Learn Hardcore Russian: Мы празднуем успех.

The verb is празднуем, which means “we celebrate.” It’s the first person plural form of праздновать, an imperfective verb meaning “to celebrate” or “to observe.”

What tense and aspect does празднуем convey?

Празднуем is in the present tense and imperfective aspect. That means it describes an ongoing or habitual action: “we are celebrating” or “we celebrate,” rather than a completed event.

How would you express a completed action “we celebrated success”?

To show a completed action, use the perfective verb отпраздновать in the past tense:
• Masculine/All genders plural: Мы отпраздновали успех.
This means “we celebrated success” (and finished celebrating).

Why is успех unchanged in the sentence? What case is it?

Успех is the direct object of праздновать, so it takes the accusative case. Because успех is a masculine inanimate noun, its accusative form is identical to its nominative form (успех).

Do you need a preposition for “celebrate success” in Russian?

No preposition is used here. In English we say “celebrate success” with no extra words either. In Russian you simply put the object (успех) directly after the verb (празднуем).

What’s the difference between праздновать and отмечать?

Both can mean “to celebrate,” but:
• праздновать focuses on the festive act itself (partying, ceremonies).
• отмечать can also mean “to mark” or “to note” (for example, marking an anniversary) and is stylistically a bit more neutral or formal.

Where is the stress in успех?

The stress falls on the second syllable: успе́х (us-PEKH).
