Did You Know?
If you have ever extracted a winkle from its shell, then you understand how the verb "winkle" came to be. The word "winkle" is short for "periwinkle," the name of a marine or freshwater snail. "Periwinkle" is ultimately derived from Latin "pina," the name of a mussel, and Old English "wincle," a snail shell. Evidently the personnel of World War I's Allied Powers found their duty of finding and removing the enemy from the trenches analogous to extracting a well-entrenched snail and began using "winkle" to describe their efforts. The action of "winkling the enemy out" was later extended to other situations, such as "winkling information out of someone."
