Epistemic

/ˌɛpɪˈstiːmɪk/adjective

Relating to knowledge or to how well a belief is justified.

The Greek roots

ἐπιστήμη
epistḗmē
knowledge, understanding

Literally: having to do with knowledge

The story of the word

ἐπιστήμη is knowledge that stands up, from ἐπίσταμαι, to stand over a thing and so understand it, and Plato sets it against δόξα, mere opinion. The adjective stayed rare in English until modal logic needed it: G. H. von Wright's 1951 scheme sorted modal operators into alethic, deontic and epistemic, and Jaakko Hintikka's Knowledge and Belief of 1962 turned epistemic logic into a field. Philosophers now attach it to anything that can be well or badly grounded.
