What word goes for having unlimited knowledge?

There isn't one single perfect word for having unlimited knowledge, as the concept itself is often considered impossible or even paradoxical.

Here are some options depending on the specific context:

Formal/Philosophical:

* Omniscient: This is the most common word, meaning "having infinite knowledge or awareness". It's often used in religious contexts to describe deities.

* All-knowing: This is a more informal version of "omniscient".

* Panoramic: This suggests a wide, all-encompassing view of knowledge, but it's not as strong as "omniscient".

Informal/Figurative:

* Know-it-all: This word carries a negative connotation, suggesting someone who is arrogant about their knowledge, even if it's not actually unlimited.

* Encyclopedic: This describes someone with vast knowledge, but not necessarily unlimited.

* Sage: This refers to a wise person with deep knowledge, but doesn't necessarily imply unlimited knowledge.

Ultimately, the best word depends on the specific context and the nuance you want to convey.
