Etymology

The word "unnatural" combines the Germanic prefix "un-" (a staple in English for negation) with the Latin-derived "natural," creating a direct contrast to what is inherent or expected in nature. This hybrid structure reflects English's tendency to merge Germanic and Latinate elements for precise expression. The term originally emphasized physical deviation from nature (e.g., supernatural phenomena) but later expanded to describe human behavior violating societal or biological norms.
