popcorn

the word "popcorn" is a transparent compound formed from two english elements. the first element, "pop," is an onomatopoeic word from the late 14th century, imitating a short, explosive sound, which perfectly describes the audible action of the kernel bursting. the second element, "corn," derives from old english, a general term for the seed of a cereal plant. the compound emerged in american english in the early 19th century, named for the distinctive popping sound the dried kernels of a specific maize variety make when their internal steam pressure causes them to explode and puff up upon heating. its formation follows a straightforward descriptive logic, naming the food by its defining preparation process and its primary ingredient.
