What does the prefix "sub" imply about location or position?

The prefix "sub" comes from Latin, meaning "under" or "below." This indicates a position that is beneath something else. In various contexts, such as in the terms "submarine" (underwater) or "subpar" (below standard), the prefix clearly conveys a sense of being lower in position or status. Therefore, when this prefix is present, it typically indicates that something is situated beneath or at a lower level compared to another entity. Understanding this definition is crucial, as it provides a basis for interpreting various terminologies across different fields, including science, geography, and everyday language.
