köken: From pre-Middle Korean *kwùmùk, the modern form preserving the velar nature of the final consonant. First appeared in the seventeenth century as a distinctively Modern Korean form, displacing the Middle Korean form 구무 (Yale: kwùmwù), which still survives in some dialects.
köken: Borrowed from Classical Persian چشمه (čašma, “spring, source; spectacles”), related to چشم (čašm, “eye”), itself ultimately from Proto-Indo-Iranian *čáćšma (“sight”). Related to Sanskrit चक्षु (cakṣu). Other borrowings from Persian are Assamese চছমা (sosoma), Bengali চশমা (cośma), Punjabi ਚਸ਼ਮਾ (caśmā), Gujarati ચશ્માં (caśmā̃), Marathi चष्मा (caṣmā).

köken: From Proto-Finnic *aukko (compare Estonian auk, Votic aukko), either derived from the same root as avata, aukea, or alternatively proposed to be a borrowing from Proto-Germanic *augô (“eye”).
degree, grade, level (step or stage in any scale of values) · degree, extent (amount that an entity possesses a certain property) · step, rung (one of a set of rests in a stair or ladder)
From Early Medieval Latin traugus, a "barbarous" Latin word first attested in the Ripuarian Law, probably related to torus (“round hill”). Thought to be of Celtic, specifically Gaulish, origin. However, others have suggested a borrowing from Ancient Greek τρῦπα (trûpa, “hole”), instead. Related to Catalan and Occitan trauc.
