In Russian, there are some special prefixes that can change the verb "строить," which means "to build."

These prefixes are important because they help show whether an action is still happening or if it is completed.

Let’s check out some key prefixes and what they mean:

1. по-: When you see "построить," it means to finish building something.

   • Example: "Я построю дом." (I will build a house.)

2. с-: The prefix "с-" leads to "сстроить," but it’s not used often. You might hear "состоять," which means to build something together or make it from different parts.

   • Example: "Мы составим проект." (We will put together a project.)

3. за-: When you add this prefix, you get "застроить," which means to fill in or build over a space.

   • Example: "Город застроен." (The city has been built up.)

4. у-: With "устроить," this means to arrange or set something up.

   • Example: "Она устроит выставку." (She will organize an exhibition.)

5. вы-: If you see "выстроить," it means to build something carefully or to create it in a specific shape.

   • Example: "Мы выстроим баррикады." (We will build barricades.)

Try using these prefixes to make your own sentences! Doing this can help you understand what they mean even better!
