Seeds and cores can be found in plums, apples, lemons and oranges, cherries and other fruits. They are already fertilized, and in the kitchen they are usually thrown away or turned into oil (for example, the famous pumpkin seed oil), and in the garden they are buried in the earth in the hope that new trees will grow. Which is not always successful. Just as the so-called “brand core” (or essence) of an object or the most important requirement of a subject’s ability always fails to hit the actual core.
The even more direct approach to this word hits directly into the heart (“core” comes from Latin “cor”, i.e. the heart)): “core competency”, And so the core competence is a heartily approach – right up to the stroke.
