Verbs — Past & Future Tense
In a nutshell
- Past tense agrees with gender and number of the subject, not person — one set of four endings covers every "I/you/he/she/we/they."
- A handful of common verbs have irregular past stems: идти́ → шёл/шла́/шло́/шли́, мочь → мог/могла́/могло́/могли́.
- Compound future (бу́ду + imperfective infinitive) works like English "will be doing" — full paradigm below.
- Perfective verbs have their own future form that looks like a present-tense conjugation but means "will finish" — the full explanation is Lesson 9: Aspect.
Past tense: built from gender and number, not person
This is the single biggest structural difference from present tense: Russian past-tense verbs don't care whether the subject is "I," "you," or "she" — they only care whether the subject is masculine, feminine, neuter, or plural. Strip the -ть off the infinitive and add one of four endings:
| Subject gender/number | Ending | чита́ть → | говори́ть → |
|---|---|---|---|
| Masculine singular (я/ты/он) | -л | чита́л | говори́л |
| Feminine singular (я/ты/она́) | -ла | чита́ла | говори́ла |
| Neuter singular (оно́) | -ло | чита́ло | говори́ло |
| Plural (мы/вы/они́) | -ли | чита́ли | говори́ли |
Я чита́л кни́гу. — lit. "I read-masc book-ACC." — "I read a book." (said by a male speaker)
Я чита́ла кни́гу. — lit. "I read-fem book-ACC." — "I read a book." (said by a female speaker)
Они́ говори́ли по-ру́сски. — lit. "They spoke-plural in-Russian-way." — "They spoke Russian."
Notice that "я" and "ты" each need you to supply the gender based on who's talking — the verb form itself doesn't distinguish 1st from 2nd person at all. This is genuinely simpler than present tense in one sense (only four forms to learn instead of six) — you just have to retrain the reflex of "which person" into "which gender."
Irregular past stems
A few very common verbs don't just glue -л onto the infinitive stem — the masculine form in particular often drops the -л entirely when the stem ends in a consonant.
идти́ (to go, on foot) → шёл/шла́/шло́/шли́
| Gender/number | Form |
|---|---|
| Masculine | шёл |
| Feminine | шла́ |
| Neuter | шло́ |
| Plural | шли́ |
Он шёл домо́й. — lit. "He went(masc) homeward." — "He was walking home."
Notice the stress moves onto the ending in feminine/neuter/plural (шла́, шло́, шли́) but sits on the stem in masculine (шёл) — this shifting stress pattern is common among irregular past-tense verbs, so don't assume stress stays put.
мочь (to be able to) → мог/могла́/могло́/могли́
| Gender/number | Form |
|---|---|
| Masculine | мог |
| Feminine | могла́ |
| Neuter | могло́ |
| Plural | могли́ |
Я не мог позвони́ть тебе́. — lit. "I not could to-call you." — "I couldn't call you." (male speaker)
Notice мог, not "могл" — verb stems ending in a consonant (г here) simply skip the -л in the masculine form, because "могл" is impossible to pronounce cleanly in Russian. This masculine-drops-л pattern shows up in a small set of consonant-stem verbs; treat each one as vocabulary to memorize rather than trying to derive it from a universal rule.
есть (to eat) → ел/е́ла/е́ло/е́ли
| Gender/number | Form |
|---|---|
| Masculine | ел |
| Feminine | е́ла |
| Neuter | е́ло |
| Plural | е́ли |
Мы е́ли пи́ццу вчера́. — lit. "We ate pizza-ACC yesterday." — "We ate pizza yesterday."
быть (to be) — был/была́/бы́ло/бы́ли
быть is the single most-used irregular past verb, because it forms half of common negative constructions.
| Gender/number | Form |
|---|---|
| Masculine | был |
| Feminine | была́ |
| Neuter | бы́ло |
| Plural | бы́ли |
Вчера́ я был до́ма. — lit. "Yesterday I was(masc) at-home." — "Yesterday I was home." (male speaker)
Она́ была́ на рабо́те. — lit. "She was(fem) at work-PREP." — "She was at work."
Notice the stress: feminine была́ moves the stress to the ending, but masculine/neuter/plural keep it on the stem (был, бы́ло, бы́ли). This is a very common and very tested stress pattern — drill it separately from the meaning.
Negative past of быть is special. The negative particle не combines with был/была́/бы́ло/бы́ли, but in the neuter/impersonal negative form, the stress always jumps to не, and the form is не́ было regardless of what's being negated:
У меня́ не́ было вре́мени. — lit. "At me not-was time-GEN." — "I didn't have time."
Его́ не́ было до́ма. — lit. "Him not-was at-home." — "He wasn't home."
