In a Unix system, su stands for "substitute user" or "switch user," allowing a user to switch to another user account within the terminal. By default, running su without any arguments switches to the root user. The command su - (or su -l) not only switches to the target user but also simulates a full login, loading the user's environment variables and settings, which can be important for access to specific configurations or permissions.
