"Kesy blēno naejon issa?"

Translation: Is this the front side of the mountain?

[fp8LO0pf]

Shouldn't it be 'Keson blēno naejon issa' as 'naejon' is terrestrial?

[Likhithmaadhav]

'Kesy' is the substantive form used when not followed by any particular noun.
'Keson naejon' where naejon is in the nominative form is a correct expression. 'Keson bleeno naejon' where naejon is in the accusative form is not.

[StephieRice]

Naejon is not in the accusative. Issa does not make anything take the accusative

I have a pronunciation question. I tend to pronounce the "y" at the end of a word more like an "i" as in "kesi". For example in the word "azantyssy" I pronounce the first y like "ü" and the second one more like an "i". Is that correct or should both have the "ü" sound? Because in this audio file here I hear the "ü" in kesy a bit more than ususal.
