Questions & Answers about Если бы я не забыл зонтик, моя куртка не стала бы мокрой.

Why are there two бы’s in the sentence?

In Russian counterfactual conditionals (unreal “if” sentences), бы typically appears in both the if-clause and the result clause:

• Если бы я не забыл… = If I hadn’t forgotten…
• …не стала бы мокрой = …would not have become wet
  English often uses one “would,” but Russian commonly marks both parts with бы.

What exactly does Если бы mean, and how is it different from Если without бы?

• Если бы introduces a counterfactual / unreal condition (something that did not happen).
• Если (no бы) is for a real or possible condition (something that may happen).
  So Если бы я не забыл зонтик… implies you did forget the umbrella.

Why is there a comma after зонтик?

Russian normally uses a comma to separate the conditional clause from the main clause:

• Если бы … , …
  This is standard punctuation even when the clauses are short.

Why is it я не забыл (past tense) if English uses something like “hadn’t forgotten”?
