Today when I tried to recollect all about the Azhax language, I found that I had forgotten almost everything about it.
Until now I still can’t remember why the prepositional case exists. For these prepositions there already have been the objective case, the genitive case and the ablative case (I found an archive in my laptop, in which there are all the prepositions and their corresponding cases).
Maybe… at that time I already had realized that it’s unnecessary for the prepositional case? Because in another archive, in which there are all those declensions of the nouns and the pronouns, I once annotated that the ablative case of the pronouns should be changed to the vocative case.
Oh my… I need to go back to my hometown to find that notebook out.
