Abstract: Following J. Ross, I argue that words in two sentences are used univocally if they have the same synonyms, antonyms, determinates, determinables, etc.; analogically if they have some of the same synonyms, etc; and equivocally if they have none of the same synonyms, etc. An analogical sense of a word is a standard sense that it may have in many different sentences. By contrast, a metaphorical sense of a word or token sentence is a new sense generated by the meaning of the type sentence and a new context. Metaphorical sentences have truth-values.

Keywords: analogy, equivocal, metaphor, Ross, synonymy, univocal,
