Did you know?

Is it pixelated or pixilated?

Pixelated is used to describe digital images in which individual pixels are discernable, as when you look closely at a large photo and can see the tiny dots that make up the image. Pixilated (coined from pixie, a pixie being a cheerful, mischievous sprite) is usually used to describe things considered whimsical, or people who seem dazed or lost in thought. While pixelated is a late 20th century coinage, pixilated has been in use since the mid-19th century.
