In Russian, there are two words, "для" and "к." These words help us talk about purpose, but they are used in different ways. Knowing when to use each one can make your speaking skills better.

Understanding "для"

1. Purpose:
   The word "для" means "for" in English. We use it to show what something is meant for. It usually goes before a noun in a special form called the Genitive case.

2. Examples:

   • Я купил подарок для тебя. (I bought a gift for you.)
   • Это книга для детей. (This is a book for children.)

3. Usage:
   When you use "для," it means something is meant for a person or group. For example:

   • Он готовит еду для гостей. (He is cooking food for the guests.)

Understanding "к"

1. Purpose:
   The word "к" means "to" or "toward" in English. We use it to talk about actions moving toward a person or place. It comes before a noun in a different form called the Dative case.

2. Examples:

   • Я пошёл к врачу. (I went to the doctor.)
   • Она пришла к нам. (She came to us.)

3. Usage:
   When you use "к," it means moving toward something, like going to see someone or reaching a goal. For example:

   • Я читаю книгу к экзамену. (I am reading a book for the exam.)
