What is the central focus of an argumentative piece called?

The central focus of an argumentative piece is referred to as the claim. A claim is the main argument or assertion that the writer puts forward to persuade the reader of a particular point of view. It serves as the foundation for the entire argument, providing direction and structure to the piece. The claim can be supported with evidence and reasoning throughout the text, and it is what the writer seeks to prove or argue for.

While theme refers to the underlying message or central idea of a work, symbolism involves the use of symbols to represent larger concepts. Tone, on the other hand, conveys the author's attitude toward the subject or audience. Each of these elements plays a role in writing, but they do not represent the core argumentative focus that defines the claim in an argumentative work.
