Not all writing systems represent language in this way: a syllabary assigns symbols to spoken syllables, while logographic systems assign symbols to spoken words, morphemes, or other semantic units. Specifically, letters correspond to phonemes, the categories of sounds that can distinguish one word from another in a given language. For other uses, see Alphabet (disambiguation).Īn alphabet is a standardized set of written letters that represent particular spoken sounds in a language.
