Why is it “iksāt”?
Iksan : seu Iksā : você é Issa : é / he Iksi : somos Iksāt : vocês são Issi : são
Iksā is like "you are" for one guy, and iksāt is like "you guys are" for multiple people.
Because it is in second person plural :) In english we can use "you are" both for singular and for plural. But in high valyrian it is two different words :)
