Proto-Hesperic (2018)

Proto-Hesperic is a Macro-Indo-European diachronic conlang by Jörg Rhiemeier that is currently under construction, and represents the reconstructed common ancestor of the Hesperic language family. It is a lostlang and forms a part of the League of Lost Languages. Proto-Hesperic is an agglutinating language related to Proto-Indo-European, assumed to have been spoken in Central Europe around 4000 BC. The vocabulary is in part based on Proto-Indo-European, in part on words with uncertain etymologies in Celtic and Germanic that may be loanwords from lost substratum languages; there are also some original creations in the vocabulary and a few words from argots such as Shelta or Rotwelsch.
