Je tento datový limit tak velký jako jiný?

Because this is a yes/no question. In standard Czech, yes/no questions are very often formed by putting the finite verb first.

So:

Je tento datový limit ... ?

is the normal written pattern, just like English Is this data limit ... ?

Czech does not need a helper like do. In speech, people can sometimes keep normal statement order and use rising intonation, but verb-first is the clearest standard form.

Tento means this. It is a demonstrative.

It is perfectly correct here, but it sounds a bit more neutral/written/formal than everyday spoken forms like tenhle.

So these are roughly comparable:

• tento datový limit = this data limit
• tenhle datový limit = this data limit, more colloquial

A learner should know that tento is very common in writing and careful speech.

Because Czech has no articles.

English needs words like a, an, and the, but Czech usually leaves that information to context or uses words like tento only when it really means this.

So:

• limit can mean a limit, the limit, or just limit, depending on context
• tento limit specifically means this limit

That is one of the big differences between English and Czech.

Datový limit is a noun phrase made of:

• datový = data-related
• limit = limit

So datový limit is the normal Czech way to say something like a data limit, data cap, or data allowance in a phone or internet context.

The adjective datový is formed from data. Czech often uses an adjective where English uses a noun as a modifier.

This is the Czech pattern for as ... as:

tak + adjective + jako

So:

• tak velký jako = as big as

A very common alternative is:

• stejně velký jako

Both are possible. Stejně velký jako often sounds a bit more explicit or natural to learners because it clearly suggests the same size as.

Tento datový limit is in the nominative singular.

Why?

• it is the subject of the sentence
• the verb je means is
• the thing being described is limit

Also, the adjective datový agrees with limit, so it is also nominative singular masculine inanimate.

Since limit is masculine inanimate, the forms are:

• tento
• datový
• velký

all matching that noun.

Because velký agrees with limit.

The noun limit is:

• masculine
• singular
• inanimate
• nominative here

So the adjective also appears in the matching form:

• velký

This is a basic Czech rule: adjectives usually agree with the noun they describe in gender, number, and case.

Yes, in a sense the noun is understood rather than spoken.

Jiný here means something like another one or a different one, with limit omitted because it is already clear from context.

So the full idea is like:

• jako jiný limit
• jako jiný datový limit

Czech does this quite naturally when the repeated noun is obvious.

Still, if there is no clear context, bare jiný can feel a little vague.

It can suggest either, depending on context.

That is normal for jiný. It often covers both ideas:

• different
• another

If you want to be clearer, Czech can use more specific wording, for example:

• jako jiný datový limit = like a different/another data limit
• jako ten druhý = like the other one

If you mean one specific second item, ten druhý is often clearer than just jiný.

It is grammatical and understandable, but it can sound a bit literal or context-light.

Two reasons:

1. jiný by itself is slightly vague unless the context is already clear.
2. With something numerical like a limit, Czech often prefers vysoký rather than velký.

So depending on what you mean, a Czech speaker might more naturally say something like:

• Je tento datový limit stejně vysoký jako ten druhý?
• Je tento datový limit stejně velký jako jiný datový limit?
• Má tento tarif stejný datový limit jako jiný?

So the original sentence is fine for learning grammar, but in real-life usage, a Czech speaker might choose slightly different wording.

It is not wrong, but vysoký is often more idiomatic for limits, especially if you are talking about a numerical cap.

Czech often says:

• vysoký limit = a high limit

rather than:

• velký limit = a big limit

So if the idea is about the amount allowed, many speakers would prefer vysoký. If you are thinking more abstractly about size or extent, velký is still understandable.

Yes, especially in speech, if your intonation clearly makes it a question.

But in standard written Czech, the more typical yes/no question pattern is to put the verb first:

• Je tento datový limit tak velký jako jiný?

So both can exist, but verb-first is the safer choice for learners.
