A term is a word, or a combination of words, which by itself is capable of being used as a subject or predicate of a proposition. Key Points Extension, in logic, correlative words that indicate the reference of a term or concept: “extension” indicates its range of applicability by naming the particular objects that it denotes. The denotation, or extension, of a term, is the list of a class of objects referred to by the word (think of it as “how far does this word extend?”). Thus the word “planet” denotes specific objects such as Venus, Earth, Jupiter, and Neptune. Hence the collection of all the objects to which a term may correctly be applied is called the extension of that term and denotation of that term. Thus (C) and (D) only are the correct option. Additional Information Intention means the sum of the qualities which describe a general name. The scope of application of the term is to all the members of the class, and this signifies extension. The qualities or properties of content or subject matter of the term signify intention. connotation is roughly synonymous with intension. Connotation is often contrasted with denotation, which is more or less synonymous with extension. Alternatively, the connotation of the word may be thought of as the set of all its possible referents (as opposed to merely the actual ones).
