From Quine's "Two Dogmas of Empiricism" —

"Meaning, let us remember, is not to be identified with naming. Frege's example of 'Evening Star' and 'Morning Star' and Russell's of 'Scott' and 'the author of Waverly ', illustrate that terms can name the same thing but differ in meaning. The distinction between meaning and naming is no less important at the level of abstract terms. The terms '9' and 'the number of the planets' name one and the same abstract entity but presumably must be regarded as unlike in meaning; for astronomical observation was needed, and not mere reflection on meanings, to determine the sameness of the entity in question.

The above examples consist of singular terms, concrete and abstract. With general terms, or predicates, the situation is somewhat different but parallel. Whereas a singular term purports to name an entity, abstract or concrete, a general term does not; but a general term is true  of an entity, or of each of many, or of none."
