Ja też nie mam czasu.

Yes — Polish often drops subject pronouns because the verb form already shows who is doing the action.

• mam already means I have
• so Nie mam czasu already means I don’t have time

Adding ja makes the subject more explicit. It often adds one of these effects:

• emphasis: I also don’t have time
• contrast: someone else doesn’t have time, and I don’t either
• clarity in conversation

So:

• Nie mam czasu = neutral, very common
• Ja też nie mam czasu = I don’t have time either / me neither

Też means also, too, or either, depending on the English sentence.

In this sentence:

• Ja też nie mam czasu = I also don’t have time
• in natural English, this is often I don’t have time either

So even though Polish uses też, English may use too, also, or either depending on whether the sentence is positive or negative.

Because mam is the 1st person singular form of mieć = to have.

Present tense of mieć:

• ja mam = I have
• ty masz = you have
• on/ona/ono ma = he/she/it has
• my mamy = we have
• wy macie = you have
• oni/one mają = they have

To make it negative, Polish adds nie before the verb:

• mam = I have
• nie mam = I do not have / I don’t have

This is one of the most important grammar points in the sentence.

The noun czas = time.
After a negated verb like nie mam, the direct object usually changes to the genitive case.

So:

• Mam czas = I have time
• Nie mam czasu = I don’t have time

Here:

• czas = nominative / accusative form
• czasu = genitive form

This happens very often with mieć in negative sentences:

• Mam samochód → Nie mam samochodu
• Mam pieniądze → Nie mam pieniędzy
• Mam czas → Nie mam czasu

Yes, very common.

A classic pattern in Polish is:

• positive sentence: object often in the accusative
• negative sentence: object often changes to the genitive

Examples:

• Mam kota = I have a cat

• Nie mam kota = I don’t have a cat

• Widzę samochód = I see a car
• Nie widzę samochodu = I don’t see a car

So nie mam czasu is following a very standard pattern.

Absolutely. In fact, Nie mam czasu is the most neutral and common version.

Use:

• Nie mam czasu when you simply want to say I don’t have time
• Ja też nie mam czasu when you want to say I don’t have time either / me neither

So the full sentence is especially useful when responding to what someone else has said.

Example:

• On nie ma czasu.
• Ja też nie mam czasu.

Yes. Polish word order is flexible, but different orders change the emphasis.

The most natural versions are:

• Ja też nie mam czasu
• Też nie mam czasu
• Nie mam też czasu

These are similar, but not identical in emphasis:

• Ja też nie mam czasu → emphasis on I too
• Też nie mam czasu → natural I also don’t have time
• Nie mam też czasu → often sounds like I also don’t have time, but with a slightly different focus, depending on context

If you are learning, Ja też nie mam czasu and Też nie mam czasu are very safe choices.

Yes. With verbs, nie is normally written as a separate word.

So:

• mam → nie mam
• wiem → nie wiem
• robię → nie robię

This is different from some adjectives or nouns, where nie is often written together, but with verbs you should usually expect it to be separate.

Też is pronounced roughly like tesh, but with a voiced final sound in careful pronunciation.

A simple learner-friendly approximation:

• też ≈ tesh

More exactly:

• t as in English top
• e like e in bed
• ż is like the s in measure

So też sounds close to tezh.

A simple approximation is:

ya tesh nyeh mahm CHA-soo

More carefully:

• Ja = ya
• też = tesh / tezh
• nie = nye
• mam = mahm
• czasu = CHA-soo

Stress in Polish usually falls on the second-to-last syllable of a word:

• cza-su → stress on cza

The dictionary form is czas.

You look nouns up in the dictionary in the nominative singular form, so:

• dictionary form: czas
• form used here: czasu

That means when learning vocabulary, you should memorize the noun as czas, and then learn that after negation it can become czasu.

Yes, you can, although też is usually more common and conversational here.

• Ja też nie mam czasu = very natural
• Ja także nie mam czasu = also correct, a bit more formal or careful

For everyday speech, też is probably the best choice.

Even if the direct word-for-word meaning is something like I also do not have time, the most natural English translation in conversation is often:

• I don’t have time either
• I don’t have time either, too is not natural
• Me neither may be the natural reply in some contexts, though it is not a full sentence

So this Polish sentence is often used the same way English speakers say Me neither or I don’t have time either.
