Genius refers to someone possessing extraordinary intelligence or skill; especially somebody who has demonstrated this by a creative or original work in science, music, art etc. It commonly describes extraordinary mental capacity, inspiration, a mental leap, an extraordinary creative process, and the tutelary deity or spirit of a place or person, which gives the term a broader and more practical sense than a single short definition would suggest. Depending on context, it can also point to ingenious, brilliant, very clever, or original, so the category can cover literal uses, related ideas, and more figurative extensions of the same core meaning. Taken together, these meanings present Genius as a flexible theme rather than a narrowly technical label, covering the central idea people usually mean when they use the word while still leaving room for closely related senses that appear in real language. Genius therefore works well as a quotation category because it can hold direct statements about the subject, figurative uses that borrow its meaning, and broader reflections that stay anchored to the same central idea. Genius is not limited to a single rigid definition in ordinary language, and that wider range is part of what makes the category useful for grouping related material without losing the term's main sense.
