Potřebuji pár kopií.

Potřebuji means I need.

It is the 1st person singular present tense form of the verb potřebovat, which means to need. So:

• potřebovat = to need
• potřebuji = I need

In this sentence, it works just like English I need.

Czech often leaves out subject pronouns when they are not needed.

The ending in potřebuji already tells you the subject is I, so já is unnecessary here.

So both of these are possible:

• Potřebuji pár kopií. = I need a few copies.
• Já potřebuji pár kopií. = I need a few copies.

The version with já sounds more emphatic, as if you are stressing I.

Pár can mean different but related things depending on context:

• a pair
• a couple of
• a few

In Potřebuji pár kopií, it means a few or a couple of, not necessarily exactly two.

So the sentence is understood as I need a few copies.

If you really wanted to emphasize exactly two copies, Czech would more naturally use dvě kopie.

Because after pár, Czech normally uses the genitive plural.

The basic dictionary form is:

• kopie = copy

But after quantity words such as pár, několik, pět, and so on, the following noun usually changes form:

• pár kopií = a few copies
• několik kopií = several copies
• pět kopií = five copies

So:

• kopie = basic form
• kopií = genitive plural

That is why pár kopie would be incorrect.

It is natural and correct, but it can sound a bit direct in situations like a shop or office.

If you want to sound more polite, Czech often uses a softer form such as:

• Potřeboval bych pár kopií, prosím. for a man
• Potřebovala bych pár kopií, prosím. for a woman

This is closer to I would like / I would need a few copies, please.

So:

• Potřebuji pár kopií. = correct, neutral, direct
• Potřeboval bych pár kopií, prosím. = more polite

Yes. Czech word order is more flexible than English word order.

The neutral, straightforward version is:

• Potřebuji pár kopií.

You can also say:

• Pár kopií potřebuji.

This version puts more emphasis on pár kopií, as if contrasting it with something else.

Even though Czech allows more flexibility, the original order is the most natural in ordinary conversation.

A rough pronunciation guide is:

• Potřebuji ≈ PO-trzhe-boo-yi
• pár ≈ paar
• kopií ≈ KO-pi-ee

A few helpful points:

• Czech stress is usually on the first syllable of each word.
• á in pár is a long vowel.
• kopií has three syllables: ko-pi-í.
• The hardest sound for many learners is ř in potřebuji. It is a special Czech sound, something like a mix of r and zh. If you cannot say it perfectly yet, that is very normal.

The dictionary form is kopie.

So if you look it up in a dictionary, you should search for:

• kopie = copy

In the sentence, it appears as kopií because the grammar requires the genitive plural after pár.
