The past tense: four forms

The Russian past tense is the reward for surviving the present. Six person endings shrink to four forms, those four forms are built by one rule, and a single tense does the work that English spreads across five.

How to form the Russian past tense

Take the infinitive, remove the -ть, and add one of four endings:

• -л for a masculine subject
• -ла for a feminine subject
• -ло for a neuter subject
• -ли for any plural subject

That is the whole rule for the large regular majority. Here it is on five verbs from the first chapters of the course:

Compare that with the present tense, which needs two conjugation patterns and six endings each. The past does not care which conjugation a verb belongs to. Говорить and делать, second and first conjugation, take identical endings.

Gender, not person

The past tense ignores person completely. Here is how the pronouns line up:

Two consequences follow, and both are worth taking seriously.

First, the pronoun stops being optional. In the present, знаю already says I know and the я can go. In the past, знал could be I, you or he, so Russians keep the pronoun: Я ду́мал, что ты зна́ешь (I thought you knew). Drop it and nobody knows who you mean.

Second, the verb announces the speaker's gender. A woman cannot tell you where she was yesterday without the ending saying so. Where were you? is Где ты был? to a man and Где ты была́? to a woman. Many textbook dialogues are written from a male point of view, so women learning Russian pick up the masculine forms by imitation and have to unlearn them. If you are a woman, say every example in this article with -ла and get the habit early.

The historical reason is tidy: the Russian past was once a participle, closer to an adjective than to a verb, and adjectives agree with gender and number, not person. The past kept the adjective's agreement and never grew person endings.

Вы is always plural

Polite вы takes -ли, full stop. Talking to your teacher, a stranger or a single elderly woman on a train, it is Вы бы́ли пра́вы (you were right), never вы была. This is a rule without exceptions, and it is also one of the most common errors in learner Russian, because the learner is looking at one person and reaching for the singular. The grammar is looking at the pronoun.

The neuter form is less rare than it looks

You will seldom say оно about a person, so -ло looks like the form you can skip. It is not, because it has three other jobs.

Neuter nouns, obviously: Письмо́ пришло́ вчера́ (the letter came yesterday), Вре́мя прошло́ (time passed).

Sentences with no subject at all, which Russian uses constantly for weather, states and feelings. The verb has nothing to agree with, so it defaults to neuter:

Бы́ло по́здно. - It was late.

Мне бы́ло тру́дно. - It was hard for me.

На́до бы́ло сказа́ть. - I should have said. (literally it was necessary to say)

The question word что, which is grammatically neuter: Что случи́лось? and Что произошло́? both mean what happened? and both end in -ло. Its partner кто goes the other way and takes the masculine regardless of who is being asked about, so Кто э́то сказа́л? is correct even when everyone in the room knows it was a woman.

Быть comes back in the past

In the present, the verb to be simply vanishes: Я до́ма is I am at home. In the past it returns, and it has to agree like any other past verb:

The trap is in the possessive. Russian says I have a brother as at me is a brother, and in the past the verb agrees with the thing possessed, not the owner. So a woman says У меня́ был брат (masculine, because брат is), and a man says У меня́ была́ иде́я (feminine, because идея is). The owner's gender is irrelevant here, which is exactly backwards from what the previous section trained you to do.

And the negative is fixed: absence always takes не бы́ло plus the genitive. У меня́ не бы́ло вре́мени means I did not have time, whatever the gender of anyone involved.
