Thesis
Now you are ready to create a thesis for your speech. A thesis
is a

"A thesis statement generally consists of two parts: your topic, and then the analysis, explanation(s), or assertion(s) that you're making about the topic." (from the Online Writing Lab, http://owl.english.purdue.edu/handouts/general/gl_thesis.html)
