. The digraphs kn and gn are associated with the sound of /n/, and the digraph ph is associated with the sound of /f/. Learning to recognize the consonant digraphs is very helpful to beginning readers and writers because many early reading words contain these special two letter combinations.
