Hyperfrench
Hyperfrench (rug Fusieznyvier, literally "Modern French") is a language of Irta's France. It is notable for being the least conservative Indo-European language in Irta, grammatically.
Timeline
Around 1300 Parisian French started evolving very rapidly, around the fifteenth century it had a similar aesthetic to our Modern French. Around the seventeenth century there was another huge series of sound shifts (including a chain shift l -> r -> h, vowel shifts and Havlik's law) as well as grammatical shifts due to the loss of prestige of Literary French in Irta. Today's Hyperfrench is a quasi-polysynthetic language with clitic complexes and bipersonal agreement, very unusual for Indo-European.
