Determination is an inner drive that motivates one to do something. In linguistics, this concept refers to the fulfillment of the prolocutor will when delivering the speech. In other words, the speech is delivered consciously and it is not out of sleepiness, drunkenness, insanity and alike. It may appear that rhetoricians’ use of rhetorical devices is unintentional. The present study seeks to explore the concept of determination in rhetorical devices, by employing a pragmatic approach and descriptive-analytic methodology. Therefore, the speech of well-known rhetoricians was studied and rhetorical devices were analyzed in terms of determination and will. The analysis included the production and reception stage. Upon analysis of six rhetorical devices, it became evident that determination played a role in the use of these devices to the extent that overlooking determination might hinder our understanding of these devices. In conclusion, the use of rhetorical devices in rhetoricians’ speech is by no mean unintentional and the concept of “intent” in their speech is not equal to determination, rather a kind of pretension.
