When we talk about a typical case, we refer to something that is ordinary or standard. However, there are a number of different synonyms that can be used to describe this concept. For example, you could use the term "common case" to refer to something that is frequently seen or encountered. Alternatively, you could use the phrase "usual scenario" to describe a predictable situation that arises regularly. Other synonyms for typical case might include "standard example," "regular instance," or "typical example." Whatever word or phrase you choose to use, the goal is to convey the idea of something that is typical or representative of a larger group or category.
