This noun denotes birth, specifically the moment or circumstance of nativity. In John 9:1, Jesus sees a man blind "from birth"—a condition existing since the hour of his birth. The term emphasizes the precise moment of origin, birth as a temporal marker. Classical usage phrases like "from birth" (ek genetēs) mark conditions or characteristics present from life's beginning. The translations (Spanish nacimiento, French naissance, German Geburt) all use standard birth terminology, establishing that the man's blindness was congenital, not acquired—setting up Jesus' statement that this was for God's glory, not anyone's sin.
