Potrzebujemy pewności.

Potrzebujemy is the 1st person plural present-tense form of potrzebować = to need.

So:

• potrzebuję = I need
• potrzebujesz = you need
• potrzebuje = he/she/it needs
• potrzebujemy = we need
• potrzebujecie = you all need
• potrzebują = they need

The ending -my is a very common clue that the verb means we are doing the action.

In Polish, the subject pronoun is often omitted because the verb ending already shows who is doing the action.

So:

• Potrzebujemy pewności. = We need certainty.
• My potrzebujemy pewności. also means We need certainty, but my adds emphasis, like we in we need certainty.

Polish usually leaves out pronouns unless they are needed for contrast, emphasis, or clarity.

Because the verb potrzebować normally takes the genitive case, not the nominative or accusative.

The basic dictionary form is:

• pewność = certainty, confidence

But after potrzebować, it changes to the genitive:

• potrzebować pewności = to need certainty

So in this sentence:

• Potrzebujemy pewności.

Here pewności is the correct case form required by potrzebujemy.

Here it is genitive singular.

The noun is:

• pewność — nominative singular

After potrzebować, it becomes:

• pewności — genitive singular

This is a very useful pattern to remember:

• potrzebować czasu = to need time
• potrzebować pomocy = to need help
• potrzebować pewności = to need certainty

So the important rule is:

potrzebować + genitive

Pewność can mean things like:

• certainty
• confidence
• assurance
• being sure

The exact English translation depends on context.

In Potrzebujemy pewności, it most naturally means something like:

• We need certainty
• We need assurance
• We need to be sure

So pewność is the state of being sure about something.

Yes, Potrzebujemy pewności. is natural and correct.

It sounds fairly neutral and can work in many contexts, for example when people want clear confirmation before making a decision.

Depending on context, Polish speakers might also say:

• Musimy mieć pewność. = We must be sure / We need to be sure.
• Chcemy mieć pewność. = We want to be sure.
• Potrzebujemy większej pewności. = We need more certainty.

But the original sentence is completely normal.

A rough pronunciation guide for an English speaker is:

• Potrzebujemy ≈ poh-tsheh-boo-YEH-my
• pewności ≈ pehv-NO-shee

A few useful pronunciation notes:

• rz is usually pronounced like the zh sound in measure
• trz in potrz- is a cluster and can be tricky; in real speech it often sounds close to tsh
• w in Polish sounds like English v
• ś / si before a vowel gives a soft sh-like sound; in -ści it sounds roughly like shchee or shee/chti depending on the exact word and speaker

So the whole sentence is roughly:

poh-tsheh-boo-YEH-my pehv-NO-shee

Yes. Polish word order is more flexible than English because the grammatical roles are shown by endings.

The neutral order is:

• Potrzebujemy pewności.

But you could also hear:

• Pewności potrzebujemy.

This version puts more emphasis on pewności — as if saying It’s certainty that we need.

So the original sentence is the most neutral, but other orders are possible for emphasis or style.

No. In this sentence, it is understood as singular: certainty.

The form pewności can look ambiguous because Polish endings sometimes overlap between different cases and numbers. But here the grammar tells us what it is:

• potrzebować requires genitive
• pewność in genitive singular is pewności

So in this sentence it means of certainty, not certainties.

Not exactly. It is not the best equivalent here.

If you want to say We need to be sure, a more natural Polish sentence would be:

• Musimy być pewni.
• Potrzebujemy mieć pewność.

Why? Because potrzebować usually combines more naturally with a noun phrase, as in:

• potrzebujemy pewności

Using potrzebować directly before być is not the most natural choice in this context.

So:

• Potrzebujemy pewności. = We need certainty / assurance.
• Musimy być pewni. = We must be sure.
• Potrzebujemy mieć pewność. = We need to be sure.

The dictionary form is pewność.

When learning Polish nouns, it is best to memorize them in the dictionary form and, if possible, also note how they behave in common patterns.

For this noun:

• pewność = nominative singular
• pewności = genitive singular, dative singular, locative singular, and also some plural forms depending on context

In this sentence, though, you only need to remember:

• dictionary form: pewność
• after potrzebować: pewności

Yes — the most useful takeaway is this grammar pattern:

potrzebować + genitive

Examples:

• Potrzebuję czasu. = I need time.
• Potrzebujesz pomocy. = You need help.
• Potrzebujemy pewności. = We need certainty.

So if you remember just one thing from this sentence, remember that potrzebować does not usually take the basic noun form. It usually requires the genitive.
