Lily flower
Lilliah is a modern elaboration of the name Lily, which refers to the flower symbolizing purity and innocence. It combines the classic botanical root with the popular '-ah' suffix, giving it a more rhythmic and lyrical quality than the shorter original. While rare, it follows the trend of expanding short nature names into more formal-sounding versions.
