Ой, кран снова течёт.

Ой is an interjection, like oh!, oops!, or uh-oh! in English.

In this sentence, it shows an emotional reaction: annoyance, surprise, or concern because the tap is leaking again.

A few rough English equivalents depending on tone:

• Oh no, the tap is leaking again.
• Oops, the tap is leaking again.
• Uh-oh, the tap is leaking again.

It is very common in everyday speech.

Because ой is an interjection, and in Russian interjections are often separated by a comma from the rest of the sentence.

So:

• Ой, кран снова течёт.

This is similar to English punctuation in something like:

• Oh, the tap is leaking again.

In fast, informal writing, punctuation may sometimes be looser, but the comma here is standard.

Кран here means tap or faucet.

Be careful: кран can also mean crane in other contexts, such as a construction crane. Russian often uses the same word for several related things, and the context tells you which meaning is intended.

In this sentence, because of течёт (is leaking / is running), the meaning is clearly tap/faucet.

Because кран is the subject of the sentence.

In кран снова течёт, the tap is the thing doing the action, so Russian uses the nominative case:

• кран = the tap

If it were an object, the form might change depending on the sentence, but here it stays in the dictionary form.

Снова means again.

So:

• кран снова течёт = the tap is leaking again

Its position is quite natural here: it goes before the verb and modifies the whole action.

You can also hear slightly different word orders, for example:

• Кран опять течёт.
• Снова кран течёт.

But кран снова течёт is a very normal, neutral way to say it.

Both can mean again.

In many everyday situations, they are interchangeable:

• Кран снова течёт.
• Кран опять течёт.

However, there can be a slight nuance:

• снова often sounds a bit more neutral: again
• опять often sounds a bit more emotional or annoyed: again / yet again

So if you are frustrated that the tap is leaking yet another time, опять may sound especially natural. But снова is completely correct here too.

Течёт is the 3rd person singular form of the verb течь.

That means:

• течь = to flow / to run / to leak
• течёт = flows / runs / leaks / is leaking

It looks irregular because течь is not conjugated in a simple predictable way like many beginner verbs.

Some forms are:

• я теку = I flow / I am flowing
• ты течёшь
• он / она / оно течёт
• они текут

So кран течёт literally means the tap flows, but in natural English the best translation is usually the tap is leaking.

Because Russian uses течь for liquids moving where they are coming out.

So it can describe:

• a river flowing
• water running
• a roof leaking
• a tap leaking

With кран, the natural idea is that water is coming out unintentionally or continuously, so English usually says the tap is leaking.

This is one of those places where Russian uses a broader verb and English chooses a more specific one depending on context.

Течёт is pronounced roughly like tee-CHYOT.

Important points:

• ё is pronounced yo
• ё is almost always stressed
• so the stress is on the last syllable: течёт

A rough pronunciation guide:

• течёт ≈ tyi-CHOT / tee-CHYOT
  depending on how detailed you want to be with Russian vowel reduction

Also note that in many printed texts, Russians often write е instead of ё, so you may sometimes see:

• течет

But it is still pronounced течёт.

Because Russian does not normally use a present-tense verb to be the way English does.

English says:

• The tap is leaking.

Russian simply says:

• Кран течёт.

The verb течёт already carries the present-tense meaning, so no separate word for is is needed.

This is very normal in Russian.

Yes, you could, and it would still be understandable.

But:

• Кран снова течёт sounds more neutral and natural in most situations.
• Кран течёт снова may sound a little more marked, as if you are emphasizing again at the end.

Russian word order is flexible, but not random. Different orders can shift emphasis.

A learner should probably use:

• Кран снова течёт.

That is the safest and most natural choice.

It is everyday, neutral-to-informal speech.

The sentence feels very natural in conversation:

• Ой, кран снова течёт.

What makes it conversational is mostly:

• the interjection ой
• the simple, direct wording

Without ой, it becomes more neutral and factual:

• Кран снова течёт.

In this sentence, yes, that is the intended meaning.

But in Russian, кран can refer to several kinds of valves or taps, depending on context, such as:

• a water tap
• a gas tap
• sometimes other kinds of valves

So the core idea is something like a tap/valve. In a household sentence like this one, English usually translates it as tap or faucet.

Because Russian has no articles like a and the.

So:

• кран can mean a tap or the tap

You understand which one is meant from the context. In this sentence, English naturally uses the tap, because the speaker is probably talking about a specific familiar tap in the home:

• Oh, the tap is leaking again.

This is a very common difference between English and Russian.
