In Russian, the dative case is important because it shows us who's getting something or benefiting from an action. It helps us understand who or what actions are being done for. Some small words called prepositions need to be used with nouns in the dative case. Learning these prepositions and how to change noun endings is really helpful for understanding Russian grammar.

Prepositions That Use the Dative Case:

1. к (to, towards)

   • This shows you're going toward a person or place.
   • Example: Я иду к другу. (I am going to my friend.)

2. по (by, along, according to)

   • This is used when you're moving along something or following an idea.
   • Example: Мы идём по улице. (We are walking along the street.)

3. для (for)

   • This word tells us the purpose of something. It usually means something is meant to help someone.
   • Example: Это подарок для тебя. (This is a gift for you.)

4. с (with)

   • You can use this word when talking about being with someone.
   • Example: Я пришёл с другом. (I came with a friend.)

How Noun Endings Change in the Dative Case:

Nouns change their endings based on whether they are masculine, feminine, neuter, and if they are singular or plural.

• Masculine Nouns:
  Typically, you add -у or -ю.

  • Example: Друг (friend) becomes другу.

• Feminine Nouns:
  Usually, you add -е or -ии (if it ends in -а, just add -е).

  • Example: Кошка (cat) becomes кошке.

• Neuter Nouns:
  Generally, you add -у or -ю.

  • Example: Окно (window) becomes окну.

• Plural Nouns:
  For most plural nouns, you add -ам or -ям.

  • Example: Друзья (friends) becomes друзьям.

Example Sentences:

1. Я пишу письмо другу. (I am writing a letter to a friend.)
2. Этот цветок для мамы. (This flower is for mom.)
3. Мы встречаемся с друзьями в парке. (We are meeting with friends in the park.)
