I thought "Yes" was "Kessa", and not "Issa" . At least that's what it says everywhere on the internet.
Pretty sure the inventor of high valyrian made this course, so I would go with what it says
The course is not made by the inventor, but in an official page of high valyrian does say that yes is kessa, and that one is made by the inventor
The course is made by the inventor (I am him), and the page you're referring to is not official, and was not written by me. Kessa is used in future contexts; issa is used otherwise.
Squeeee! Fangirling a tad and giving you a lingot. Kirimvose for dropping in on the boards! So happy that there's audio now too!
"Kessa" is another form of "issa". There are a lot of forms of low valyrian through Essos and it's possible "kessa" comes from one of the 10+ dialects
I would presume that there is actually no word for Yes, as mentioned in the notes for this exercise, but the positive reply will echo the verb in the question. Issa meaning 'it is'; kessa meaning possibly 'it does, goes, has, etc...'
According to this page, both are forms of the verb 'to be', but issa is present tense, whereas kessa is future tense, so a precise translation might be "it is so" or "it will be so" respectively. So perhaps you'd use "issa" in answer to an question about how things are, but "kessa" in response to a request to do something?
Wait, what? Issa mean He/she/it, if is a firs lesson of basic right. Yes was Kessa
Issa means "he/she/it is", not just "he/she/it."
They're saying "it is [so]" as a kind of agreement. Presumably keppa means something similar, a verb.
