A claim is a type of argumentative thesis – we usually call it a claim when it is being used in a persuasive essay. Claims need to be defended by you with logical, persuasive reasoning. Claims can also be challenged.
The most common types of claims are
- claims of policy (we must do something!),
- claims of value (this is good! or this is bad!),
- claims of definition (this is what it is)
- claims of cause/effect (X has caused Y or X will cause Y)
