Russian grammar, explained.
Russian grammar runs on endings. Words change shape to show their job in a sentence, so the meaning lives in the endings, not the word order. Two systems do most of the work: the case system for nouns and the aspect system for verbs. This page is the map.
Russian is an inflected language. The ending of a word tells you its grammatical job, so книгу is "book" as an object no matter where it sits in the sentence. Learn the endings and the patterns that trigger them, and the rest of the grammar follows. There are no articles (no "a" or "the") and no continuous tenses to worry about.
How Russian grammar works
Three features shape almost everything in Russian grammar:
- Endings carry meaning. Nouns, adjectives, and pronouns change their endings depending on their role. The same word has different forms for subject, object, possession, and so on.
- Word order is flexible. Because endings show who does what, you can reorder a sentence for emphasis without losing the meaning. The neutral order is subject-verb-object, but it bends freely.
- No articles, three genders. Russian has no "a" or "the." Every noun is masculine, feminine, or neuter, and that gender controls which endings it takes.
Master two systems and you have the backbone of the language: how nouns decline (the cases) and how verbs work (aspect and conjugation).
The case system
Russian has 6 cases. Each one marks a different role, and each changes the endings of nouns, adjectives, and pronouns. This is the part English speakers find newest, and the highest-leverage thing to learn.
- Nominative - the subject and dictionary form (кто? что?).
- Accusative - the direct object and direction (кого? что?).
- Genitive - possession, absence, and "of" (кого? чего?).
- Dative - the indirect object, age, and feelings (кому? чему?).
- Instrumental - the means or "with" (кем? чем?).
- Prepositional - location and "about" (о ком? о чём?).
Start with the full overview, then go case by case. The cases cheat sheet puts every ending on one page.

Russian verbs carry more information than English ones, but there are fewer moving parts than the cases. Three things matter most:
Aspect: the big one
Almost every Russian verb comes in a pair: imperfective (ongoing, repeated, unfinished) and perfective (completed, one-time, result-focused). Choosing the right one is the central skill of Russian verbs. See verbal aspect for the full picture.
Conjugation
Verbs change their endings for person and number, following two main patterns (conjugation classes I and II). The verb conjugation guide has the tables, and the 50 essential verbs covers the ones you need first.
Tense
Russian has just three tenses: past, present, and future. The present exists only for imperfective verbs; aspect decides how the future and past are formed. There are no continuous or perfect tenses like in English.
Gender and agreement
Every Russian noun has one of three genders, and you can usually read it off the nominative ending: a consonant means masculine (стол), -а/-я means feminine (книга), -о/-е means neuter (окно). The soft sign -ь is the one ambiguity and must be learned per word.
Gender matters because everything around the noun agrees with it. Adjectives, possessives, and past-tense verbs all change to match their noun in gender and number: красивый дом (m.), красивая книга (f.), красивое окно (n.). Get the gender right and agreement falls into place.
Word order
Because endings do the heavy lifting, Russian word order is far freer than English. The default is subject-verb-object, but you can move words around to shift emphasis, usually putting the most important information last.
- Я люблю тебя. - I love you. (neutral)
- Тебя я люблю. - It's you I love. (emphasis on "you")
Both are correct because тебя is accusative either way. Word order changes the emphasis, not the grammar.
Where to start
Tackling Russian grammar in the right order keeps it manageable. A sensible path:
- 1. Nominative + present tense. Subjects and basic verbs let you make simple sentences right away (Я читаю, Он студент).
- 2. Accusative. Direct objects unlock most everyday sentences (Я читаю книгу).
- 3. The rest of the cases. Prepositional and genitive next, then dative and instrumental.
- 4. Aspect. Once you can build sentences, start choosing imperfective vs perfective.
Slova teaches grammar this way: every word shows up in its real forms, in context, so the patterns stick instead of staying abstract.
Russian grammar is front-loaded. The cases look intimidating at first, but they are a finite, learnable system, and once they click, the language becomes predictable. There are no irregular plurals scattered everywhere like in English, no tense soup, no articles to second-guess.
The learners who stall are usually the ones who memorized hundreds of dictionary-form words but never learned how those words change. The grammar is what turns vocabulary into sentences.
Slova builds grammar into every word you learn.
You don't memorize endings in a vacuum. You see книга become книгу, книги, книге in real sentences, and the case system becomes second nature. Cases, conjugation, and aspect, in context, from day one.
