In a sincere, honest, and authentic way; truly and without pretending.
From 'genuine' (from Latin 'genuinus' meaning 'natural' or 'innate,' possibly related to 'genus' for kind/type). The suffix '-ly' converts the adjective to an adverb. The root may connect to 'genu' (knee), as newborns were placed on their father's knee to claim paternity in Roman custom.
Some scholars think 'genuine' comes from the Roman practice where a father would place a newborn on his knee to legitimize it—if he did this, the child was 'genuine' or truly his. It's a wild theory connecting an intimate family ritual to our word for authenticity!
