Likely a modern elaboration of Lana or Lani
Lanija is a contemporary name with roots that are difficult to pin down definitively. It is most likely a modern American creation, blending the popular prefix 'La-' with the name 'Nija' or an elaboration of Lana (meaning 'calm as still waters' or 'rock') or the Hawaiian Lani (meaning 'sky' or 'heaven'). Its usage is rare, appealing to parents seeking a unique, rhythmic sound.
