Proto-Riphic

Proto-Riphic is a descendant of Late PIE with a Proto-Germanic and Proto-Balto-Slavic hybrid aesthetic.

Phonology

Proto-Riphic is a satem language, which means that the original PIE palatovelars are fronted to alveolar. It also underwent a sound shift similar to Grimm's law:

• PIE voiceless stops -> voiceless fricatives
• PIE "plain voiced"/glottalic stops -> voiceless stops
• PIE "voiced aspirates" -> voiced stops

Unlike in Proto-Germanic, though, there is no Verner's law in Proto-Nithish.

Vowels

A hybrid of Proto-Slavic and Thedish?

Morphology

Proto-Riphic retained all 8 cases of PIE, as well as singular, dual, and plural forms of nouns. Its verbal morphology, though, is much simpler. It's notable for having an evidentiality distinction in verbs from the original PIE sigmatic aorist.
