Tento tvar je zajímavý.

Both tento and ten can mean this, but tento is more explicit or emphatic.

• tento tvar = this shape/form
• ten tvar can also sometimes mean that shape/form, depending on context

In modern everyday Czech, people often use tenhle / tenhleten or just ten in speech, but tento is very common in writing and in careful, neutral style.

So Tento tvar je zajímavý. sounds perfectly natural, especially in written or explanatory language.

Tvar is masculine inanimate.

That matters because Czech adjectives and demonstratives must agree with the noun in:

• gender
• number
• case

Here, the noun is singular masculine inanimate, nominative, so the other words match it:

• tento = masculine singular nominative
• zajímavý = masculine singular nominative

You often just have to learn a noun’s gender together with the word. In this sentence, agreement helps confirm it.

Because it agrees with tvar.

In the nominative singular, adjective endings depend on gender:

• masculine animate: often -ý / -í
• masculine inanimate: often -ý / -í
• feminine: -á
• neuter: -é

Since tvar is masculine singular, the adjective appears as zajímavý.

Compare:

• Tento tvar je zajímavý.
• Tato kniha je zajímavá.
• Toto město je zajímavé.

So the ending changes to match the noun.

The sentence uses the nominative case for both tento tvar and zajímavý.

Why?

Because this is a basic X is Y sentence:

• tento tvar = the subject
• je zajímavý = predicate with the verb být (to be)

In Czech, the subject is in the nominative, and the adjective after být is also usually in the nominative.

So:

• tento → nominative singular masculine
• tvar → nominative singular
• zajímavý → nominative singular masculine

Je is the 3rd person singular of být (to be), meaning is.

• Tento tvar je zajímavý. = This shape/form is interesting.

In present-tense Czech, the verb být is normally not omitted in standard sentences like this. So unlike in some languages, you usually need it.

Correct:

• Tento tvar je zajímavý.

Not standard:

• Tento tvar zajímavý.

So yes, je is required here.

Because Czech does not need a separate dummy subject like English sometimes does.

In English, you might say:

• This shape is interesting.

In Czech, the subject is already Tento tvar, so no extra pronoun is needed.

Also, Czech often drops personal pronouns when they are not necessary, because the verb form already gives information. In this sentence, though, there is no missing pronoun at all—the full subject is simply Tento tvar.

Yes. Czech word order is more flexible than English word order, although the basic version here is the most neutral:

• Tento tvar je zajímavý.

Other orders are possible, but they change emphasis:

• Zajímavý je tento tvar. = It is this shape that is interesting.
• Je tento tvar zajímavý? = Is this shape interesting?

So the standard declarative order is best for learners, but Czech can move words around for focus, contrast, or style.

A rough pronunciation guide:

• Tento ≈ TEN-to
• tvar ≈ tvar (with a clear rolled or tapped r)
• je ≈ ye
• zajímavý ≈ za-YEE-ma-vee

A few tips:

• Czech stress is usually on the first syllable of each word:
  • TEN-to
  • tvar
  • ye
  • ZA-jí-ma-vý
• j is pronounced like English y in yes
• á is a long vowel
• ý is also a long vowel

So zajímavý has long vowels in the last two syllables.

It depends on context. Tvar is a broad word and can mean:

• shape
• form
• sometimes outline or configuration

In a sentence like this, the most natural English choice is often shape or form.

For example:

• in geometry or design: shape
• in grammar or linguistics: sometimes form
• in art or technical description: form

So the Czech word is flexible, and the best translation depends on what kind of tvar is being discussed.

Yes, but with a small nuance.

Tento is fully normal and correct, but in casual speech many speakers often prefer:

• tenhle
• sometimes just ten, if the context is clear

So in conversation, you may hear:

• Tenhle tvar je zajímavý.

But Tento tvar je zajímavý. still sounds natural—just a bit more neutral, careful, or written.

Yes, but the meaning can shift depending on context.

• Tento tvar clearly means this shape/form
• Ten tvar can mean that shape/form, or sometimes the shape we’re talking about

So if you specifically want this, tento is safer and clearer for learners.

In real usage, context often decides whether ten means this or that, which can be confusing at first. That is one reason textbooks often use tento when they want to be unambiguous.
