Phonemes

Phonemes are the individual sounds that make up a language. In English we have more than 40 phonemes, but we have only 26 letters. So, some phonemes are usually spelled using two letters working together,;this is called a digraph.
In English, most phonemes can be spelled more than one way. For example, the sound /ai/ can be spelled "ay" (pay), "a_e" (cake), "ai" (rain), "eigh" (neighbor), "ea" (break), and a few other ways.
The same spelling can also be used to represent more than one phoneme. For example, the spelling "ou" can be used to indicate the sounds /ow/ (loud), /u/ (touch), /ue/ (soup), /oa/ (shoulder), and /o/ (cough).
