Graphemes are the alphabet letters, or letter combinations, that represent a single sound in a written word.

An example of a single letter representing a single sound (a grapheme) can be seen in the following words: sat, pat and dog.

Some sounds are represented by two letters and are called digraphs such as the ‘ch’ in ‘chip’ or ‘sh’ in ‘shop’ or ‘ea’ in ‘head’ and the ‘ai’ in ‘rain’.

Other sounds can be represented by 3 (trigraphs) or 4 (quadgraph) letter combinations such as ‘igh’ in ‘light’ and ‘eigh’ in ‘eight’.
