The information and facts that support a claim are referred to as the grounds of an argument. The other three components of a Toulmin argument—backing, qualifier, and rebuttal—are not required but may be added as needed. Using these aspects correctly can assist authors in developing complete, complex arguments. The grounds for writing usually include some combination of evidence, logic, and experience. For example, an author might argue for including health benefits on the grounds that scientific studies have shown that exercise is good for you, even though there is no actual medical reason to do so. The writer would also need to include a qualification (i.e., "but only under certain conditions") if this argument were used in a court of law. Finally, the writer could use it as a rebuttal to someone who was arguing against including health benefits by saying, "even though nobody has ever been killed by exercise, we should still include health benefits because science shows it is helpful." With all of these elements included, the writer has developed a complete argument for including health benefits. In general, grounds for writing are any facts or examples used to support a point while explaining why that point should be accepted by readers. They can be anything that helps explain your argument or comment on it.
