Cumujemy przy przystani kajakowej.

Cumujemy is the 1st person plural present tense form of the verb cumować.

So:

• cumuję = I am mooring
• cumujesz = you are mooring
• cumujemy = we are mooring

In Polish, the subject pronoun my = we is usually omitted, because the verb ending already shows who is doing the action.

So Cumujemy by itself already means we are mooring.

Cumować is a fairly specific nautical/water-transport verb. It means:

• to moor
• to dock
• to tie up a boat

It is more specific than a general verb like zatrzymywać się (to stop).

So this sentence suggests that we are bringing a boat alongside and securing it near the landing/place for kayaks.

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

The ending -my in cumujemy already tells you the subject is we.

So:

• Cumujemy przy przystani kajakowej. = We are mooring at/by the kayak landing.
• My cumujemy przy przystani kajakowej. also works, but my adds emphasis, like we are the ones mooring.

The preposition przy usually means:

• by
• next to
• near
• sometimes at, depending on context

With boats, przy przystani suggests being alongside or by the landing/marina/dock area.

So przy przystani kajakowej is something like:

• by the kayak landing
• at the kayak dock
• next to the kayak marina

The best English translation depends on context.

Because przy requires the locative case in Polish.

The dictionary form is:

• przystań = landing / marina / dock

After przy, it changes to the locative:

• przy przystani

So this is a normal case change:

• przystań → przystani

The basic form is przystań.

This is a feminine noun, even though it does not end in -a. That can surprise English speakers.

Here are a few forms:

• przystań = nominative singular
• przystani = genitive singular
• przystani = dative singular
• przystani = locative singular
• przystanią = instrumental singular

In this sentence, przystani is locative singular because of przy.

Kajakowej comes from the adjective kajakowy = kayak-related.

It agrees with przystani in:

• gender: feminine
• number: singular
• case: locative

So:

• przystań kajakowa = kayak landing / kayak marina
• przy przystani kajakowej = at/by the kayak landing

This is adjective agreement, which is a very important part of Polish grammar.

Not literally. In Polish, adjectives like kajakowy / kajakowa / kajakowe often mean:

• for kayaks
• related to kayaking
• used by kayaks/kayakers

So przystań kajakowa means a landing, dock, or marina intended for kayaks.

It does not mean the place is somehow made of kayaks or owned by kayaks.

Sometimes yes, but the meaning shifts slightly.

• przy przystani kajakowej = by / next to / alongside the kayak landing
• na przystani kajakowej = at/on the landing area itself

With cumować, przy feels very natural because mooring often means being alongside something.

So in this sentence, przy is a good choice.

Here it is present tense: we are mooring or we moor.

The verb cumować is imperfective, so its present tense normally refers to:

• an action happening now
• a repeated/habitual action

If you want the idea of successfully mooring / finishing the mooring, Polish often uses a perfective verb such as zacumować.

For example:

• Cumujemy. = We are mooring.
• Zacumujemy. = We will moor / We will tie up.

No, Polish word order is fairly flexible.

The neutral order here is:

• Cumujemy przy przystani kajakowej.

But you could also say:

• Przy przystani kajakowej cumujemy.

That version puts more emphasis on where you are mooring.

Because Polish uses endings to show grammatical roles, word order is often used more for focus and emphasis than for basic grammar.

Polish has no articles like a or the.

So:

• przystań can mean a landing or the landing
• przystań kajakowa can mean a kayak landing or the kayak landing

Context tells you which meaning is intended.

That is why przy przystani kajakowej can be translated as:

• by a kayak landing
• by the kayak landing

depending on the situation.

A rough pronunciation guide is:

tsu-MOO-ye-my pshee pshi-STAH-nee ka-ya-KO-vej

A few useful notes:

• Polish c sounds like ts, so cumujemy starts with ts, not like English k.
• rz in przy and przystani sounds roughly like zh/sh depending on how you approximate it.
• j in Polish sounds like English y in yes.
• w in Polish sounds like English v, so kajakowej ends with a v sound before the final vowel.

Yes, it is natural, especially in a boating or kayaking context.

It sounds like something you might say when talking about bringing a boat in and tying it up near a kayak landing or station.

Depending on context, other natural options might include:

• Przybijamy do przystani kajakowej.
• Cumujemy przy pomoście kajakowym.

But Cumujemy przy przystani kajakowej. is perfectly good Polish.
