Introduction to old coskian

Old coskian is the precursor to coskian, now, realistically, old coskian should not sound as similar as it does to modern coskian, but if anything, my goal with old coskian is making a more german-old english-y vibe, so having declensions, verb conjugations and more gender agreement.

All the grammar explanations will assume you know the correspondent matter in modern coskian at least to some extent, but this does not necessarily forbid intelligibility.
