orthography

n. standard writing; art of writing words with the correct letters under standard usage; representation of sound of a language by written or printed symbols; study of spelling and writing

The orthography of a language specifies the correct way of using a specific writing system to write the language. (Where more than one writing system is used for a language, for example for Kurdish, there can be more than one orthography.) Orthography is derived from Greek ὀρθός orthós ("correct") and γράφειν gráphein ("to write"). Orthography is distinct from typography.
