A grapheme is a letter or a number of letters that represent a sound (phoneme) in a word. Another way to explain it is to say that a grapheme is a letter or letters that spell a sound in a word.
Some written scripts are simple in which 1 letter usually represents 1 sound. These letters and their corresponding sounds are consistent and transparent. For this reason languages like Italian or Spanish are easy to read. English has a complex code in which 1-4 letter graphemes can represent 1 sound.
Here is an example of a 1 letter grapheme: c a t. The sounds /k/ is represented by the letter ‘c’.
Here is an example of a 2 letter grapheme: l ea f. The sound /ee/ is represented by by the letters ‘e a’.
Here is a 3 letter grapheme: n igh t. The sound /ie/ is represented by the letters ‘i g h’.
Here is a 4 letter grapheme: th r ough. The sound /oo/ is represented by the letters ‘o u g h’.
And if that is not complicated enough think of this:
Some sounds (phonemes) can be spelled by different graphemes (spellings) e.g.:
-the sound /k/ can be spelled ‘c, k or ck’
-the sound /ee/ can be spelled ‘ee, ea, ie, ei, e, e-e, etc’
Some graphemes (spellings) can represent different sounds (phonemes) e.g. the letter can spell:
/a/ in ‘apple’
/o/ in ‘want’
/ar/ in ‘fast’
/ae/ in ‘table’
WHAT A HEADACHE!
