Раз уж кухня такая тесная, в неё вряд ли поместится большой круглый стол.

Раз уж is a set phrase that means something like since, seeing that, given that, or if that’s the case.

In this sentence, it introduces a reason:

• Раз уж кухня такая тесная... = Since the kitchen is so cramped...

The word уж adds emphasis and often gives a slightly resigned or matter-of-fact tone, as if the speaker is accepting a situation and drawing a conclusion from it.

So the tone is not just logical, but a bit like:

• Well, since the kitchen is this cramped...

Такая goes naturally with an adjective to mean so/such a:

• такая тесная кухня = such a cramped kitchen
• кухня такая тесная = the kitchen is so cramped

This is a very common pattern in Russian.

By contrast, так usually modifies the adjective directly:

• кухня так тесна or кухня так тесная = the kitchen is so cramped

So both такая тесная and так тесная/тесна are possible in principle, but такая тесная sounds very natural and conversational here.

Also, такая agrees with кухня:

• feminine
• singular
• nominative

So:

• такая
• тесная

both match кухня.

Yes, it could be тесна. Russian has two possibilities in predicate position:

• full form: кухня тесная
• short form: кухня тесна

In modern everyday Russian, the full form is often more common and neutral in speech, especially in sentences like this.

So:

• кухня такая тесная sounds very natural and conversational.
• кухня так тесна is also correct, but sounds a bit more literary or formal.

The meaning is basically the same here.

This is a very common and important point.

With в + accusative, Russian often expresses movement into something or the idea of something going into / fitting into something.

With в + prepositional, it expresses location inside something.

Here:

• в неё = into it
• в ней = in it / inside it

The verb поместиться means to fit, and it is understood as fit into a space, so Russian uses:

• в + accusative

That is why we get:

• в неё вряд ли поместится стол = a table will hardly fit into it

not:

• в ней

because в ней would focus on location rather than fitting into the space.

Because Russian third-person pronouns often gain an initial н- after many prepositions.

Compare:

• её = her / it
• у неё = at her / she has
• к ней = to her
• в неё = into her / it

So неё here refers back to кухня.

This is a standard grammar rule:

• without a preposition: её
• after a preposition: often неё

Also, the ё shows the stress:

• неё is pronounced roughly ni-YO

In many texts you may see нее instead of неё, because Russian often omits the dots over ё in ordinary writing.

Вряд ли means hardly, unlikely, or probably not.

In this sentence:

• в неё вряд ли поместится большой круглый стол
• a big round table will hardly / probably won’t fit into it

It is a fixed expression and does not change form.

It often appears before the verb:

• вряд ли поместится

but Russian word order is flexible, so the exact placement can vary depending on emphasis.

A useful way to think of it is:

• вряд ли = it is unlikely that...

So the whole clause could be mentally expanded as:

• Маловероятно, что в неё поместится большой круглый стол.

Поместится is the future tense of the perfective verb поместиться.

Here it means:

• will fit
• will be able to fit in as a whole/result

Perfective is used because the speaker is talking about the result of a single situation: whether the table can fit into the kitchen.

Compare:

• поместится = will fit / will manage to fit
• помещается = fits / is fitting / habitually fits

In this sentence, Russian wants the idea of result:

• if the kitchen is that cramped, the table won’t fit

So поместится is the natural choice.

Because большой круглый стол is the subject of the verb поместится.

The thing that does the fitting, grammatically speaking, is the table:

• стол поместится = the table will fit

The phrase в неё is just a prepositional phrase telling you where it would fit.

So the structure is:

• [big round table] = subject, nominative
• [will fit] = verb
• [into it] = prepositional phrase

That is why you get:

• большой круглый стол

not an oblique case.

This is the most natural neutral order here.

Russian adjective order is more flexible than English, but there are still common tendencies. A broad descriptive adjective like большой often comes before a more specific one like круглый:

• большой круглый стол = a big round table

This sounds natural and unmarked.

You could change the order for emphasis:

• круглый большой стол

but that would sound less neutral in this context.

So learners can safely treat большой круглый стол as the normal way to say a big round table.

Because the sentence begins with a subordinate clause introduced by раз уж:

• Раз уж кухня такая тесная, ...

This first part gives the reason or basis for the conclusion in the main clause.

So the structure is:

• subordinate clause: Раз уж кухня такая тесная
• main clause: в неё вряд ли поместится большой круглый стол

Russian separates these with a comma, just as English often does with a clause like:

• Since the kitchen is so cramped, a big round table probably won’t fit in it.

Not exactly.

Тесный / тесная means cramped, tight, or having too little space. It emphasizes lack of room rather than just physical size.

So:

• маленькая кухня = a small kitchen
• тесная кухня = a cramped kitchen

A kitchen can be small without feeling especially cramped, but тесная strongly suggests that space is inconveniently limited.

That nuance is why it works well with the idea that a big round table won’t fit.

The word order is natural and helps the sentence flow from place to likelihood to thing:

• в неё = into it
• вряд ли = probably not / hardly
• поместится = will fit
• большой круглый стол = a big round table

Russian often places the location early when it is already relevant from the previous clause. Since we were just talking about the kitchen, starting with в неё makes good sense.

A more straightforward version like:

• Большой круглый стол в неё вряд ли поместится

is also possible.

Both are correct; the difference is mainly emphasis and information flow, not basic meaning.
