Salon optyczny jest tutaj.

Literally:

• salon = a salon, shop, or service establishment
• optyczny = optical / optician-related

So salon optyczny is literally optical salon/shop, and in natural English this is usually optician's or optical store.

A useful note: Polish salon does not only mean living room. In many contexts, it also means a business premises, like salon fryzjerski (hair salon).

Because optyczny is an adjective that must agree with salon in:

• gender
• number
• case

Here, salon is:

• masculine
• singular
• nominative

So the adjective also takes the masculine singular nominative form:

• salon optyczny

If the noun changed, the adjective would change too. For example:

• apteka optyczna = optical pharmacy/store-type expression with a feminine noun
• sklepy optyczne = optical shops

Jest means is. It is the 3rd person singular form of być (to be).

So:

• Salon optyczny = the optical shop / optician's
• jest = is
• tutaj = here

Together: Salon optyczny jest tutaj. = The optician's is here.

Usually no, not in a normal present-tense sentence like this.

Polish sometimes omits forms of to be in very informal or headline-like language, but in a standard sentence you should keep jest:

• Salon optyczny jest tutaj.

Without jest, it would sound incomplete or unnatural in most ordinary contexts.

Polish does not have articles like a or the.

So salon optyczny can mean:

• an optical shop
• the optical shop
• sometimes just optical shop

The exact meaning depends on context. In this sentence, English would usually translate it as The optician's is here or There is an optical shop here, depending on context.

Yes, depending on context, but it is not the most literal translation.

The literal structure is:

• Salon optyczny jest tutaj. = The optical shop is here.

But in real life, if someone is asking what is located in a place, English might naturally say:

• There is an optical shop here.

A more directly Polish way to say There is an optical shop here would often be:

• Tutaj jest salon optyczny.
• Jest tutaj salon optyczny.

So the same Polish words can sometimes be understood in a more existential way, depending on emphasis and situation.

The word order can change.

All of these are possible:

• Salon optyczny jest tutaj.
• Tutaj jest salon optyczny.
• Jest tutaj salon optyczny.

The basic meaning stays similar, but the emphasis changes:

• Salon optyczny jest tutaj. → emphasis on the optical shop
• Tutaj jest salon optyczny. → emphasis on here
• Jest tutaj salon optyczny. → often sounds like there is an optical shop here

Polish word order is more flexible than English, but that does not mean it is random. Different orders sound more natural in different contexts.

It is in the nominative case.

Why?

Because salon optyczny is the subject of the sentence:

• Salon optyczny = the thing being talked about
• jest = is
• tutaj = here

The subject of a basic sentence is normally in the nominative in Polish.

Tutaj means here.

It is very close in meaning to tu, which also means here.

• tu = shorter, very common
• tutaj = slightly fuller form, also very common

So you could also say:

• Salon optyczny jest tu.

Both are correct. In many situations, they are interchangeable.

A rough pronunciation guide for an English speaker:

• salon → SA-lon
• optyczny → roughly op-TICH-nih
• jest → roughly yest
• tutaj → roughly TOO-tie

A few helpful sound notes:

• j in Polish sounds like English y in yes
• cz sounds like ch in chop, but usually a bit harder
• y is a vowel that does not exist exactly in English; it is not the same as ee
• Polish stress is usually on the second-to-last syllable

So the stress pattern is approximately:

• SA-lon op-TYCZ-ny jest TU-taj

It can be.

An English speaker may think only of hair salon or sometimes an old-fashioned sitting room sense. In Polish, salon has a wider use and often refers to a commercial place or showroom, for example:

• salon samochodowy = car showroom / dealership
• salon fryzjerski = hair salon
• salon optyczny = optical shop / optician's

So in this sentence, salon definitely refers to a business, not a room in a house.

Yes, it is perfectly possible, especially if someone is pointing out a place on a map, in a building, or on a street.

For example:

• Someone asks where the optician's is.
• You point and say: Salon optyczny jest tutaj.

That said, in very natural everyday Polish, people might also say:

• Tu jest salon optyczny.
• Tutaj jest optyk.

The second version uses optyk, which can mean optician and sometimes, by extension in context, the optician's shop.
