The Russian Particle «ли»: How to Ask Yes/No Questions

The particle ли does one job: it turns a statement into a yes/no question and quietly points at the exact word you're asking about. English has no word for this — we do the same thing with word order and tone of voice — which is why it looks unfamiliar at first. The good news: there's just one rule, and once you have it, ли is easy to use.

Let's take it step by step.

How «ли» works: the one rule

ли comes right after the word you're asking about. It can never start a sentence — it always leans on the word before it.

So the trick is simple: look at the word right before ли — that's what the question is really about. Keep that idea in mind. Everything below is just this one rule in different situations.

«Ли» can move the spotlight

This is my favourite part, because it shows how flexible ли is. Watch what happens when we move it around the sentence:

Same words, same ли — but each version asks about something different. The spotlight always lands on the word just before ли.

Asking yes/no questions with «ли»

In a normal yes/no question, you have two natural options in Russian:

• Ты был в Москве́? = Был ли ты в Москве́? — Have you been to Moscow?

Both are completely normal, everyday Russian. Native speakers use ли all the time — it isn't stiff or old-fashioned. It just sounds a little more deliberate, and it makes the question crystal clear.

And here's a small gift: Russian question intonation can be tricky for learners. Ли gives you a clear, reliable way to ask a yes/no question without worrying about getting the melody exactly right.

So how do you build one? For a plain yes/no question, lead with the verb: move it to the front, attach ли, and let the rest of the sentence follow. Why the verb? Because it's the thing you're really asking about — did it happen, yes or no?

• Он говори́т по-англи́йски? → Говори́т ли он по-англи́йски? — Does he speak English?
• У тебя́ есть вре́мя? → Есть ли у тебя́ вре́мя? — Do you have time?

What can «ли» attach to?

Here's the part that surprises almost everyone. Ли doesn't only follow verbs. Whatever word you're asking about goes first, and ли sits right behind it — and "that word" can be several different things:

• A verb (the everyday case): Говори́т ли он по-ру́сски? — Does he speak Russian?
• Есть, for "have" or "there is":
  • Здесь есть Wi-Fi. → Есть ли здесь Wi-Fi? — Is there Wi-Fi here?
  • У тебя температу́ра. → Есть ли у тебя температу́ра? — Do you have temperature/fever? (Russians often drop есть in the plain statement, but in the ли-question it comes back and takes the ли.)
• Modal words like мо́жно, ну́жно, на́до:
  • Мо́жно ли здесь фотографи́ровать? — Is it OK to take photos here
  • Ну́жно ли брать па́спорт? — Do I need to bring my passport?
• An adjective — yes, really: Он краси́вый. → Краси́вый ли он? — Is he handsome? (The short form works too: Краси́в ли он?)
• Even an adverb: Далеко́ ли до це́нтра? — Is it far to the centre?

The rule never changes: the word in the spotlight comes first, and ли follows. It just catches people off guard that the spotlight can land on an adjective or on мо́жно, not only on a verb.

«Ли» = "whether" in Russian (indirect questions)

Now the most important use — and here ли is not optional. When you report a question inside another sentence (an indirect question), English uses whether or if. Russian uses ли:

• Я не зна́ю, придёт ли он. — I don't know whether he will come.
• Спроси́, мо́жно ли здесь паркова́ться. — Ask whether parking is allowed here.
• Ва́жно, понима́ют ли студе́нты пра́вило. — It matters whether the students understand the rule.

You can't drop ли here — it's simply how Russians build these sentences. The move is the same as before: after the comma, lead with the verb (or мо́жно, есть, and so on), then ли.

«Ли» vs «если» — the mistake almost everyone makes

Both ли and е́сли can be translated as "if" in English, so learners constantly mix them up. But they do completely different jobs:

Here's a test that works almost every time: try replacing "if" with "whether" in your English sentence. If "whether" fits → use ли. If it doesn't (it's a real condition) → use е́сли.

"I'll stay home whether it rains" — no, that's wrong → so it's е́сли. "I don't know whether it will rain" — yes, that works → so it's ли. Keep this little test handy and you'll avoid the most common ли mistake there is.

One habit I pass on to every student: е́сли loves company — it usually comes with то in the second half. Е́сли…, то… — literally if…, then…. Keeping the то there makes the two halves lock together. (You can drop the то, and in casual speech people often do — but while you're learning, keep it: it makes the sentence impossible to misread.)

