Varðinekvas/Old

So, yep, Old 'Nekvas that is. AKA Western dialect with less substrate.

Features

 * PIE roots left almost unchanged
 * retained most of the endings
 * generally satem changes:
 * most aspirated plosives become their fricative counterparts
 * most palatalized velar plosives become retroflex fricatives, aspirated palatalized velar plosives behave in the same way as their plain counterparts
 * some vowels and /VS/ (vowel-semivowel) sequences become diphthongs
 * most /VSV/ sequences become diphthongs
 * laryngeals become /ɒ/ in most cases; rarely their realization depends on a neighboring vowel.
 * no defined infinitive
 * fronting of vowels after fricatives developed from (unaspirated) palatalized plosives
