What is the Greek word for class?

There isn't one single perfect Greek word for "class" because the meaning depends on the context. Here are a few possibilities, depending on what kind of "class" you mean:

* τάξη (taxi): This is the most common translation and refers to a school class, a grade level, or a category/division of things.

* κλάση (klasi): This is a loanword from French ("classe") and is often used in scientific contexts (e.g., a class of animals) or social contexts (e.g., the upper class).

* ομάδα (omaða): This means "group" and could be used to refer to a class of people or things, especially if it's a more informal group.

* κατηγορία (kategoriā): This translates to "category" and can be appropriate depending on the context.

Therefore, the best translation of "class" in Greek depends entirely on its intended meaning.
