Вышивка находится под антибликовым стеклом.

Находится means is located / is situated / is found. It makes the sentence sound a bit more explicit and slightly more formal or descriptive.

So:

• Вышивка находится под антибликовым стеклом = The embroidery is located under anti-reflective glass
• Вышивка под антибликовым стеклом = The embroidery is under anti-reflective glass

The shorter version is also natural, especially in conversation.
The version with находится focuses more clearly on location.

Because the preposition под requires the instrumental case when it means under in the sense of location.

Here the embroidery is already in a location, not moving there, so Russian uses:

• под + instrumental

That is why:

• стекло → стеклом

Compare:

• под стеклом = under the glass / behind the glass
• под столом = under the table
• под мостом = under the bridge

Adjectives in Russian must agree with the noun they describe in gender, number, and case.

The noun here is стеклом, which is:

• singular
• neuter
• instrumental

So the adjective must also be singular, neuter, instrumental:

• антибликовый → dictionary form
• антибликовым → instrumental singular form

So:

• антибликовое стекло = anti-reflective glass in the nominative
• под антибликовым стеклом = under anti-reflective glass after под

Yes, but in a way that matches how English also talks about framed or protected objects.

In Russian, под стеклом is a very normal way to say something is under glass, meaning it is covered or protected by glass. In English, depending on context, you might translate it as:

• under glass
• behind glass
• beneath the glass

So под is literally under, but in this kind of context it often corresponds to natural English behind glass or under glass.

Вышивка means embroidery.

Depending on context, it can refer to:

• the craft itself: embroidery
• a finished embroidered piece: an embroidery / an embroidered work

In this sentence, it most likely means a specific object, such as an embroidered picture or decorative piece.

Also note:

• вышивка is feminine
• that is why the verb is in the 3rd person singular form, which works for any singular subject in the present tense

In Russian, the verb to be is usually not expressed in the present tense.

So Russian often says:

• Он дома = He is at home
• Книга на столе = The book is on the table

In your sentence, Russian does use a verb, but it is not the plain verb to be. It uses находится, which specifically means is located.

So Russian is not skipping is by accident. It is simply using a different structure that is natural in Russian.

Yes. Под can take either the instrumental or the accusative, depending on meaning.

1. Instrumental = location

   • Вышивка находится под стеклом
   • The embroidery is under the glass

2. Accusative = motion toward a position under something

   • Я положил вышивку под стекло
   • I put the embroidery under the glass

So:

• под стеклом = already there
• под стекло = movement to that place

This is a very common Russian pattern.

Yes. Russian word order is flexible.

The given sentence:

• Вышивка находится под антибликовым стеклом

is a neutral, natural order: topic first, then the information about where it is.

You could also say:

• Под антибликовым стеклом находится вышивка

This sounds a bit more like Under the anti-reflective glass is the embroidery, with stronger focus on the location.

So the original order is probably the most straightforward and neutral.

It can often be translated either way, depending on context.

The word блик means glare, reflection, or light flare.
So антибликовый describes something designed to reduce those reflections.

Possible translations:

• anti-glare glass
• anti-reflective glass
• non-reflective glass

In museum, framing, or display contexts, all of these may be reasonable. The exact best translation depends on what kind of glass is meant.

Yes, but it would slightly change the meaning.

• находится = neutral location, is located
• лежит = is lying, which suggests physical position

So:

• Вышивка находится под антибликовым стеклом = neutral statement of location
• Вышивка лежит под антибликовым стеклом = the embroidery is lying under the glass

If the embroidery is in a frame or on display, находится is usually safer and more neutral.

The main stresses are:

• вышИвка
• нахОдится
• под
• антиблИковым
• стеклОм

A rough pronunciation guide:

• vy-SHEEV-ka na-KHO-dit-sya pod an-ti-BLEE-ka-vym ste-KLOM

Stress is very important in Russian, so it is useful to learn the words together with their stressed syllables.
