epistemic (English)
Where does "epistemic" come from?
The English word 'epistemic' traces its roots back to Proto-Indo-European elements, combining '*h₁epi' meaning 'on'[5] with the root '*steh₂-' meaning 'to stand (up)'[1][3]. These elements formed the Ancient Greek verb 'ἐπίσταμαι' meaning 'to have knowledge of, know', which yielded the noun 'ἐπιστήμη' meaning 'knowledge' or 'science'[1]. By adding the English adjective suffix '-ic', the term developed into 'epistemic', relating to knowledge, cognition, or epistemology[1].
