wizard [wizard 词源字典]: wizard: [15] A wizard is etymologically a ‘wise’ man – indeed originally the word was used for ‘philosopher’ or ‘sage’, without any suggestion of magical practices. It was derived from wise. The distinction between philosophy and magic was sufficiently blurred in the Middle Ages for the sense ‘magician’ to emerge in the 16th century, and that is the one which has prevailed.

aesthetic (n.): 1798, from German Ästhetisch or French esthétique, both from Greek aisthetikos "sensitive, perceptive," from aisthanesthai "to perceive (by the senses or by the mind), to feel," from PIE *awis-dh-yo-, from root *au- "to perceive" (see audience).

Popularized in English by translation of Immanuel Kant, and used originally in the classically correct sense "the science which treats of the conditions of sensuous perception." Kant had tried to correct the term after Alexander Baumgarten had taken it in German to mean "criticism of taste" (1750s), but Baumgarten's sense attained popularity in English c. 1830s (despite scholarly resistance) and removed the word from any philosophical base. Walter Pater used it (1868) to describe the late 19c. movement that advocated "art for art's sake," which further blurred the sense. As an adjective by 1803. Related: Aesthetically.
blear (adj.): c. 1300, blere "watery, rheumy," perhaps related to blur. Compare Middle High German blerre "having blurred vision."
blur (v.): 1580s, and thus probably from blur (n.), but the dates are close and either might be the original. Related: Blurred; blurring.
fuzzy (adj.): 1610s, "soft, spongy;" a dialectal word of uncertain origin, apparently from fuzz (n.) + -y (2), but perhaps an import from continental Germanic. Compare Low German fussig "weak, loose, spongy," Dutch voos "spongy." From 1713 as "covered with fuzz;" 1778 as "blurred;" and 1937 as "imprecise," with reference to thought, etc. Related: Fuzzily; fuzziness.
vignette (n.): 1751, "decorative design," originally a design in the form of vine tendrils around the borders of a book page, especially a picture page, from French vignette, from Old French diminutive of vigne "vineyard" (see vine). Sense transferred from the border to the picture itself, then (1853) to a type of small photographic portrait with blurred edges very popular mid-19c. Meaning "literary sketch" is first recorded 1880, probably from the photographic sense.
wizard (n.): early 15c., "philosopher, sage," from Middle English wys "wise" (see wise (adj.)) + -ard. Compare Lithuanian zynyste "magic," zynys "sorcerer," zyne "witch," all from zinoti "to know." The ground sense is perhaps "to know the future." The meaning "one with magical power, one proficient in the occult sciences" did not emerge distinctly until c. 1550, the distinction between philosophy and magic being blurred in the Middle Ages. As a slang word meaning "excellent" it is recorded from 1922.
