"Sȳro anno āeksio kirine issa."

Translation: The good horse's master is glad.

[TheDuoWizard]

How do you know if it's "the good horse's master" or "the master's good horse"?

[Palastram]

aaeksio ends in o anyway, but horse ends in -e in the nominative. Because horse ends in o it is in the genitive.

[MadLatinist]

"The master's good horse" would be Sȳz anne āeksiō (or, more likely, Āeksiō sȳz anne).

[FerBound]

Why is the master taking the genitive case if the owner in this sentence is the horse??

[MadLatinist]

Āeksio just happens to end in -o in the nominative (the genitive is actually āeksiō with a long o.) See previous comments for further discussion.

[Galactus39]

It doesn't matter if it is good or glad

[DanielDE-VA]

wouldn't this be the master's good horse is glad? Does it mean the same?
