Etymology

The word genuine traces back to Latin genuinus ("natural, native"), derived from genu (knee). Its connection to authenticity stems from the Roman practice of acknowledging a child's legitimacy by placing them on the father's knee. Over time, genuine expanded from "legitimate by birth" to broadly signify anything authentic or sincere.
