Editing Comitative case (section)

===Indo-European languages===
====Latvian====
In Latvian, both instrumental and comitative are expressed with the preposition {{lang|lv|ar}}<ref name=Stolz2006 />{{rp|102}} However, it is used only when the companion is in accusative and singular or when it is in dative and plural. Otherwise the co-ordinating conjunction {{lang|lv|un}} is used.<ref name=Stolz2006 />{{rp|21}}

{{interlinear|indent=3|lang=lv
|un Nelda ar Rudolfu ļoti nozīmīgi pa-skatījās uz Ernestīni
|and Nelda.NOM COM Rudolf.ACC very significantly at-look.PRET.REFL.3 on Ernestine.ACC
|'And Nelda and Rudolf looked very knowingly at Ernestine.'<ref name=Stolz2006 />{{rp|21}}}}

In the example above, {{lang|lv|ar}} is used because Rudolf, the companion, is in accusative and singular. Below, it is used in the other case that it is allowed, with a dative plural companion.
