Tato služba tady neexistuje.

Because služba is a feminine noun and here it is the subject of the sentence, so it must be in the nominative singular.

• služba = a service
• nominative singular of služba = služba
• the feminine singular nominative form of this is tato

So:

• tato služba = this service

Compare:

• tento = masculine singular nominative
• tato = feminine singular nominative
• toto = neuter singular nominative

And službu would be accusative singular, which would be used if service were the direct object, not the subject.

Yes. Tato is the feminine singular nominative form of the demonstrative pronoun/determiner meaning this.

In Czech, this changes form depending on the gender and case of the noun:

• tento dům = this house
• tato služba = this service
• toto město = this city

So tato is not a standalone random word—it agrees with služba in gender, number, and case.

Because the subject, tato služba, is singular.

• služba = singular
• therefore the verb must also be singular: existuje / neexistuje

If the subject were plural, the verb would change:

• Tato služba neexistuje. = This service does not exist.
• Tyto služby neexistují. = These services do not exist.

Neexistuje = does not exist

It consists of:

• existuje = exists
• ne- = the negative prefix, giving does not / not

So:

• existuje = it exists
• neexistuje = it does not exist

This is very common in Czech: negation is often made by adding ne- directly to the verb.

Examples:

• je = is → není = is not
• má = has → nemá = does not have
• existuje = exists → neexistuje = does not exist

Because Czech verbs usually already contain the subject information, and when the subject is explicitly stated, you normally do not need an extra pronoun like it.

In English, you say:

• This service does not exist.

In Czech, the subject tato služba is already there, so the verb simply agrees with it:

• Tato služba tady neexistuje.

Czech often omits subject pronouns unless they are needed for emphasis or clarity.

Tady means here.

So the sentence is literally:

• Tato služba tady neexistuje.
• This service does not exist here.

It adds a location-based limitation: the service may exist somewhere else, but not here.

Without tady, the sentence becomes more general:

• Tato služba neexistuje. = This service does not exist.

With tady, it means:

• This service doesn’t exist here / isn’t available here.

They are very close in meaning:

• tady = here
• zde = here

But the difference is mainly in style:

• tady sounds more everyday and conversational
• zde sounds more formal, written, or official

So:

• Tato služba tady neexistuje. = natural, everyday
• Tato služba zde neexistuje. = more formal or official

Both are grammatically correct.

Yes, Czech word order is more flexible than English, because grammatical endings carry a lot of information. But different word orders can change the emphasis.

The neutral, natural order here is:

• Tato služba tady neexistuje.

Other possible orders include:

• Tady tato služba neexistuje.
  Emphasis on here
• Neexistuje tady tato služba.
  More marked; could sound more rhetorical or contrastive

Even though the order can change, the most natural version for a simple statement is the original one.

Yes. Tahle služba is a common colloquial alternative to tato služba.

Both mean this service, but:

• tato služba = standard, neutral, a bit more formal/written
• tahle služba = more conversational/spoken

So in everyday speech, you may hear:

• Tahle služba tady neexistuje.

That sounds very natural in spoken Czech.

Neexistuje is correct and direct, but in real life Czech might also use other phrases depending on the context.

For example:

• Tato služba tady neexistuje. = This service does not exist here.
• Tato služba tady není. = This service is not here / is unavailable here.
• Tuto službu tady nenabízíme. = We do not offer this service here.

So neexistuje sounds quite literal: the service does not exist in this place/system/context. In practical situations, a speaker might prefer a phrase like není or nenabízíme, depending on what exactly they mean.

Approximate pronunciation:

• služba ≈ SLOOZH-ba

A bit more carefully:

• slu- like sloo
• ž sounds like the s in measure or vision
• ba like bah

So the middle sound is not an English z or j, but ž /ʒ/.

The full sentence is approximately:

• Tato služba tady neexistuje.
• TA-to SLOOZH-ba TA-dy ne-eg-zis-TOO-ye

That is only an approximation, but it is close enough to help an English speaker get started.
