Tento pokoj je příjemný.

Word by word:

• Tento = this
• pokoj = room
• je = is
• příjemný = pleasant / nice / comfortable / agreeable

So the structure is very close to English: This room is pleasant.

Because tento has to agree with pokoj.

In Czech, words like this change form depending on:

• gender
• number
• case

pokoj is:

• masculine inanimate
• singular
• nominative here, because it is the subject

So the correct form is tento.

A few related forms are:

• ten = that / the basic demonstrative form
• tento = this, masculine singular nominative
• tato = this, feminine singular nominative
• toto = this, neuter singular nominative

So:

• Tento pokoj = this room
• Tato místnost = this room if you use the feminine noun místnost
• Toto město = this city

Because the adjective must agree with pokoj too.

Since pokoj is:

• masculine inanimate
• singular
• nominative

the adjective also takes the masculine singular nominative form:

• příjemný

Compare:

• Tento pokoj je příjemný. = masculine
• Tato místnost je příjemná. = feminine
• Toto místo je příjemné. = neuter

So the -ý ending tells you the adjective matches a masculine noun like pokoj.

Pokoj is a masculine inanimate noun.

That matters because Czech grammar depends heavily on noun gender. Gender affects:

• demonstratives like tento
• adjectives like příjemný
• sometimes numeral forms
• case endings

So in this sentence, both tento and příjemný are shaped by the fact that pokoj is masculine singular nominative.

In standard Czech, yes, je is necessary in this sentence.

So you say:

• Tento pokoj je příjemný.

Not normally:

• Tento pokoj příjemný.

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

A rough English-friendly guide is:

TEN-toh PO-koy yeh PRZHEE-yehm-nee

A few important notes:

• j in Czech sounds like English y
  • so je sounds like ye
• oj in pokoj sounds roughly like oy
• ř in příjemný is a special Czech sound with no exact English equivalent
• í is a long vowel, so pří- is longer than a short i
• ý is also a long vowel

A more careful breakdown:

• Tento = TEN-to
• pokoj = PO-koy
• je = ye
• příjemný ≈ přee-yem-nee, with the Czech ř sound at the start

If ř is difficult, that is completely normal for learners.

Příjemný often means:

• pleasant
• nice
• agreeable
• comfortable

For a room, it can suggest that the room feels nice, comfortable, welcoming, or generally good to be in.

Depending on context, English translations could be:

• This room is pleasant.
• This room is nice.
• This room is comfortable.

So pleasant is correct, but not the only possible translation.

Yes, but the meaning shifts a little.

• Tento pokoj = this room
• Ten pokoj = usually that room, though in some contexts Czech ten can also work a bit like a more neutral the/that

If you specifically mean this room, tento pokoj is the clearest choice.

So:

• Tento pokoj je příjemný. = This room is pleasant.
• Ten pokoj je příjemný. = more like That room is pleasant.

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

• Tento pokoj je příjemný.

Other versions are possible, for example:

• Pokoj je příjemný. = The room is pleasant / This room is pleasant depending on context
• Příjemný je tento pokoj. = marked emphasis, something like It is this room that is pleasant
• Tento pokoj je opravdu příjemný. = This room is really pleasant

Czech word order often changes emphasis rather than basic meaning.

Because Czech does not have articles like English a/an and the.

So pokoj can mean:

• a room
• the room
• just room

The exact meaning depends on context.

In this sentence, tento already makes it specific:

• Tento pokoj = this room

So there is no need for an article.

It can mean more than one thing.

Most commonly:

• pokoj = room

But in other contexts, pokoj can also mean:

• peace
• calm

In Tento pokoj je příjemný, it clearly means room.

This is a normal kind of vocabulary overlap in Czech, and the context usually makes the meaning obvious.

You can say:

• Tento pokoj je velmi příjemný.

Here:

• velmi = very

So the sentence becomes:

• Tento pokoj je velmi příjemný. = This room is very pleasant.

You could also hear:

• Tento pokoj je moc příjemný.

But velmi is the more standard neutral choice.
