What is an author's thesis?

answers1: The thesis is the main idea or reason why the author is
writing what the write. A thesis in a formal paper can often be stated
in the introduction of a paper. Sometimes though the thesis is not so
obvious and summed up in just want sentence. Your idea of the thesis
sometimes must be found after reading the author's whole piece of
writing and then concluding what their purpose or point was for
writing. That is the thesis.
