alphabet

ABCs redirects here, for the Alien Big Cats, see British big cats. An alphabet is a standardized set of letters — basic written symbols — each of which roughly represents a  phoneme of a spoken language, either as it exists now or as it was in the past. There are other systems of writing such as logographs, in which each character represents a word, and syllabaries, in which each character represents a syllable, but alphabets are the most widespread writing system.
