The Russian past tense.

How the past tense is formed

Take the infinitive. Drop the -ть. Add a gender/number ending.

Example with читать (to read):

• читать → читал (he read / I read, male speaker / you read, male)
• читать → читала (she read / I read, female / you read, female)
• читать → читало (it read, neuter subject - rare)
• читать → читали (we read / you all read / they read)

The pronoun never changes the ending. A man and a woman both say "я" for "I," but the verb form tells you which one is speaking:

• Я читал книгу. - I was reading a book. (male speaker)
• Я читала книгу. - I was reading a book. (female speaker)
• Мы читали книгу. - We were reading a book. (any gender mix)

The four past-tense endings

The stress can shift between infinitive and past forms (and between past forms themselves). Some verbs keep stress on the stem (читал, читала); others shift to the ending in the feminine (был → была́, жил → жила́). When in doubt, look up the verb in a dictionary - stress is a per-verb fact, not a rule.

Aspect in the past: imperfective vs perfective

Russian verbs come in aspect pairs: imperfective for ongoing or repeated actions, perfective for completed single events. Both aspects have a past tense, and the choice changes the meaning.

• Я читал книгу. (imperfective) - I was reading a book. (process, no result implied)
• Я прочитал книгу. (perfective) - I read the book (and finished it).
• Она делала домашнее задание. - She was doing her homework.
• Она сделала домашнее задание. - She did / finished her homework.

The imperfective past describes the process, the duration, or a habit. The perfective past describes a single completed event with its result. Both forms follow the same -л/-ла/-ло/-ли endings.

Irregular past forms worth memorising

A small set of common verbs drop the -л in the masculine singular, or have a stem that changes in the past. These show up constantly, so it pays to internalise them early.

The pattern: when the masculine singular doesn't end in -л, the other three forms still do (мог, могла, могло, могли). The feminine, neuter, and plural restore the regular ending.

Past tense of reflexive verbs (-ся / -сь)

Reflexive verbs ending in -ся keep their reflexive suffix in the past, but the form of the suffix depends on whether the past ending ends in a consonant or vowel:

• After a consonant (-л): -ся  → учился (he studied)
• After a vowel (-ла, -ло, -ли): -сь  → училась, училось, учились

Common pitfalls

Trying to agree with the person

English speakers often try to match the past form to the speaker as if it were "I-was, you-were, he-was." Russian doesn't. The verb form mirrors gender and number of the subject, not the person. A man saying "I read" says я читал; a woman says я читала. Same "I," different verb.

Using imperfective when the result matters

If the action produced a result you care about, use the perfective: я прочитал книгу = "I read the book" (finished it). If you're describing duration or process: я читал книгу два часа = "I read the book for two hours" (the time spent matters, not whether you finished).

"He went" without context

The verb шёл (he went, walking, in one direction) is unidirectional - it describes a single trip in progress. ходил (he went, multidirectional past) often means "went and came back." So Он шёл в школу describes the journey itself, while Он ходил в школу usually means "he went to school (and returned)." See the verbs of motion guide for the full split.

The negative existential trap

"He wasn't home" is Его не было дома - not он не был дома (though that's also grammatical, with a different nuance: "he didn't happen to be home" vs "he wasn't at home"). The default for negative location uses не было with the genitive of the subject.

Frequently asked questions

How do you form the past tense in Russian?

Take the infinitive, drop the -ть, and add one of four endings depending on the subject. -л for masculine singular (он читал), -ла for feminine (она читала), -ло for neuter (оно читало), -ли for plural (они читали). The endings reflect gender and number, not person. A man saying 'I read' uses читал; a woman uses читала. Same pronoun я, different verb.

Why doesn't the Russian past tense agree with 'I' or 'you'?

Russian past-tense verbs are historically participles, not finite verb forms - that's why they behave like adjectives, agreeing with the subject in gender and number rather than person. Modern Russian preserves this. The pronoun (я, ты, он, она, мы, etc.) tells you who's acting; the verb ending tells you their gender and number. It's an unusual feature for European-language learners but consistent across every verb.

What's the difference between читал and прочитал?

Both are past tense, but the aspect differs. Читал is imperfective: it describes the process, the duration, or a habit ('I was reading,' 'I used to read'). Прочитал is perfective: it describes a single completed action with a result ('I read [through] the book,' implying you finished it). Choose imperfective when the process matters, perfective when the result matters. See the verbal aspect page for the full rules.

Are there irregular past-tense verbs in Russian?

A small set of common verbs has irregular past forms. The masculine singular often drops the -л: идти becomes шёл (not 'идл'), мочь becomes мог, нести becomes нёс. The feminine, neuter, and plural restore the regular pattern: шла, шло, шли. The verbs to memorise first: идти/шёл, мочь/мог, нести/нёс, вести/вёл, везти/вёз, есть/ел, быть/был, умереть/умер.

How do reflexive verbs form the past tense?

Reflexive verbs (ending in -ся) follow the same -л/-ла/-ло/-ли pattern, but the reflexive suffix shifts depending on whether the past ending ends in a consonant or a vowel. After the consonant -л, the suffix is -ся: учился (he studied). After the vowels -ла, -ло, -ли, the suffix is -сь: училась, училось, учились. The full pattern: учился, училась, училось, учились.

How do you say 'I wasn't home' in Russian?

Two options. The literal version is 'Я не был дома' (or 'не была' for a female speaker) - meaning 'I happened not to be home / I didn't go home.' But the more idiomatic Russian for 'I wasn't home (at the relevant moment)' is the impersonal 'Меня не было дома' - literally 'Of me there was not [at] home.' The construction uses the genitive of the absent person plus не было (neuter singular, always).

What word order does the Russian past tense use?

Russian word order is flexible because the verb form encodes the subject's gender and number. The neutral order is subject - verb - object, like English: 'Маша читала книгу' (Masha was reading a book). But you can move pieces for emphasis: 'Книгу читала Маша' (it was Masha who was reading the book). The verb-form ending tells you who did what; the word order tells you what's being emphasised.
