Moje dcera už není unavená.

Because dcera (daughter) is a feminine noun, and the possessive my has to agree with the noun’s gender.

For my, the basic singular forms are:

• můj for masculine
• moje / má for feminine
• moje / mé for neuter

So:

• můj syn = my son
• moje dcera or má dcera = my daughter
• moje auto or mé auto = my car

In this sentence, moje dcera is correct because dcera is feminine.

Yes. Má dcera and moje dcera both mean my daughter.

In many situations, má sounds a bit shorter and more natural in everyday speech, while moje can sound slightly more emphasized or just stylistically different. But both are completely correct.

So these are both fine:

• Má dcera už není unavená.
• Moje dcera už není unavená.

Už usually means already or any more / any longer, depending on context.

In this sentence, it works like no longer or not ... anymore:

• Moje dcera už není unavená.
• My daughter is not tired anymore.

So even though už often gets translated as already, with a negative verb it commonly gives the sense of no longer:

• Už nepracuji. = I don’t work anymore.
• Už tam není. = He/She isn’t there anymore.

Yes. Není is the negative form of je (is).

The verb být (to be) has these forms in the present tense:

• jsem = I am
• jsi = you are
• je = he/she/it is
• jsme = we are
• jste = you are / you all are
• jsou = they are

To make them negative, Czech usually adds ne-:

• nejsem = I am not
• nejsi = you are not
• není = he/she/it is not
• nejsme = we are not
• nejste = you are not
• nejsou = they are not

So není here means is not.

Because adjectives in Czech agree with the noun they describe.

Here, unavená describes dcera, and dcera is:

• feminine
• singular
• in the nominative case

So the adjective must also be feminine singular nominative:

• unavený = masculine
• unavená = feminine
• unavené / unavený = neuter or plural, depending on context

Compare:

• Syn je unavený. = The son is tired.
• Dcera je unavená. = The daughter is tired.
• Dítě je unavené. = The child is tired.

There is a word for is: it is inside není.

English uses two words:

• is not

Czech combines that into one form:

• není

So:

• je = is
• není = is not

That is normal for Czech and many other Slavic languages.

Not completely. Czech word order is more flexible than English, but different orders can change the emphasis.

The neutral order here is:

• Moje dcera už není unavená.

You may also hear:

• Moje dcera není už unavená.
• Už moje dcera není unavená.

These alternatives are possible, but the first version sounds the most natural and neutral for most situations.

A good learner rule is:

• keep už before the negative verb phrase unless you have a special reason to emphasize something else.

Yes, if the context makes it clear whose daughter you mean.

• Dcera už není unavená. = The daughter / My daughter is not tired anymore, depending on context.

Czech often leaves out words that are obvious from the situation. But if you want to make it clear that you mean my daughter, keeping moje is helpful.

Yes. Dcera is the subject of the sentence, so it is in the nominative case.

The basic structure is:

• Moje dcera = subject
• už není = verb phrase
• unavená = predicate adjective

Because dcera is the subject, both moje and unavená appear in forms that match feminine singular nominative.

A simple learner-friendly pronunciation guide:

• dcera ≈ d-tse-ra
• není ≈ ne-nee

A few details:

• The c in Czech is pronounced like ts.
• So dc at the start of dcera can feel unusual for English speakers. It is roughly dts.
• The final í in není is a long ee sound.

So the whole sentence is approximately:

• MO-ye DTSE-ra oozh NE-nee oo-na-VE-naa

That is only approximate, but it is a useful starting point.

No. That would be incorrect, because unavený is the masculine form.

Since dcera is feminine, the adjective must also be feminine:

• dcera ... unavená ✅
• dcera ... unavený ❌

If the subject were masculine, then unavený would be correct:

• Můj syn už není unavený. = My son is not tired anymore.
