Можно удлинить рукава после примерки.

In Russian, можно is often used in an impersonal construction. It means something like:

• it is possible to...
• one can...
• you can...

So Можно удлинить рукава literally means It is possible to lengthen the sleeves.

Russian often leaves out a formal subject like English it. English needs it is possible, but Russian can simply say можно.

After можно, Russian usually uses the infinitive:

• Можно сделать — it is possible to do
• Можно изменить — it is possible to change
• Можно удлинить — it is possible to lengthen

So the pattern is:

можно + infinitive

This is very common and natural in Russian.

Удлинить is the perfective form, while удлинять is the imperfective form.

Here, perfective is used because the sentence refers to a complete result: making the sleeves longer as a finished alteration.

• удлинить — to lengthen, to make longer completely / as a completed action
• удлинять — to be lengthening, to lengthen in general, repeatedly, or as a process

With можно, both aspects are possible in some contexts, but here удлинить sounds natural because the speaker means a concrete alteration that can be done.

Рукава is the accusative plural of рукав (sleeve).

The verb удлинить takes a direct object, so рукава is in the accusative:

• рукав — sleeve
• рукава — sleeves

For inanimate masculine plural nouns, the accusative plural is the same as the nominative plural, so it looks like рукава in both cases.

That is why the form is рукава, not something else.

Because the plural of рукав is irregular from an English learner’s point of view.

The correct forms are:

• singular: рукав
• plural: рукава

Many Russian masculine nouns form the plural in -а / -я instead of -ы / -и. This is something you often just have to learn word by word.

So:

• дома — houses
• берега — shores
• рукава — sleeves

Because the preposition после requires the genitive case.

So:

• примерка — fitting, trying on
• после примерки — after the fitting

This is a very important pattern:

после + genitive

Examples:

• после урока — after the lesson
• после работы — after work
• после примерки — after the fitting

Since примерка is feminine and ends in -а, its genitive singular is примерки.

Примерка means a fitting or trying-on session, especially for clothing.

It is commonly used in contexts like:

• tailoring
• dressmaking
• altering clothes
• trying on a garment before final adjustments

So in this sentence, после примерки means after the fitting or after trying it on.

It suggests that once the person has tried the garment on, it is possible to decide whether the sleeves need to be lengthened.

Usually it expresses possibility, though in some contexts можно can also feel like it is allowed.

Here, Можно удлинить рукава после примерки most naturally means:

• It is possible to lengthen the sleeves after the fitting
• The sleeves can be lengthened after trying it on

In a tailoring context, this is more about what can be done technically or practically, not about asking permission.

Russian has no articles like the or a.

So рукава can mean:

• sleeves
• the sleeves
• your sleeves
• the garment’s sleeves

The exact meaning comes from the context.

In this sentence, the context makes it clear that these are the sleeves of the garment being tried on.

Yes. Russian word order is flexible.

The neutral order here is:

Можно удлинить рукава после примерки.

But other orders are possible, for example:

• После примерки можно удлинить рукава.

This version puts more emphasis on after the fitting.

Both are grammatical. The difference is mostly about focus and style, not basic meaning.

Yes, that is the basic idea.

После примерки means after the fitting. It suggests a sequence:

1. first, the garment is tried on
2. then, based on that fitting, the sleeves can be lengthened

This makes practical sense in tailoring, because the fitting helps determine whether the sleeves are too short.

Yes, that is a fairly literal translation.

Possible English renderings include:

• One can lengthen the sleeves after the fitting.
• The sleeves can be lengthened after fitting.
• It is possible to lengthen the sleeves after trying it on.

The most natural English translation depends on context, but grammatically the Russian sentence is straightforwardly saying that sleeve-lengthening is possible after the fitting.

Not necessarily. The sentence is intentionally subjectless.

Russian often uses impersonal sentences when the doer is not important or not specified. Here, the focus is on the fact that the alteration is possible, not on who will do it.

So the sense is not really:

• we can lengthen or
• they can lengthen

but rather:

• it can be done
• it is possible to do it

That makes the sentence sound general and practical, which fits the context well.
