While most of us have seen things shimmer with light and described it as sparkling, there is an equal opposite to sparkle. The word, darkle, means to become cloudy, gloomy, dark, or be concealed in the dark!
Another interesting fact about darkle is that it is a relatively new word in comparison to its antonym, sparkle! In fact, the first use of sparkle dates back to the 13th century with sparken as in ‘to spark’.
Darkle only originates in the 1800s, and while the exact origin word is unknown, it is believed that the original use of darkle was ‘darkling’.
