It’s not a direct object. This is a phrase, not a complete sentence, therefore it has no object and no verb.
Genitive is used here to express the meaning 'of': таре́лка = plate, ри́са = of rice.
This website here helped me with getting used to Genitive http://www.practicerussian.com/Lessons/Lesson3/Lesson3_DrillGrammar.aspx I wish they programmed the test a little better, but it still does its job. If you don't have a Russian keyboard option you can just mouse click the letters. Hope it helps!
Тарелка is nominative.
They look the same, but their grammatical function is different. This is because тарелка and рис belong to different declensions, and they have different ending patterns. Тарелка is nominative, тарелки is genitive (because it's a feminine, a-declension); рис is nominative, риса is genitive (because it's a masculine, o-declension; most masculine words are declined like this).
Yes, when talking about quantities, you use genitive to express the thing measured.
It doesn't. It pronounces «тарелка» (at least in the normal speed; I can't access the faster pronunciation from the comment section).
In other contexts, yes:
- Я съе́ла таре́лку ри́са. 'I ate a plate of rice.'
- Он съел две таре́лки ри́са за раз. 'He ate two plates of rice at a time.'
But when we don't have context, we usually use nominative as the default case.
so i have a question
technically, a plate of rice can either mean
a plate with rice on/in it
a plate made from rice (for example as an art project)
in my native language (Dutch) these are different expressions, for 1 we'd say 'een bord rijst', for 2 'een bord van rijst'. I was wondering whether in russian this sentence means 1, 2 or both?
Your endings are correct, but they are only used for feminine nouns:
- вода́ nominative of 'water' — воды́ genitive of 'water',
- статья́ nominative of 'article' — статьи́ genitive of 'article',
- ка́ша nominative of 'porridge' — ка́ши genitive of 'porridge',
- те́нь nominative of 'shadow' — те́ни genitive of 'shadow'.
While a small group of masculine nouns is declined as if it were feminine (па́па nom. 'Dad' — па́пы gen. 'Dad'), most masculine nouns use different set of endings, -а / -я, in genitive:
- ри́с nominative of 'rice' — ри́са genitive of 'rice',
- паро́ль nominative of 'password' — паро́ля genitive of 'password'.
The same set of endinds, -а / -я, is used for neuter nouns:
- я́блоко nominative of 'apple' — я́блока genitive of 'apple',
- со́лнце nominative of 'sun' — со́лнца genitive of 'sun',
- варе́нье nominative of 'varenye (type of jam)' — варе́нья genitive of 'varenye (type of jam)'.
Whereas in English you'd use a preposition ("of") or an apostrophe s (Jenny's) to indicate possession/relationships, Russian almost always uses genitive case - this precludes the use of a preposition generally, but requires declension of the second object. For instance, in English you might say "My mom's friend", but in Russian you'd say "Друг моей мамы". A house door ("a door of the house") would be a "Дверь дома".
