core
Heart of something
The core of something is its innermost part.
The cores of some things – like apples – are dispensable.
When you core an apple, you remove its core.
The core of something abstract is usually taken to be the most important, essential part: What is the core of your argument?
In computing, a core is an element of hardware used in memory.
