How to use kernel
Kernel is used literally for the edible center of nuts and seeds, and figuratively for the essential or most important part of an idea, argument, or problem. In computing, it refers to the core of an operating system. The figurative sense often appears in the phrase 'kernel of truth' to suggest something valuable at the heart of a larger statement.
Common phrases

A common mistake
Learners sometimes confuse kernel with kernel the computing term and assume all uses are technical; actually, the noun sense meaning 'core or heart' is common in everyday, non-technical English.
