Learn Hardcore Russian: Я точно повторю все новые слова перед контрольной работой. - I will definitely review all the new words before the test.

Повторю is the perfective future form of повторить. In Russian, the perfective aspect emphasizes that the action will be completed (i.e. you will finish reviewing all the words). If you used the imperfective повторять, you’d say я буду повторять все новые слова, which focuses more on the process or habit of repeating rather than its completion before the test.

What does the adverb точно add to the meaning, and could I use a different word?

Точно here means “exactly” or “for sure,” adding a nuance of certainty: “I will definitely go over all the new words.” You could also use обязательно (“ обязательно повторю все новые слова” = “I will certainly review all the new words”) but точно sounds a bit more colloquial.

Why is точно placed before повторю? Can its position in the sentence change?

In Russian, adverbs typically precede the verb they modify, so точно повторю is the most natural order. You could move it for emphasis—Я повторю точно все новые слова…—but that shifts the stress slightly onto все новые слова rather than on your certainty.

Why is все новые слова in the accusative case, and how do I form that?

Повторить is a transitive verb, so its object—все новые слова—takes the accusative. Because слово is an inanimate neuter noun, its accusative plural is identical to its nominative plural: новые слова. The quantifier все likewise has the form все in both nominative and accusative plural.

Does the word все decline, or is it always все?

As a pronoun-adjective meaning “all,” все is invariable in the plural when used before a noun and takes the form все in both nominative and accusative. In other functions (e.g. genitive) or singular, it has different forms: вся, всё, всего, etc.

Can I say новые все слова instead of все новые слова?

No. The standard word order for quantifier + adjective + noun is все новые слова. Swapping them to новые все слова sounds unnatural in Russian.

What case is used with перед контрольной работой, and why? Could I use до контрольной работы instead?

The preposition перед takes the instrumental case, so контрольная работа becomes контрольной работой. You could use до instead, which takes the genitive: до контрольной работы (“before the test”). The nuance is slight—перед often implies “immediately before,” while до can mean “at any time before.”

What exactly is a контрольная работа? How is it different from тест or экзамен?

A контрольная работа is a written classroom test or quiz, typically shorter and less formal than an экзамен (exam). Тест is a loanword that often implies multiple-choice or computer-based testing. Контрольная usually refers to a teacher’s in-class written assignment to check students’ knowledge.

Could I replace повторить with выучить, and what would change?

Yes, выучить means “to learn” (to memorize) rather than just “review.” If you say я выучу все новые слова, you imply you will learn them from scratch. повторить suggests you’ve already encountered them and are doing a revision.

Is the pronoun я mandatory, or can I drop it?

In Russian you can often omit subject pronouns because the verb ending signals the subject. So Точно повторю все новые слова перед контрольной работой is perfectly acceptable and sounds more casual. Including я adds clarity or emphasis (especially in writing).
