Questions & Answers about В нашей группе семьдесят студентов.

Why is there no verb “to be” (быть / есть) in this sentence?

In Russian, the present‑tense form of быть (“to be”) is usually omitted in simple equational or existential sentences.

So instead of literally saying “In our group there are seventy students,” Russian typically just says:

• В нашей группе семьдесят студентов.

You can add есть:

• В нашей группе есть семьдесят студентов.

This is grammatically correct, but есть adds a slight nuance of “there exists / there really are,” and is more common when you want to emphasize existence, contrast, or new information. In neutral statements like this one it’s very often left out.
