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.

wizard (n.)youdaoicibaDictYouDict
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.
