To compare adjectives in Russian, we use two main forms: comparatives and superlatives.

Comparatives:

1. How to Form:

   • You add -ее (-ee) or -ей (-ey) to the adjective.
   • Example:
     • "большой" means "big." When you change it, it becomes "больше," meaning "bigger."

2. How to Use:

   • This shows that something is more than another.
   • Sentence: "Эта книга больше той." means "This book is bigger than that one."

Superlatives:

1. How to Form:

   • You say "самый" (which means "the most") and then add the adjective.
   • Example:
     • "самый большой" means "the biggest."

2. How to Use:

   • This shows the highest level among three or more things.
   • Sentence: "Это самый интересный фильм." means "This is the most interesting film."
