carburettor [carburettor 词源字典]: carburettor: [19] Carburettor is a derivative of carburet, an obsolete term for what is now known as carbide ‘a carbon compound’. It was originally used for a device for adding carbon to a gas for enhancing its power of illumination; the current application to a device for producing air/fuel vapour in an engine dates from the 1890s. Carburet itself was a later form of carbure, borrowed in the 1790s from French; its ultimate origin was in Latin carbō, source of English carbon.

enhance (v.): late 13c., anhaunsen "to raise, make higher," from Anglo-French enhauncer, probably from Old French enhaucier "make greater, make higher or louder; fatten, foster; raise in esteem," from Vulgar Latin *inaltiare, from Late Latin inaltare "raise, exalt," from altare "make high," from altus "high" (see old). Meaning "raise in station, wealth, or fame" attested in English from c. 1300. Related: Enhanced; enhancing.

The -h- in Old French supposedly is from influence of Frankish *hoh "high." The -n- perhaps is due to association with Provençal enansar, enanzar "promote, further," from enant "before, rather," from Latin in + ante "before."
psychedelic (adj.): occasionally psychodelic, 1956, of drugs, suggested by British-born Canadian psychiatrist Humphry Osmond (1917-2004) in a letter to Aldous Huxley and used by Osmond in a scientific paper published the next year; from Greek psykhe- "mind" (see psyche) + deloun "make visible, reveal," from delos "visible, clear," from PIE root *dyeu- "to shine" (see diurnal). In popular use from 1965 with reference to anything producing effects similar to that of a psychedelic drug or enhancing the effects of such a drug. As a noun from 1956.
