Etymology

The word kernel traces back to Old English cyrnel, a diminutive of corn (grain). Over time, it evolved from literally meaning "a small seed" to metaphorically representing the "core" of an idea or system. The computing sense emerged in the 1970s, likening the OS core to the essential part of a seed.
