Lily; flower
Liliahna is a modern, elaborate elaboration of the name Lily or Lilian. It combines the floral imagery of the lily flower with the popular '-ana' suffix, resulting in a rhythmic, multi-syllabic choice. While it shares roots with the Latin 'lilium', this specific spelling is a contemporary American creation.
