There have been many arguments about pronouns under the assumption that a pronoun is a word used instead of a noun/noun phrase and a pronoun and its antecedent are co-referential. A pronoun is categorized one of anaphors when it is understood as being co-referential with a referring expression occurring elsewhere in the sentence, In addition, this paper observes, a pronoun also directly indicates an object like a noun/noun phrase. Most pronouns have indexicality and deictic function. They are pragmatically controlled in that referring objects change according to the context in which they occur, and that the referents can`t be determined without regarding the context. For effective and successful communication reflecting their psychological attitudes, speakers select pronouns appropriate to the context. To convey intended pragmatic meanings, speakers sometimes decide to repeat the same nouns/noun phrases instead of using pronouns. Pronouns are linguistic and pragmatic entities. They couldn`t be defined by linguistic meanings or structures alone. They should be analyzed pragmatically. The correct interpretation and the appropriate use of pronouns need not only their linguistic phenomena but also non-linguistic contexts including speakers/hearers and our knowledge about the physical and social world.
