Etymology
Origin of iridescent
Explanation
Iridescent is an adjective that means lustrous and pearly, giving off a brilliant sheen like an oil slick or, well, a pearl. Iridescent came to be in 1796, when some enthusiastic word maker took the Latin word iris, which means "rainbow," and morphed it into an English word that describes anything giving off a luminous, rainbow sheen or that changes color in the light. It's a great descriptive word — if you can resist the urge to spell it with an extra "r."
