|Word: a structure separated by spaces from other words within a language. In general, words are formed by one or more characters which are attached to one another. Whole words can in turn be interpreted as signs. In human languages, the elements of the words are letters; in computer languages, other symbols are used within words. See also concepts, expressions, terms, language, characters, symbols, subsentential, meaning.|
