ABSTRACT
A type-sentence or sentence-design is just a string of words conforming to the grammatical rules of a natural language. A sentence-token or event* (or utterance or inscription) is a particular occurrence of that language pattern which can be put to varied uses. A sentence-token, whether inscription or utterance, is a concrete object that can be examined and anatomized. It has parts and relations between the parts. It has semantic rules relating the parts to their meanings and syntactic rules governing the ways in which these parts can be put together. Even to be a genuine empirical sentence, in the grammatical sense, a sentence must have such a content. If a sentence uttered misdescribes the situation to which it is affixed by the context of utterance, it cannot be true. But the descriptive content of a sentence is prior to its use.
