Grammar
Two letters written together to represent a single sound. For example, these are consonant digraphs:ch ck gh ph sh th There are also many vowel digraphs in English. For example:ai au ea ei oa oi ou For historical reasons, the letters ‘a’ and ‘e’ are frequently joined in the older spelling of words such as medieval:mediæval The use of this digraph is, however, dying out.
