Vowels
The close vowels (/i/, /u/) are only present, when a semivowel ([j], [w]) is syllabic; or when a palatovelar (/kʲ/, /gʲ/, /ɣʲ/) or a labiovelar (/kʷ/, /gʷ/, /gʷʰ/) consonant precedes another consonant (see 2nd/3rd sound change).

Nominal inflection
Seven cases and all numbers remained. The ablative is lost. Singular and plural share the same suffixes, the only difference is the ablaut. The dual got an additional ablaut-grade -a-. There are seven case suffies and three numbers, resulting in 14 nominal forms.

Verbal inflection
The PIE moods subjunctive and optative are lost. The future tense has the ablaut-grade -a- which didn't exist in PIE. There are eleven verbal suffixes and three tense-ablauts, resulting in 33 verbal forms.
