Tento pocit je špatný.

Both tento and ten can mean this/that depending on context, but they are not used in exactly the same way.

• tento is the more explicit word for this
• ten is very common in everyday Czech and can mean that, but also often the/that one/this one depending on context

So Tento pocit je špatný. is a clear, careful way to say This feeling is bad.

In normal conversation, many speakers would also say:

• Ten pocit je špatný.

That is often more natural in everyday speech, but tento is perfectly correct and useful to know.

Pocit is in the nominative singular.

Why? Because it is the subject of the sentence:

• Tento pocit = the thing being talked about
• je špatný = is bad

In Czech, the subject of a sentence is normally in the nominative.

So:

• tento pocit = nominative singular masculine

Because špatný has to agree with pocit.

The noun pocit is:

• masculine
• singular
• nominative

So the adjective must match that, which gives:

• špatný

Compare:

• ten pocit je špatný → masculine singular
• ta myšlenka je špatná → feminine singular
• to rozhodnutí je špatné → neuter singular
• ty pocity jsou špatné → plural

This is called adjective agreement.

Yes, pocit is a masculine noun.

One clue is its dictionary form: nouns ending in a consonant are often masculine in Czech, and pocit ends in -t.

Also, you can see it from agreement:

• tento pocit
• špatný

Both tento and špatný are in masculine singular form, so they show you the gender of pocit.

More specifically, pocit is masculine inanimate.

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

So:

• já jsem = I am
• ty jsi = you are
• on/ona/ono je = he/she/it is

In Tento pocit je špatný, je means is.

In standard Czech, you normally do not omit je in a sentence like this. So:

• Tento pocit je špatný. = correct
• Tento pocit špatný. = not standard Czech

Unlike in some other Slavic languages, Czech usually keeps the present-tense form of to be.

The neutral, most natural order is:

• Tento pocit je špatný.

That is a normal subject + verb + complement pattern.

But Czech word order is more flexible than English, so other orders are possible for emphasis, contrast, or style, for example:

• Špatný je tento pocit.
• Tento pocit špatný je.

These are not the most neutral versions, but they can appear in special contexts.

For learners, the safest pattern is:

• subject + být + adjective

So stick with Tento pocit je špatný.

Not exactly the same.

• Tento pocit je špatný. = This feeling is bad.
• To je špatný pocit. = That/It is a bad feeling.

The difference is where the adjective goes:

• je špatný = is bad → predicate adjective
• špatný pocit = a bad feeling → adjective directly modifying the noun

So the meaning is close, but the sentence structure is different.

Because Czech has no articles.

English distinguishes:

• a feeling
• the feeling
• this feeling

Czech does not use separate words like a or the. Instead, meaning comes from:

• context
• word order
• demonstratives like ten or tento

So:

• pocit can mean a feeling or the feeling, depending on context
• tento pocit clearly means this feeling

A simple pronunciation guide is:

• Tento ≈ TEN-to
• pocit ≈ PO-tsit
• je ≈ ye
• špatný ≈ SHPAT-nee

A few useful notes:

• Czech stress is usually on the first syllable of each word
• š sounds like sh
• c in pocit sounds like ts
• ý is a long vowel, pronounced like a longer ee

So the rhythm is roughly:

TEN-to PO-tsit ye SHPAT-nee

In this sentence, špatný is the normal choice for bad.

• špatný = bad, wrong, poor, unpleasant
• zlý = evil, mean, nasty, bad-tempered

So for a feeling, špatný pocit or pocit je špatný sounds natural.

Using zlý here would usually sound odd unless you meant something more like malicious or evil, which does not fit well with pocit in most contexts.

To make it negative, put není instead of je:

• Tento pocit není špatný. = This feeling is not bad.

To make it a yes/no question, you can use intonation in speech, or a question mark in writing:

• Tento pocit je špatný? = Is this feeling bad?

You can also ask more explicitly:

• Je tento pocit špatný?

That is very clear and common.

So the key forms are:

• je = is
• není = is not
• Je tento pocit špatný? = Is this feeling bad?

Yes, tento is a declined word, so its form changes depending on gender, number, and case.

Here it is:

• tento pocit = nominative masculine singular

Some other forms you may see are:

• tohoto pocitu = genitive
• tomuto pocitu = dative
• tento pocit = accusative (for masculine inanimate, same as nominative)
• o tomto pocitu = locative
• tímto pocitem = instrumental

So tento is not one fixed form. It changes to match the noun and the case.

That is why learning whole phrases is helpful:

• tento pocit
• o tomto pocitu
• s tímto pocitem
