Швейная машина уже готова.

In the present tense, Russian usually omits the verb "to be".

So:

• Швейная машина уже готова. literally: Sewing machine already ready.

But it means:

• The sewing machine is already ready.

This is completely normal in Russian. Compare:

• Он дома. = He is at home.
• Она занята. = She is busy.

In past and future tenses, forms of быть do appear:

• Швейная машина была готова. = The sewing machine was ready.
• Швейная машина будет готова. = The sewing machine will be ready.

This is a very common question. Готова is the short form of the adjective готовый.

Russian often uses:

• the full form when the adjective directly describes a noun
• the short form when the adjective is the predicate, meaning is ready

So:

• готовая машина = a ready machine / a machine that is ready
• машина готова = the machine is ready

In your sentence, готова is the natural choice because it is the main predicate of the sentence.

A rough pattern:

• Полная форма: describes a noun
• Краткая форма: says what something is like right now

Because машина is a feminine noun.

In Russian, adjectives agree with the noun in gender, number, and case.

Here:

• машина = feminine singular
• швейная must match it
• готова must also match it

So you get:

• швейная машина
• машина готова

Compare with other genders:

• Стол уже готов. = The table is already ready.
  masculine
• Письмо уже готово. = The letter is already ready.
  neuter
• Документы уже готовы. = The documents are already ready.
  plural

Уже usually means already.

So:

• Швейная машина уже готова. = The sewing machine is already ready.

It often suggests that the result has been achieved by now, perhaps sooner than expected or after some waiting.

Compare:

• Машина готова. = The machine is ready.
• Машина уже готова. = The machine is already ready.

So уже adds the idea of by this point.

Russian word order is more flexible than English, but this position is very natural.

• Швейная машина уже готова.

Here, уже comes before готова, which is common because it modifies the idea of being ready already.

Other orders are possible, but they can change emphasis:

• Уже швейная машина готова. — unusual without special context
• Швейная машина готова уже. — possible, but more marked or conversational

For a learner, subject + уже + predicate is a good default pattern here.

It is in the nominative case, because it is the subject of the sentence.

You can tell from the endings:

• машина = nominative singular feminine
• швейная agrees with it in nominative singular feminine

So the structure is:

• Швейная машина = subject
• уже готова = predicate

If the noun were in another case, the adjective would also change. For example:

• Я вижу швейную машину. = I see the sewing machine.
  Here it is accusative: швейную машину

Швейная comes from the idea of sewing.

The phrase:

• швейная машина

literally means:

• sewing machine

The adjective швейный / швейная / швейное means something like related to sewing.

It is built from the same general word family as verbs like шить (to sew).

So this is a standard Russian way to say sewing machine.

The stress is:

• шве́йная маши́на уже́ гото́ва

A rough English-friendly pronunciation might be:

• SHVAY-na-ya ma-SHEE-na oo-ZHÉ ga-ta-VA

A few notes:

• шв at the beginning of швейная can feel difficult; say shv
• ж in уже sounds like the s in measure
• unstressed о in готова sounds closer to a, so it sounds more like gataVA

Normally, no—not in this context.

If you want to say The sewing machine is ready, you should say:

• Швейная машина готова.

Using готовая at the end would sound wrong or very unnatural in standard Russian, because the predicate here calls for the short form.

Use:

• готовая before a noun: готовая швейная машина
• готова as the predicate: швейная машина готова

It can sometimes feel like ready, finished, or prepared, depending on context.

For example, this sentence could mean the sewing machine is:

• ready to use
• ready after being repaired
• ready after setup or preparation

So готова is broader than just one English word. The exact nuance depends on the situation.

Yes, if the context already makes it clear which machine you mean.

• Машина уже готова. = The machine is already ready.

But be careful: машина often also means car, not just machine.

So if you specifically mean a sewing machine, saying швейная машина avoids ambiguity.

In context, though, Russians often shorten phrases once the topic is already known.
