Bierzemy rzutkę ratowniczą, tym bardziej że kajakarz jest zmęczony.

In Polish, the verb usually already tells you who the subject is.
Bierzemy means we take / we are taking / we’re taking.

So the pronoun my (we) is normally omitted unless you want extra emphasis or contrast:

• Bierzemy rzutkę ratowniczą. = We’re taking the rescue throw bag.
• My bierzemy rzutkę ratowniczą, a oni apteczkę. = We’re taking the rescue throw bag, and they’re taking the first-aid kit.

This is very common in Polish.

Polish often uses the present tense to talk about a planned or immediate future action, especially in spoken language.

So:

• Bierzemy rzutkę ratowniczą.

can mean:

• We’re taking the rescue throw bag
• Let’s take the rescue throw bag
• We’ll take the rescue throw bag

depending on context.

This works because brać is an imperfective verb, and the present tense can sound very natural for a current decision or ongoing action.

Rzutka ratownicza is a piece of rescue equipment used in water rescue. In English, it is often called a throw bag or rescue throw line.

Breaking it down:

• rzutka = something for throwing; in rescue contexts, a throw line / throw bag
• ratownicza = rescue, lifesaving

So together it means a rescue throwing device, usually a bag with rope inside that you throw to someone in the water.

Because the phrase is the direct object of bierzemy (we take), it has to be in the accusative case.

The basic dictionary form is:

• rzutka ratownicza

But after brać (to take), it changes to accusative:

• bierzemy rzutkę ratowniczą

For feminine singular nouns ending in -a, the accusative usually changes:

• noun: -a → -ę
• adjective: -a → -ą

So:

• rzutka → rzutkę
• ratownicza → ratowniczą

Because adjectives in Polish must agree with the noun they describe in:

• gender
• number
• case

So if the noun changes to accusative singular feminine, the adjective has to match it.

Here:

• nominative: rzutka ratownicza
• accusative: rzutkę ratowniczą

This kind of matching is one of the central features of Polish grammar.

Tym bardziej że is a fixed expression meaning something like:

• especially since
• all the more so because
• particularly because

It introduces an additional reason that strengthens what was said before.

So:

• Bierzemy rzutkę ratowniczą, tym bardziej że kajakarz jest zmęczony.

means roughly:

• We’re taking the rescue throw bag, especially since the kayaker is tired.

Literally, tym bardziej means all the more / even more, and że introduces the clause that/because.

Not exactly. They are similar, but not identical.

• bo = because
• ponieważ = because / since (more formal)
• tym bardziej że = especially since / all the more because

So tym bardziej że adds the idea that this reason makes the previous statement even stronger.

Compare:

• Bierzemy rzutkę ratowniczą, bo kajakarz jest zmęczony.
  We’re taking the rescue throw bag because the kayaker is tired.

• Bierzemy rzutkę ratowniczą, tym bardziej że kajakarz jest zmęczony.
  We’re taking the rescue throw bag, especially since the kayaker is tired.

The second one sounds stronger and more emphatic.

Because tym bardziej że is a set phrase. In this structure, że is the normal word that introduces the subordinate clause.

So you learn it as one unit:

• tym bardziej że ...

For example:

• Pójdę, tym bardziej że mnie zaprosili. = I’ll go, especially since they invited me.
• Musimy uważać, tym bardziej że jest ślisko. = We have to be careful, especially since it’s slippery.

Because kajakarz is the subject of the second clause:

• kajakarz jest zmęczony = the kayaker is tired

Subjects are normally in the nominative case, which is the dictionary form.

So:

• kajakarz = nominative singular masculine

If it were an object, it might change case, but here it is simply the person who is tired.

Because zmęczony agrees with kajakarz, which is:

• masculine
• singular
• nominative

After być (to be), Polish commonly uses an adjective in the nominative to describe the subject:

• kajakarz jest zmęczony = the kayaker is tired
• kobieta jest zmęczona = the woman is tired
• dziecko jest zmęczone = the child is tired

So the ending changes depending on gender:

• masculine: zmęczony
• feminine: zmęczona
• neuter: zmęczone

In normal usage, kajakarz means kayaker or canoeist/paddler in a kayak context, depending on context. Most naturally in English here, kayaker is the best translation.

It refers to a person using a kayak. In practical speech, it doesn’t necessarily imply a professional athlete; it can just mean someone who is kayaking.

The infinitive is brać, meaning to take.

Its present-tense forms include:

• biorę = I take
• bierzesz = you take
• bierze = he/she/it takes
• bierzemy = we take
• bierzecie = you all take
• biorą = they take

This verb is worth memorizing because it is very common and not completely regular.

The word order is natural and neutral:

• Bierzemy rzutkę ratowniczą, tym bardziej że kajakarz jest zmęczony.

Polish word order is fairly flexible, but this version sounds clear and standard:

1. main statement
2. added reason

You could move things around in some contexts, but this is the most straightforward way to say it.

A very literal version would be something like:

• We take the rescue throw-bag, all the more because the kayaker is tired.

That is understandable, but it sounds unnatural in English. A more idiomatic translation would be:

• We’re taking the rescue throw bag, especially since the kayaker is tired.
• We’ll take the rescue throw bag, all the more so since the kayaker is tired.

This is a good example of why Polish expressions are often better learned as chunks rather than word-for-word.
