Why is it vali not vala? Is it because its plural?
Yes.. the "i" is the inclination for plurals
Thank you, I realized it after a few trials
What is the difference between Kirini vali iksi and Vali kirini issi. Is that just the order of words because of iksi and issi?
There is no difference. It's just preference. But later on it starts to matter when you have different cases and it makes sense having it in a logical order. I think "Kirini vali" makes more sense than "Vali kirini".
