Comitative case may be confused with Instrumental case, as both of them may be translated with English preposition “with”. The difference is that either word “together” or presence of companion or emotion is implied in Comitative case, while Instrumental case means “with use of”, “using”. Compare: “He speaks with fear in his voice” = “Tagashn ufursha mogtabishi” (COM) vs. “He speaks with flattery” = “Tagashn glizgirzi” (INS), “He talks with elves” = “Tashugb golugsha” (COM) vs. “He talks with his mouth” = “Tashugb pugtabirzi” (INS), “Kill the orc with knife”1) = “Dog urukum kirmsha” (COM) vs. “Kill the orc with (use of) knife”2) = “Dog urukum kirmirzi” (INS).
The verb “gûk-” (to fill) requires indirect object (if present) to be in Instrumental case: “Fill the barrels with fish” = “Gûk kralt skabirzi”. But “kralt skabsha” means that fish is already in the barrels.
