Impersonal Constructions in Russian

In Brief

Russian often expresses a state, need, possibility, or rule without a nominative subject (the ordinary “who or what” form). The person affected usually appears in the dative case (a form often corresponding to “to” or “for”): Мне холодно means “I’m cold,” literally “to me, cold.” Words such as нужно, надо, можно, нельзя and трудно can be followed by an infinitive: Нам нужно идти — “We need to go.”

Overview

An impersonal construction presents a situation without naming an ordinary grammatical subject. English normally supplies one: “I am cold,” “it is dark,” “we need to leave,” or “you may enter.” Russian can instead put the state or necessity at the center of the sentence: мне холодно, темно, нам нужно уходить, можно войти. There is no hidden Russian equivalent of English “it” in these sentences.

This B1 topic brings together several familiar pieces. The dative case marks the experiencer—the person who feels, needs, or judges something. A predicate (the part that says what the situation is) describes the state. An infinitive (the basic “to do” form, such as идти “to go”) names an action when one is needed. In the past and future, the neuter singular forms было and будет locate the whole situation in time.

These patterns are extremely common. They let you talk naturally about comfort, health, weather, difficulty, obligation, permission, and prohibition. For an English speaker, the key habit is to translate the meaning rather than copy English sentence structure: English “I” may become Russian мне, while English “it” may disappear altogether.

How It Works

1. A state with no person: predicate only

For weather, light, temperature, or the general atmosphere, Russian can use a predicate by itself. Words such as холодно “cold,” жарко “hot,” темно “dark,” тихо “quiet,” and ветрено “windy” do not agree with a noun here.

Pattern	Russian	Meaning
Place/time + state word	На улице холодно.	It is cold outside.
State word alone	Темнеет.	It is getting dark.
Impersonal weather verb	Идёт дождь. / Моросит.	It is raining. / It is drizzling.

Do not add оно to stand for English “it.” Оно холодно is not the normal way to say “It is cold.” Notice that идёт дождь does have the nominative noun дождь “rain,” so grammatically it is not built exactly like холодно; learners nevertheless meet both kinds of weather expression together.

2. Dative experiencer + state word

When a particular person experiences the state, put that person in the dative:

dative experiencer + predicate

Person	Dative form	Example
I	мне	Мне холодно. — I’m cold.
you, singular informal	тебе	Тебе удобно? — Are you comfortable?
he / it	ему	Ему скучно. — He is bored.
she	ей	Ей плохо. — She feels ill.
we	нам	Нам интересно. — We find it interesting.
you, plural or formal	вам	Вам понятно? — Is it clear to you?
they	им	Им весело. — They are having fun.

A noun also takes the dative: Анне трудно “Anna finds it difficult,” детям жарко “the children are hot,” моему брату скучно “my brother is bored.” The dative phrase is not a nominative subject, so the predicate does not change for gender or number: мне холодно, ей холодно, детям холодно.

Context can make the experiencer unnecessary: Холодно? may mean “Are you cold?” or “Is it cold?” If the distinction matters, include тебе/вам or a place phrase.

3. Add an infinitive to name the action

Many state words can be followed by an infinitive:

dative experiencer + predicate + infinitive

• Мне трудно говорить об этом. — It is difficult for me to talk about this.
• Ей приятно вас видеть. — She is pleased to see you.
• Нам легко работать вместе. — It is easy for us to work together.

The infinitive is not conjugated for the experiencer. Russian says нам нужно идти, not a form of идти meaning “we go.” Word order can shift for emphasis: Мне трудно это объяснить and Это трудно мне объяснить are possible, but the first is the safest neutral pattern.

4. нужно and надо: need and obligation

Нужно and надо are invariant predicate words: they do not change with the person. The person who needs to act is dative, and the action is infinitive.

Pattern	Example	Meaning
кому + нужно/надо + infinitive	Мне нужно позвонить врачу.	I need to call the doctor.
no stated person	Надо подождать.	We/you/one must wait.
нужно + noun	Мне нужна помощь.	I need help.

The last row is a different agreement pattern. Before an infinitive, impersonal нужно stays нужно: мне нужно работать. With a noun meaning the thing required, short adjective forms agree with that noun: нужен билет (masculine), нужна виза (feminine), нужно время (neuter), нужны документы (plural).

Надо is especially frequent in conversation and occurs mainly with an infinitive. Нужно is neutral and works in both speech and writing. Необходимо expresses stronger or more formal necessity: Необходимо заполнить форму “It is necessary to complete the form.”

5. можно and нельзя: permission, possibility, and prohibition

With an infinitive, можно can mean “may,” “can,” or “it is possible.” Нельзя can mean “must not,” “may not,” or sometimes “cannot,” depending on context.

• Здесь можно фотографировать. — You may take photos here.
• Отсюда можно увидеть море. — You can see the sea from here.
• Здесь нельзя курить. — Smoking is not allowed here.
• Без ключа нельзя открыть дверь. — The door cannot be opened without a key.

A dative phrase identifies the person to whom the permission, prohibition, or possibility applies: Вам можно войти “You may come in”; Ему нельзя кофе “He must not have coffee / coffee is not advisable for him.” In requests, Можно...? is an everyday way to ask permission: Можно открыть окно? “May I open the window?” The speaker is usually understood from context, so мне is often omitted.

6. Past and future: было and будет

In the present, there is normally no form of быть “to be.” For past and future time, use the neuter singular forms было and будет because the construction has no nominative person or thing for the verb to agree with.

Time	Pattern	Example
Present	dative + predicate	Ему трудно. — It is difficult for him.
Past	dative + было + predicate	Ему было трудно. — It was difficult for him.
Future	dative + будет + predicate	Ему будет трудно. — It will be difficult for him.
Past modal	можно/нельзя/нужно было + infinitive	Можно было войти. — It was possible/permitted to enter.
Future modal	можно/нельзя/нужно будет + infinitive	Нужно будет позвонить. — It will be necessary to call.

