Reason and contrast (поэтому, но)

To build longer, more complex sentences, you can use conjunctions to contrast ideas, explain reasons, and show logical results.

Contrasting Ideas with Но

To contrast two statements, use the conjunction но (but). When connecting two complete thoughts, always place a comma before it.

but
но
The bread is fresh, but the cheese is old.
Хлеб свежий, но сыр старый.
She works at home, but we are going to the office.
Она работает дома, но мы едем в офис.

Asking "Why"

Use the question word почему (why) to ask for a reason or explanation.

Giving Reasons with Потому что

To answer "why" or explain the cause of something, use потому что (because). This is a two-word phrase. When it links two parts of a sentence, place a comma immediately before потому.

Expressing Results with Поэтому

While потому что introduces the cause of an action, поэтому (so, therefore) introduces the effect or result. Notice that поэтому is written as a single word. Place a comma before it when it separates clauses.

so (therefore)
поэтому

Building Complex Sentences

Once you are comfortable with these conjunctions, you can chain them together to explain your decisions and debate everyday choices in a single sentence.
