"Ŝi loĝas kun sia familio."

Translation: She lives with her family.

[JohannesP3us]

why isn't her = Ŝia?

[johmue]

That would mean that that she is living with the family of some other woman.

"sia" refers to the subject
"lia"/"ŝia"/"ilia" refers to some other person(s) in the context but not to the subject.

"Petro vizitas Brunon kun sia koramikino." (Peter is visiting Bruno with his (Peter's) girlfriend)
"Petro vizitas Brunon kun lia koramikino." (Peter is visiting Bruno with his (Bruno's) girlfriend)

Dankon! "Sia" was derived from the Latin/Spanish "se" reflexive pronoun, right?

[22decembre]

sia is the same as "sin/sit/sine" in danish :D youhou...

[ElectricCoffee]

I just realised this, too! :D

Do vi povus diri, "Tiu cxe estas Sofia. Sxi logxas kun sia familio. Tiu estas Ana. Sxi ankaux logxas kun sxia familio"? Oni scius ke mi signifas ke ambaux knabinoj logxas kun la sama familio?

[HWF10]

Jes. Sed se vi ankaŭ uzus "sia" en la dua frazo, vi signifus ke Sofia loĝas kun la familio de Sofia kaj Ana loĝas kun la familio de Ana.

Do you have to accusative case names?

[Komano.]

Would "Ŝi loĝas kun ŝia familio"(only that phrase) be correct?

[RichMusic]

No, that would imply she lives with the family of someone else (sia = her own family).

[Lochlannn]

Whats the masculine equivalent then?

[deactivated user]

There isn't one. Sia is simply a reflexive pronoun. It works with all genders.

[maja.vargo]

So, for Slovak sia means "svoj" and for Czech "svůj".
