*A phoneme is an atom of pronounced language.

*A grapheme is an atom of written language.

* In typography, a grapheme is the atomic unit in written language. Graphemes include letters, Chinese characters, Japanese characters, numerals, punctuation marks, and other glyphs.

* In a phonological orthography, a grapheme corresponds to one phoneme.

In English — multiple graphemes may represent a single phoneme.

For example, the word ship contains four graphemes (s, h, i, and p) but only three phonemes, because sh is a

digraph.

In English, the main

graphemes are the

twenty-six units that

make up the

alphabet.

Other graphemes include the

various marks of punctuation:

<.>, <;>, etc., and such special

symbols as <@>, <&>, and

*There are about 40 distinctive phonemes in English, but 70 letters or letter combinations to symbolize phonemes.

*This makes pronouncing spellings easier than writing correct spellings.
