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.
Digraphs are graphemes spelled with more than one letter, usually two. We need many digraphs because English has more phonemes (42) than letters (26). Our most popular consonant digraphs in English involve the letter h: ch, ph, sh, and th. Other digraphs have silent letters, for example, kn, wr, and ck.
