Editing Genitive case (section)

===Possessives===
To indicate possession the ending of the noun indicating the possessor changes depending on the word's ending in the [[nominative case]]. 
For example, to ''a, u, i'', or ''y'' in [[Polish language|Polish]], ''а, я, ы'', or ''и'' in [[Russian language|Russian]], ''а, я, y, ю, і, и'' or ''ей'' in [[Ukrainian language|Ukrainian]], and similar cases in other Slavic languages.

:Nominative: (pol.) "Oto Anton" / (rus.) "Вот Антон" / (ukr.) "Ось Антон" ("Here is Anton").
:Genitive: (pol.) "Oto obiad Anton'''а'''" / (rus.) "Вот обед Антон'''а'''" / (ukr.) "Ось oбід Антон'''а'''" ("Here is Anton's lunch").

Possessives can also be formed by the construction (pol.) "u [subject] jest [object]" / (rus.) "У [subject] есть [object]"/ (ukr.) "у(в) [subject] є [object]"

:Nominative: (pol.) "Oto Anton" / (rus.) "Вот Антон" / (ukr.) "Ось Антон" ("Here is Anton").
:Genitive: (pol.) "u Anton'''а''' jest obiad / (rus.) "У Антон'''а''' есть обед" / (ukr.) "У(В) Антон'''а''' є обід" ("Anton has a lunch", literally: "(There) is a lunch at Anton's").

In sentences where the possessor includes an associated pronoun, the pronoun also changes:

:Nominative: (pol.) Oto mój brat / (rus.) "Вот мой брат"/ (ukr.) "От мій брат"  ("Here is my brother").
:Genitive: (pol.) "u moj'''ego''' brat'''а''' jest obiad / (rus.) "У мо'''его''' брат'''а''' есть обед" / (ukr.) "У мо'''го''' брат'''а''' є обід"  ("My brother has a lunch", literally: "(There) is a lunch at my_brother's").

And in sentences denoting negative possession, the ending of the object noun also changes:

:Nominative: (pol.) "Oto Irena/Kornelia" / (rus.) "Вот Ирена/Корнелия" / (ukr.) "От Ірена/Корнелія"  ("Here is Irene/Kornelia").
:Genitive: (pol.) "Irena/Kornelia nie ma obiad'''u''' ("Irene/Kornelia does not have a lunch") or (pol.) "u Iren'''y'''/Korneli'''i''' nie ma obiad'''u''' ("(There) is no lunch at Irene's/Kornelia's") 
The Polish phrase "nie ma [object]" can work both as a negation of having [object] or a negation of an existence of [object], 
but the meaning of the two sentences and its structure is different. (In the first case [subject] is Irene, and in the second case [subject] is virtual, it is "the space" at Irene's place, not Irene herself)
:Genitive: (rus.) "У Ирен'''ы'''/Корнели'''и''' нет обед'''а'''" ("Irene/Kornelia does not have a lunch", literally: "(There) is no lunch at Irene's/Kornelia's"). 
The Russian word "нет" is a contraction of "не" + "есть". 
In Russian there is no distinction between [subject] not having an [object] and [object] not being present at [subject]'s.<!-- WRONG. "Ирина не имеет обеда" can be used as well -->
:Genitive: (ukr.) "Ірена/Корнелія не має обід'''у''' ("Irene does not have a lunch") or (ukr.) "y Ірен'''и'''/Корнелі'''ї''' нема(є) обід'''у''' ("At Irene's does not have a lunch") 
Note the difference  between the  spelling "не має [object]" and "нема(є) [object]" in both cases.
