Questions & Answers about Вряд ли оса залетит в комнату, если окно закрыто.

What does вряд ли mean, and why is it written as two words?

Вряд ли is a fixed expression meaning hardly, unlikely, or probably not.

In this sentence, Вряд ли оса залетит... means It’s unlikely that a wasp will fly in...

It is normally written as two words:

• вряд — not really used on its own in modern speech
• ли — a particle

So it is best to learn вряд ли as one set phrase.

Why is there no не with залетит?

Because вряд ли already gives the sentence a negative meaning: unlikely.

So:

• Вряд ли оса залетит = The wasp is unlikely to fly in

If you added не, you would change the meaning:

• Вряд ли оса не залетит = It’s unlikely that the wasp won’t fly in
  which suggests it probably will fly in.

So in the original sentence, no не is needed.

Why is оса in the nominative case?
