本文的主旨是探討華語稱謂詞和人稱代詞的活用。稱謂詞具有可以頂替人稱代詞的言外功能，指稱交談事件中的說話者或對方。人稱代詞也可以延伸出泛指的用法，兼具本用和活用的特徵。稱謂詞作為面稱或自稱可以反映交談者間的權利宰制關係或促進彼此的親和力。有些稱謂詞充當情感用語，指稱自我，表現出高亢的情緒。本文也觸及代詞的情感用法和約束理論的關係。

The paper explores the imposter function of terms of address and pronouns in Mandarin. Terms of address can assume the exophoric function of pronoun and refer to speaker or addressee in a speech event. Personal pronouns can take up the generic function featuring both its primary and extended function. When denoting speaker or addressee, they can express the power relationship between interlocutors with respect to a difference in social status as well as the degree of intimacy and even enhance solidarity in speech community. Some terms of address can be epithets referring to the speaker himself or herself in a high state of emotion. The paper also brings the emotive function of pronouns to bear on the issue of the principle of binding.
