Definition
In metal typesetting, a sort is an individual piece of type — a single physical block bearing one character. The term survives in the expression "out of sorts," meaning that the compositor has run out of a particular character. By extension, sort is used in digital typography to refer to any individual glyph or character within a font. A font's character set is its complete inventory of sorts. The term highlights the discrete, countable nature of the typographic alphabet — each letter, numeral, punctuation mark, and special character is a distinct sort.