And if you want to meet the unreal kind of "if" — Е́сли бы шёл дождь, я бы оста́лся до́ма (If it were raining, I'd stay home) — that's a different little word, бы. It's a close cousin of ли (both lean on the word in front, and neither can open a sentence), and I've written a full guide to it in The Russian Subjunctive: Just Add бы. Worth reading the two together.

When «или» takes over

Here's a subtle one, because it changes what you see on the page. When a sentence already sets up a clear either/or with и́ли — especially the pattern … и́ли нет — the ли often disappears. It isn't missing by accident: и́ли is already asking "yes or no?", so the ли becomes optional and quietly steps aside.

• Хо́чешь ты э́того и́ли нет — Whether you want it or not

By everything above, you'd expect Хо́чешь ли ты э́того и́ли нет — and that's perfectly correct too. But in everyday speech people lean on и́ли and let the ли go.

Now look at the word order, because this is the real tell:

• We say Хо́чешь ты э́того и́ли нет — not Ты хо́чешь э́того и́ли нет.

The verb still jumps to the front, exactly where ли used to stand. The ли is gone, but the shape of the question stayed behind — and that inverted word order is your clue that this is a yes/no question in disguise.

A couple more you'll hear all the time:

• Нра́вится тебе́ э́то и́ли нет — Whether you like it or not
• Пра́вда э́то и́ли нет — Whether it's true or not

And when it compresses all the way down, even и́ли can vanish:

• Хо́чешь не хо́чешь, идём. — Like it or not, we're going. (A fixed idiom — learn it as one whole phrase.)

Both versions — with ли and without — are correct. The shorter one just sounds more natural.

«Ли» for doubt and "should I…?"

Russians also reach for ли when they're thinking out loud, weighing something, or hesitating. It's the sound of a person quietly wondering:

• Сто́ит ли е́хать? — Is it worth going?
• Ну́жно ли э́то де́лать? — Do I really need to do this?
• Пра́вильно ли я по́нял? — Did I understand correctly?

If you ever catch yourself unsure and slightly debating with yourself — that's a perfect moment for ли.

A polite way to ask someone: «Можешь ли ты…?»

There's a lovely soft formula that uses ли:

• Мо́жешь ли ты + [verb]…? — Could you…?

It sounds gentle and considerate — a little softer than a plain мо́жешь?:

• Мо́жешь ли ты показа́ть мне го́род? — Could you show me the city?
• Мо́жешь ли ты написа́ть мне? — Could you write to me?
• Мо́жешь ли ты помо́чь ему́? — Could you help him?

Ready-made phrases with «ли»

Some of the most common ли expressions you'll simply learn as whole pieces — no analysis needed:

• вряд ли — unlikely, I doubt it (learn this one first — you'll hear it constantly)
• едва́ ли — hardly, unlikely
• ма́ло ли — you never know, who knows → Ма́ло ли что мо́жет случи́ться. — Who knows what might happen.
• чуть ли не — almost, nearly → Мы жда́ли чуть ли не час. — We waited for almost an hour.
• то ли… то ли… — either… or… (hard to tell which) → То ли дождь, то ли снег. — Either rain or snow, hard to tell.
• не пра́вда ли? — isn't it? / right?

Drop вряд ли into a conversation once, and you'll instantly sound more natural.

Frequently asked questions

What does «ли» mean in Russian? Ли is a small question particle. It turns a statement into a yes/no question, and in reported speech it means whether or if.

Where do you put «ли» in a sentence? Right after the word you're asking about. Ли can never start a sentence — it always attaches to the word in front of it.

Can «ли» go after an adjective? Yes — Краси́вый ли он? (Is he handsome?). Whatever word you're asking about comes first and ли follows, even when it's an adjective, мо́жно, or есть — not only a verb.

What's the difference between «ли» and «если»? Е́сли means if in the sense of a real condition (if it rains…). Ли means if / whether inside a hidden yes/no question (I don't know whether…). If you can swap "if" for "whether" in English, you need ли.

Is «ли» formal? Not really. Ли is natural, everyday Russian and native speakers use it all the time. It just sounds a little more deliberate and makes a yes/no question very clear.

How do you say "whether" in Russian? With ли. For example: Я не зна́ю, придёт ли он. — I don't know whether he will come.

So, is «ли» scary? Вряд ли. 🙂

One last look

Let's gather it all in one breath. Ли does a few jobs: it turns statements into clear yes/no questions, it means whether in reported questions, it helps you wonder out loud, and it lives inside a handful of everyday phrases. And wherever it goes, it always points at the word right in front of it.

You don't have to master every use today. Start by noticing ли when you read and listen — see which word it's standing behind. Pretty soon it won't look mysterious at all. It'll just look like Russian.
