'euphoric' originates from New Latin, specifically the word 'euphoricus,' where the Greek prefix 'eu-' meant 'well' or 'good' and the root from Greek 'pherein' (via 'phoros') meant 'to bear' or 'to carry'.

'euphoric' developed from the noun 'euphoria' (New Latin 'euphoria'), which came from Greek 'euphoría'/'euphoros'; the adjective form in English was formed from these classical/Latin roots to produce modern 'euphoric'.

Initially connected to the idea of 'bearing well' or 'being healthy/well' in Greek, the sense shifted over time to the modern meaning of 'experiencing intense well-being or happiness'.
