Embedded Yes-no Question with Ли

The particle ли is used to create indirect yes-no questions (e.g., 'I don't know whether he is home'). It acts as an enclitic, meaning it must follow the specific word being questioned.

How It Works

In Russian, the particle ли is widely used to report yes-no questions. While this lesson focuses on indirect questions, ли is also used in direct questions (e.g., Есть ли жизнь на Марсе?) and fixed expressions like вряд ли and чуть ли не. It cannot be used in indirect questions that already contain a question word such as кто (who), где (where), or когда (when).

1. Word Order and Focus
The word or phrase that is the 'focus' of the question must be moved to the front of the subordinate clause, and ли follows the first fully stressed word of that focused phrase. This focus can be a verb, a noun, an adjective, or an adverb. If the focus is a prepositional phrase, ли follows the first stressed word after the preposition (e.g., в Москву ли, not в ли Москву). If the noun has an adjective, ли follows the adjective, not the noun (e.g., в новую ли Москву, not в новую Москву ли).

  • Action: Я не знаю, придёт ли он. (I don't know if he will come.)
  • Person: Я не знаю, он ли придёт. (I don't know if it is he who will come.)
  • State/Adjective: Он спросил, готов ли обед. (He asked if the lunch was ready.)
  • Manner/Adverb: Трудно сказать, быстро ли он бегает. (It's hard to say if he runs fast.)

2. No Tense Backshifting
A crucial difference from English is that Russian does not change the tense in indirect questions. You must preserve the tense of the original thought. If the original question was 'Are you working?' (present), the correct English translation is 'He asked if I was working', but because Russian does not backshift, the Russian literally translates to 'He asked if I am working' (Он спросил, работаю ли я).

3. Pronoun Shifting
While the tense does not change in reported speech, pronouns must shift to reflect the perspective of the reporter. As seen in the previous example, the original 'you' (ты) changes to 'I' (я) when reporting what was asked of you.

4. Punctuation
You must always place a comma before the subordinate clause starting with the focus word and ли. This separates the introductory verb (like 'ask', 'know', 'wonder') from the question itself.

5. Interrogative vs. Conditional
English speakers often confuse ли with если. Use ли when you are expressing uncertainty or asking a yes-no question ('whether'). Use если only for conditions ('in the event that'). For example, compare the condition Если пойдёт дождь... (If it rains...) with the indirect question Я не знаю, пойдёт ли дождь (I don't know if it will rain). Note that если is used for conditions in all tenses (present, past, and future), not just future conditions.

6. Negation, Polite Offers, and 'или нет'
If the indirect question is negative, ли still follows the verb, and the particle не stays attached to that verb: Он спросил, не забыл ли я ключи. Negative indirect questions are also frequently used for polite offers or requests, which translate to positive sentences in English (e.g., Он спросил, не хочу ли я чаю translates to 'He asked if I wanted some tea'). This structure is also very common in polite direct questions starting with Не... ли, such as Не знаете ли вы...? (Do you happen to know...?) or Не подскажете ли...? (Could you tell me...?). Additionally, indirect questions with ли are often paired with или нет (whether or not) at the end of the clause (e.g., Я не знаю, придёт ли он или нет).

7. Pronunciation
The particle ли is an unstressed enclitic. It has no stress of its own and is pronounced as if it were an extra syllable attached to the word that precedes it.

8. Register
Using ли is the completely standard and normal way to form indirect questions across all registers, including everyday informal conversation. It is only considered formal when used in direct questions. To become proficient in standard Russian, you should use ли confidently in both speech and writing.

Examples (5)

  1. Я хотел уточнить, готов ли мой заказ.

    I wanted to clarify whether my order is ready.

    Word by Word: I wanted to clarify, ready [particle] my order.

    Here, 'готов' (ready) is the focus, so 'ли' follows it immediately.

  2. Трудно сказать, хорошая ли это идея.

    It is hard to say whether this is a good idea.

    Word by Word: Hard to say, good [particle] this idea.

    The adjective 'хорошая' is moved to the front of the clause to be the focus of the question.

  3. Она поинтересовалась, не забыл ли я ключи.

    She wondered whether I had forgotten the keys.

    Word by Word: She wondered, not forgot [particle] I keys.

    In negative questions, 'ли' follows the negated verb.

  4. Интересно, сегодня ли он приедет.

    I wonder if it's today he's arriving.

    Word by Word: Interesting, today [particle] he will arrive.

    By placing 'ли' after 'сегодня', the speaker emphasizes that the date is the specific point of uncertainty.

  5. Мы не знали, дома ли они.

    We didn't know whether they were home.

    Word by Word: We not knew, at home [particle] they.

    The word 'дома' (at home) is the focus of the inquiry.

Common Mistakes

  • Using 'если' for indirect questions.

    Я не знаю, если он придёт.
    Я не знаю, придёт ли он.

    'Если' is only for conditions ('If it rains, I'll stay'). For 'whether', you must use 'ли'.

  • Using the past tense when the question was about now.

    Different MeaningОн спросил, был ли я голоден.
    Он спросил, голоден ли я.

    «Он спросил, был ли я голоден» is correct, but it asks whether I had been hungry earlier. Russian keeps the tense of the original question: if he asked «Ты голоден?», say «Он спросил, голоден ли я».

  • Omitting the comma before the subordinate clause.

    Я хотел узнать готов ли обед.
    Я хотел узнать, готов ли обед.

    In Russian, a comma is mandatory to separate the main clause from the subordinate clause containing 'ли'.