The usual neutral order is было холодно, нужно было уйти, можно было спросить. Other orders can highlight a particular element, but был/была/были is wrong unless there is an actual nominative noun controlling agreement.

7. Negation: не нужно is not нельзя

These forms express different ideas:

Russian	Core meaning	Example
не нужно / не надо	there is no need; should not	Тебе не нужно спешить. — You don’t need to hurry.
нельзя	forbidden; impossible	Здесь нельзя парковаться. — Parking is not allowed here.
не было / не будет + state	state did not/will not exist	В комнате не было холодно. — It was not cold in the room.

In advice, не надо can also mean “don’t”: Не надо волноваться “Don’t worry / there is no need to worry.” It is generally softer than a direct prohibition with нельзя.

Common Mistakes

Using a nominative pronoun as in English

• Wrong: Я холодно.
• Right: Мне холодно.
• Why: The person experiencing the temperature is dative. There is no adjective agreeing with я in this construction.

Adding an equivalent of English “it”

• Wrong: Оно здесь темно.
• Right: Здесь темно.
• Why: Russian impersonal state expressions do not require a dummy subject corresponding to English “it.”

Making the predicate agree with the experiencer

• Wrong: Ей холодная. / Им холодные.
• Right: Ей холодно. / Им холодно.
• Why: холодно is an invariant predicative form here, not an adjective describing a feminine or plural noun.

Changing нужно before an infinitive

• Wrong: Нам нужны идти.
• Right: Нам нужно идти.
• Why: Before an infinitive, impersonal нужно does not agree with нам. Use нужны only with a plural noun: Нам нужны билеты “We need tickets.”

Confusing no need with prohibition

• Wrong for “You don’t need to come”: Тебе нельзя приходить.
• Right: Тебе не нужно приходить.
• Why: нельзя says coming is forbidden or impossible. не нужно says it is unnecessary.

Using the wrong past form of быть

• Wrong: Мне был трудно. / Нам были нужно уйти.
• Right: Мне было трудно. / Нам нужно было уйти.
• Why: An impersonal past construction uses neuter singular было, regardless of the experiencer’s gender or number.

Usage Notes

Надо is ordinary, frequent spoken Russian; it is not inherently rude. Нужно is similarly common but often feels a little more neutral across spoken and written contexts. Необходимо suits instructions, official notices, and stronger statements of necessity. Tone still depends heavily on context and intonation: Вам надо уйти can sound like practical advice or a firm instruction.

Russian often omits the dative experiencer when it is obvious or when the statement is general. Надо идти may mean “I have to go,” “we should go,” or simply “it is time to go.” Можно войти? normally asks whether the speaker may enter. Add the dative when you need contrast or clarity: Мне можно войти, а ему нельзя “I may enter, but he may not.”

Word order is flexible but not random. Neutral sentences often put known information first: Мне сегодня нужно работать. Moving the infinitive forward can create contrast: Работать мне сегодня не нужно, но я должен ответить на письма “I don’t need to work today, but I must answer emails.” At B1, use the neutral patterns until you have heard enough natural Russian to control these emphasis differences.

Be careful when translating English “can.” Ability learned by a person is often expressed with уметь: Я умею плавать “I can swim.” Situational possibility often uses можно: Здесь можно плавать “You can/may swim here.” Physical or practical ability in a particular situation may use мочь: Я не могу открыть дверь “I can’t open the door.”

Beyond the Basics / Advanced Use

Russian has impersonal verbs and constructions beyond the core state-and-modal patterns. Some take an experiencer in a case other than the dative:

• Меня тошнит. — I feel sick. Here меня is accusative (the object form used after many verbs).
• Мне хочется спать. — I feel like sleeping. Хочется is impersonal and the experiencer is dative.
• Мне не спится. — I can’t sleep / sleep will not come to me. The reflexive-looking -ся form presents the event as outside the person’s control.
• Его знобит. — He has chills. The experiencer is accusative.

These patterns show why “impersonal” does not mean “there is never a person.” It means there is no ordinary nominative subject controlling the sentence. The case required by the predicate or verb must be learned with the expression.

Past можно было + infinitive can describe past permission or opportunity: Там можно было купаться “Swimming was allowed/possible there.” In some contexts it also points to an unrealized option, often translated “could have”: Можно было позвонить “You could have called.” Context and intonation tell the listener whether this is a neutral observation or criticism.

Perfective and imperfective infinitives can change the focus. Здесь нельзя переходить улицу presents crossing as a prohibited activity, while Эту улицу нельзя перейти из-за ремонта means it is impossible to get across this street because of the roadworks. This contrast depends on verbal aspect, but the impersonal frame itself remains unchanged.

A related formal pattern uses a predicative passive participle (a form describing the result of an action): Вход запрещён “Entry is prohibited.” Unlike Здесь нельзя входить, this sentence has the nominative subject вход, and запрещён agrees with it. Notices often use both styles, but their grammar is different.

Practice Tips

1. Build three-way sets. Take one predicate and say it in the present, past, and future: мне трудно — мне было трудно — мне будет трудно. Repeat with холодно, интересно, нужно and можно.
2. Convert English subjects instead of translating them. For “we are hot,” first ask who experiences the state, choose dative нам, then add жарко. Practice all seven dative pronouns with the same predicate.
3. Sort real examples by meaning. While reading signs or listening to dialogue, collect нужно/надо, не нужно/не надо, можно, and нельзя in separate groups. Say whether each example expresses necessity, lack of necessity, permission, possibility, prohibition, or impossibility.
