"optical instrument creating and exhibiting, by reflection, a variety of beautiful colors and symmetrical forms," 1817, literally "observer of beautiful forms," coined by its inventor, Scottish scientist David Brewster (1781-1868), from Greek kalos "beautiful, beauteous" (see Callisto) + eidos "shape" (see -oid) + -scope, on model of telescope, etc. They sold by the thousands in the few years after their invention, but Brewster failed to secure a patent.
Figurative meaning "constantly changing pattern" is first attested 1819 in Lord Byron, whose publisher had sent him one of the toys. As a verb, from 1891. A kaleidophone (1827) was invented by English inventor Charles Wheatstone (1802-1875) to make sound waves visible.
Middle English -ik, -ick, word-forming element making adjectives, "having to do with, having the nature of, being, made of, caused by, similar to," from French -ique and directly from Latin -icus or from cognate Greek -ikos "in the manner of; pertaining to." From PIE adjective suffix *-(i)ko, which also yielded Slavic -isku, adjectival suffix indicating origin, the source of the -sky (Russian -skii) in many surnames. In chemistry, indicating a higher valence than names in -ous (first in benzoic, 1791).
In Middle English and after often spelled -ick, -ike, -ique. Variant forms in -ick (critick, ethick) were common in early Modern English and survived in English dictionaries into early 19c. This spelling was supported by Johnson but opposed by Webster, who prevailed.
