An insinuation creates inductive form for the speech, a movement from specifics to general. It is particulary well suited for a hostile or bored audience, one that may tune out if a thesis sentence is posited at the outset. An introduction sets up a deductive form for the speech, from general statement of thesis and claims to specific support for the thesis and claims. Two crucial elements of an introduction are a clearly stated thesis sentence and a preview of main points to be addressed in the body of the work, in this case a speech. Opening Purpose Gain attention, or establish oratorical time and space.
Speaker sparks audience attention with a decisive start.
A speech is an instance of embodied communication, constrained by presence and time. To create oratorical time and space is to create this specific time and this specific place as one where people come together to participate in a collective enterprise, an audience. Methods Rhetorical question. A common way of opening a speech, and often poorly used. The effective rhetorical question is one to which the speaker expects a specific answer.
