Skillfulness → It is formed from "skill" (from Old Norse *skil*, meaning to discern or understand) and "-fulness" (meaning the state of being full of). The word "skillfulness" means the state of being full of skill or having a high level of ability in a particular area.
Think of 'skill' as the ability to understand or discern something well, and '-fulness' means being full of that ability. This helps you remember that skillfulness refers to being full of skill.
