Abridged History of the 10th Age
Poetic Varan was developed as a separate language of court poetry some time during the Third or Fourth Age and, while it has changed and grown with the core of the language, the general rules that apply have stayed more or less constant, owing to it being a wholly contrived tongue removed from the organic growth of the main language.
The primary feature of Poetic (or Ballad) Varan is that it eschews the complex system of declension (which has been incorporated to deal with words from other languages or words whose root usage has fallen away) and incorporates ALL nouns into a SINGLE unique poetic declension. In some ways this is simpler, but in many others it is not – for one, many of the cases borrowed from the elvish languages are conflated and for another, many cases have indistinguishable endings. Current scholarly theory on the subject believes the purpose of this was to allow rhyming to be more prevalent (and useful) in court poetry since with the withering of case-endings vocabulary makes a stronger case for rhymes.
Of course, there are other differences as well, which will be enumerated here later.
