In Russian, the word "к" is used to talk about direction or purpose. It always works with a special form of nouns called the dative case. Let’s make it simple:

Showing Direction:

• How to Use It: You use "к" when you are moving towards a person or a place.
• Example:
  • Я иду к другу.
    (This means “I am going to my friend.”)

Showing Purpose:

• How to Use It: You can use "к" to say what your goal or intention is. It usually goes with nouns.
• Example:
  • Она пришла к успеху.
    (This means “She has achieved success.”)

Quick Reminder:

Just remember, "к" always goes with the dative case. It helps show movement or a goal toward someone or something.
