"These ones are the good long swords."

Translation: Kesi sȳri korzi issi.

[CarisaMaxine]

Why isn't "Bisi syri korzi issi" correct? Aren't bisi and kesi the same meaning?

[xPsGoDWh]

No, the distinction just isn't made in English. "Bisi" is for animated beings, while "kesi" is for inanimate things.
