This study is set to explore the theory of speech acts with special reference to Zulu. This is done with the motive of discovering the applicability of this theory to the utterances that are issued by the speakers of this language. Particular attention is given to the performatives as a special kind of speech act. Their examination reveals that in Zulu, there are acts, which could be performed by saying something. We distinguish between explicit and inexplicit performatives. Explicit performatives contain a verb in their main clause which names the act that is performed when a performative is issued. The inexplicit performative on the other hand does not contain this verb. Acts that are restrained as far as the explicit performative is concerned, would rather be expressed by means of the inexplicit performative. Utterances such as those that express commands, customarily make use of the imperative, which is an inexplicit performative. A closer examination of how performatives are realised in Zulu, reveals that in order for the performatives to be understood as intended by the speaker, the illocutionary force, of what the speaker intends or means by the issuance of the utterance in question, comes to the surface. It is the illocutionary force which connote that an utterance is a request, a command, a warning, etc. Performatives can also be double-natured in function. One performative could be a request which is intended as an order. In this case it is the responsibility of the addressee to use contextual information in order to determine that which is the speaker's intention. In this investigation, what has surfaced as well, is that one speech act could be expressed in various different ways. For instance, a request, could be expressed by the use of a performative, an imperative, a question and a statement. Another factor which we came across in this study, and which has a significant bearing on the performative, is that they should comply with the conditions of felicity, if they are to be successful and understood as intended by the addressee. / African Languages / M.A. (African Languages)
