A categorical syllogism is a deductive argument that consists of two premises and a conclusion. The premises and conclusion are declarative statements that are constructed using three simple terms. Each term appears twice, as a subject and as a predicate. 

Categorical syllogisms are also referred to as categorical arguments. They are used to ascertain the category of an object or concept. 

Here's an example of a categorical syllogism:
All soldiers are patriots
No traitors are patriots
Therefore, no traitors are soldiers 

Some other examples of categorical propositions include:
"All" in "All throwers throw something"
"No" in "No fish can fly"
"Virtually all" in "Virtually all sparrows can fly"
