Obcy stoi przy przystani kajakowej.

In Polish, some adjectives can be used substantively, meaning they function like nouns.

So obcy normally means foreign / strange / unfamiliar, but in a sentence like this it can mean:

• a stranger
• a foreigner
• an unknown person

This is very natural in Polish. It works a bit like English expressions such as the rich, the poor, or the accused, where an adjective behaves like a noun.

Here, obcy is masculine singular and refers to a person.

Polish uses different verbs depending on what you want to express.

• stoi = is standing
• jest = is

So Obcy stoi... specifically tells you the person is in a standing position.

Compare:

• Obcy stoi przy przystani kajakowej. = The stranger is standing by the kayak dock.
• Obcy jest przy przystani kajakowej. = The stranger is at the kayak dock.

The second version only gives location. The first gives both location and posture.

Because the preposition przy requires the locative case.

The basic dictionary form is:

• przystań = dock, landing, marina

But after przy, it changes to the locative:

• przy przystani = by / near the dock

So this is a case-governed form, not a different word.

Kajakowej is also in the locative singular, because it describes przystani, which is in the locative after przy.

The phrase is:

• przystań kajakowa = kayak dock / canoe landing

In the locative singular, both words change:

• przystań kajakowa
• przy przystani kajakowej

So kajakowej agrees with przystani in:

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

This is standard adjective-noun agreement in Polish.

It means a place connected with kayaks or canoes, such as:

• a kayak landing
• a kayak dock
• a canoe landing
• sometimes a small marina for kayaks

The adjective kajakowa comes from kajak = kayak.

So literally it is something like kayak dock or kayak landing place.

The best English translation depends on context, but grammatically it is simply:

• przystań = dock / landing
• kajakowa = kayak-related

Grammatically, yes: obcy is masculine singular.

So the sentence refers to:

• a masculine person, or
• a person treated as masculine in grammar

If you wanted a feminine form, you would say:

• Obca stoi przy przystani kajakowej.

That would mean a strange/unknown woman or a foreign woman depending on context.

Yes. Polish word order is more flexible than English because case endings show grammatical relationships.

The neutral order here is:

• Obcy stoi przy przystani kajakowej.

But you could also say:

• Przy przystani kajakowej stoi obcy.
• Stoi obcy przy przystani kajakowej.

These alternatives are grammatically possible, but the emphasis changes.

For example:

• Przy przystani kajakowej stoi obcy. puts more focus on the location.
• Obcy stoi... starts with the person, so it feels more like the default topic.

Usually przy means something like:

• by
• near
• next to
• at

It often suggests being close to something, though not necessarily touching it.

So in this sentence, przy przystani kajakowej can be understood as:

• by the kayak dock
• near the kayak landing
• at the kayak marina

The most natural English choice depends on the situation.

Polish has no articles.

So obcy can mean:

• a stranger
• the stranger

And przystań kajakowa can mean:

• a kayak dock
• the kayak dock

You determine that from context, not from a word like a or the.

That is one reason Polish sentences can look shorter than English ones.

A rough English-friendly guide would be:

• przystani ≈ pshi-STAH-nee
• kajakowej ≈ ka-ya-KO-vey

A few useful pronunciation notes:

• rz is often pronounced like the zh sound in measure
• y is not exactly like English ee; it is a harder central vowel
• j is like English y
• w in Polish sounds like English v

So kajakowej has a v sound near the end because of w.

Potentially yes, but only if the context supports it.

Obcy can mean:

• foreign
• strange
• stranger
• outsider
• alien

Without context, a learner would usually understand it as a stranger or an unknown person.

If this were from science fiction, Obcy might indeed be understood as an alien. In ordinary everyday language, though, a stranger is more likely.
