Новая грамматическая тема: конструкция «не только не ..., но и ...» усиливает отрицание.

Because they do different jobs:

• the first не is part of the fixed expression не только ... но и ... = not only ... but also ...
• the second не negates the word or phrase that follows, often a verb

So in a sentence like:

• Он не только не помог, но и помешал.

the structure is:

• не только = not only
• не помог = did not help
• но и помешал = but also got in the way / hindered

So Russian needs both:

• one for the pattern,
• one for the actual negation inside the first part.

It makes the negative idea stronger.

Compare:

• Он не помог. = He didn’t help.
• Он не только не помог, но и помешал. = Not only did he not help, but he actually hindered.

The construction does more than say something didn’t happen. It often adds:

• surprise,
• contrast,
• disappointment,
• or the idea that the reality was even worse than expected.

So it is often used when the speaker wants to say:

• X did not happen
• and something additional happened, often in the opposite or a more extreme direction.

Yes, that is usually the closest English equivalent.

For example:

• Он не только не извинился, но и рассердился.
• He not only didn’t apologize, but also got angry.

But in Russian this structure can feel especially natural when the second part shows something unexpected, worse, or contrary to what should have happened.

Very often, English might translate it more naturally as:

• Far from apologizing, he got angry instead.
• Not only did he fail to apologize, he actually got angry.

So the core meaning matches English, but the Russian construction is a very standard way to intensify negation.

No. In fact, it is often not negative.

Usually the pattern is:

• first part = negated
• second part = an added fact, often stronger, opposite, or more surprising

Examples:

• Он не только не пришёл, но и не позвонил.
  Not only did he not come, but he also didn’t call.
  → both parts are negative

• Он не только не пришёл, но и забыл о встрече.
  Not only did he not come, but he also forgot about the meeting.
  → first part is negative, second is not grammatically negative

• Она не только не обиделась, но и засмеялась.
  She not only didn’t get offended, but even laughed.
  → second part is positive in form, but adds strong contrast

So the second part can be:

• negative,
• positive,
• opposite in meaning,
• or simply an additional stronger fact.

No. It can be used with different kinds of predicates and descriptions, not just verbs.

For example:

• Он не только не врач, но и вообще не имеет медицинского образования.
  He is not only not a doctor, but he doesn’t even have medical training.

• Она не только не устала, но и была полна энергии.
  She was not only not tired, but full of energy.

• Это не только не сложно, но и очень интересно.
  It is not only not difficult, but also very interesting.

So the pattern can work with:

• verbs,
• adjectives,
• nouns,
• adverbs,
• whole predicate phrases.

The basic pattern is fairly fixed:

• не только не ..., но и ...

In many sentences, только stays right after the first не.

Examples:

• Он не только не помог, но и помешал.
• Она не только не согласилась, но и возмутилась.

What matters is that the reader clearly sees the pair:

• не только ...
• но и ...

Russian word order is somewhat flexible, but for learners it is best to treat this as a set construction and keep it in the standard form.

Because но и introduces the second part of a paired construction, and in practice it is usually separated by a comma.

Example:

• Он не только не ответил, но и не прочитал сообщение.

The comma marks the boundary between:

• the first part: не только не ответил
• the second part: но и не прочитал сообщение

For learners, the safest rule is:

• if you use не только не ..., но и ... to connect two clauses or two clearly separate parts, put a comma before но и.

Yes, but then the meaning is different.

Compare:

• Он не только работает, но и учится.
  He not only works, but also studies.
  → no intensified negation; this is the ordinary не только ..., но и ... pattern

• Он не только не работает, но и не ищет работу.
  He not only does not work, but also is not looking for work.
  → intensified negation in the first part

So:

• не только ..., но и ... = ordinary not only ... but also ...
• не только не ..., но и ... = not only not ... but also ..., with stronger negative force

Not always, but it often carries some emphasis.

It can sound:

• emotionally charged,
• critical,
• surprised,
• ironic,
• or simply strongly contrastive

For example:

• Он не только не выполнил задание, но и потерял документы.
  This sounds stronger and more expressive than just saying he didn’t do the task.

In neutral writing, it is still perfectly acceptable, especially when you want to show:

1. absence of an expected action, and
2. an additional fact that makes the situation clearer or worse.

So it is not necessarily dramatic, but it is definitely emphatic.

Very often, yes.

That is one of the most common uses.

Examples:

• Он не только не поддержал меня, но и раскритиковал.
  He not only didn’t support me, but actually criticized me.

• Она не только не испугалась, но и заинтересовалась.
  She not only wasn’t frightened, but became interested.

In both cases, the speaker suggests:

• one expected outcome did not happen,
• and instead something else happened, often unexpectedly.

This is why the construction feels stronger than a simple negative sentence.

Yes, very often the sense in English is close to but even ... or in fact ....

For example:

• Он не только не извинился, но и обвинил меня.
• Possible translations:
  • He not only didn’t apologize, but also blamed me.
  • He didn’t just fail to apologize—he even blamed me.
  • Far from apologizing, he actually blamed me.

So although Russian uses но и, the overall meaning can sometimes be stronger than a plain English but also. Depending on context, English may naturally use:

• but even
• actually
• instead
• far from

Here are a few very common-looking models:

• Он не только не помог, но и помешал.
  He not only didn’t help, but also got in the way.

• Она не только не согласилась, но и начала спорить.
  She not only didn’t agree, but also started arguing.

• Мы не только не успели, но и забыли документы.
  We not only didn’t make it in time, but also forgot the documents.

• Это не только не дорого, но и очень удобно.
  It’s not only not expensive, but also very convenient.

• Ребёнок не только не испугался, но и рассмеялся.
  The child not only wasn’t scared, but even laughed.

These are good models because they show the main idea clearly:

• expectation is denied in the first part,
• then the second part adds something further.
