What does it mean to be omniscient?

To be omniscient means to have complete and unlimited knowledge. This term stems from the Latin words "omnis," meaning all, and "scientia," meaning knowledge. An omniscient entity, often referenced in literature and philosophy, is typically understood to know everything that can be known, including all thoughts, actions, and past, present, and future events. This definition aligns with concepts found in various contexts, such as religious texts describing a deity that possesses infinite wisdom. The other choices indicate varying degrees of knowledge or lack thereof, which do not align with the definition of omniscience.
