Noun Irregularities
1. The Genitive II.There is a small group of nouns, mostly referring to food, which uses the suffix -y for the Genitive Singular. Not all nouns referring to food take this Genitive II ending, so you will have to memorize those that do.

2. The Prepositional II. The second Prepositional case is marked by an (always) accented ending -y. However, this ending is not used with all the prepositions requiring the Prepositional case but only with the prepositions на and в. It is not used with the preposition o or any other preposition governing the Prepositional case. So one would say “я видел его в саду” (I saw him in the garden) but “мы говорили о саде” (we talked about the garden).