Compare this to the plain negative of the masculine/feminine/plural forms, which behave normally (не был, не была́, не́ были) — но не́ было is the fixed, frozen "there wasn't/there wasn't any" form and is worth memorizing as its own chunk.
Future tense: two systems
Russian doesn't have one future tense — it has two, and which one you use depends on aspect (imperfective vs. perfective). This lesson introduces the shape of both; Lesson 9: Aspect is where you'll learn to actually choose between them with confidence.
Compound future — for imperfective verbs
Built from a conjugated form of быть (to be) plus an imperfective infinitive. This describes an ongoing action, a process, or something you'll be doing/doing repeatedly in the future — think English "I will be reading" or plain "I will read [as an activity]."
| быть | + infinitive | |
|---|---|---|
| я | бу́ду | бу́ду чита́ть |
| ты | бу́дешь | бу́дешь чита́ть |
| он/она́/оно́ | бу́дет | бу́дет чита́ть |
| мы | бу́дем | бу́дем чита́ть |
| вы | бу́дете | бу́дете чита́ть |
| они́ | бу́дут | бу́дут чита́ть |
Я бу́ду чита́ть весь ве́чер. — lit. "I will-be to-read whole evening." — "I'll be reading all evening."
Мы бу́дем жить в Москве́. — lit. "We will-be to-live in Moscow-PREP." — "We're going to live in Moscow."
The infinitive after бу́ду etc. must be imperfective — this pairing (a conjugated бу́ду + imperfective infinitive) is the only correct way to build this kind of future. You cannot say "бу́ду прочита́ть" — that mixes a compound-future construction with a perfective infinitive, and it's simply ungrammatical.
Perfective future — for perfective verbs
Perfective verbs (like прочита́ть, "to read through / finish reading") don't use бу́ду at all. Instead, you conjugate the perfective verb directly, using endings that look exactly like present-tense endings — but because the verb is perfective, the meaning is automatically future ("will finish," "will complete"), never "am doing right now."
Я прочита́ю кни́гу за́втра. — lit. "I through-read(future) book-ACC tomorrow." — "I'll finish reading the book tomorrow."
Он напи́шет письмо́. — lit. "He through-write(future) letter-ACC." — "He'll write the letter (and finish it)."
This might feel confusing right now — the same verb shape you'd expect to mean "I read [now]" instead means "I will finish reading," simply because the verb is perfective and perfective verbs have no present tense at all. That's exactly the topic of the next lesson: Lesson 9: Aspect goes deep on why Russian splits verbs into imperfective/perfective pairs, and how to pick the right one for compound vs. perfective future, and for past tense too.
Practice
- Conjugate чита́ть in the past tense for a female subject "она́."
- Conjugate говори́ть in the past tense for the plural subject "мы."
- Give the past tense of быть for a neuter subject ("оно́ ... до́ма").
- Translate: "I didn't have money." (use у меня́ + не́ было + де́нег)
- Give all four past-tense forms of идти́.
- Give all four past-tense forms of мочь. Why is there no "л" in the masculine form?
- Conjugate бу́ду говори́ть for "ты" and "они́."
- Translate using compound future: "We will be working tomorrow." (рабо́тать)
- True or false: "бу́ду прочита́ть" is a correct way to say "I will read (and finish) it." Explain.
- Translate: "She ate breakfast." (use есть, за́втрак, feminine subject)
- Fill in the blank: Вчера́ он ___ (быть) на рабо́те.
- Explain in one sentence why "я чита́л" and "я чита́ла" mean the same thing in English but are different words in Russian.
Answers
- чита́ла — feminine singular past ending -ла.
- говори́ли — plural past ending -ли, same for any plural subject regardless of person.
- бы́ло — neuter singular past of быть, stress on the stem.
- У меня́ не́ было де́нег. — fixed negative-past-of-быть construction, always "не́ было" + genitive.
- шёл, шла́, шло́, шли́ — irregular стем, stress shifts to the ending except in masculine.
- мог, могла́, могло́, могли́ — no masculine "л" because the consonant-ending stem (мог-) can't take -л smoothly; this is a memorized irregularity.
- ты бу́дешь говори́ть, они́ бу́дут говори́ть — бу́ду conjugated for person, plus the plain imperfective infinitive.
- Мы бу́дем рабо́тать за́втра. — compound future, imperfective рабо́тать describes the activity itself.
- False. Perfective verbs never combine with бу́ду — a perfective verb is conjugated directly (я прочита́ю) to express future meaning.
- Она́ е́ла за́втрак. — irregular есть, feminine past form.
- Вчера́ он был на рабо́те. — masculine singular past of быть.
- Past tense agrees with the gender of the speaker/subject, not with "I" as a fixed grammatical person — so a male and female speaker both saying "I read" use different verb forms.
