Oops... In Almaqerin I used the following evolution:

    case endings --> suffixes --> postpositions --> prepositions

The switch from postpositions to prepositions is a feature
of Almaqerin, whereas the 'brother' language Sitarwelas
only shows:
    case endings --> suffixes / postpositions

(suffixes are still bound to the noun, but do not decline

I thought that "case endings" were very ancient features in
(real) languages, and that the evolution I adopted would look
quite natural. Perhaps that's not the case?
