To base is to create or define an element by relating it to a specific element.
A base is an element which another element has been created from or defined by.
Basic, or primary, is a trait which indicates that an element provides a required input for a specific system.
Describing an element as basic to another form does not necessarily indicate any perception of the relative complexity of the relevant elements. For example, a regular monetary income may be fundamental to Jane's health within a specific formal context; however, creating and sustaining that income may seem anywhere from quite simple to incomprehensively complex in different instances of that type of goal.
