Spotkajmy się za godzinę.

Spotkajmy is the 1st person plural imperative of spotkać się.

That means it corresponds to English let’s meet.

A useful pattern is:

• spotkać się = to meet
• spotkajmy się = let’s meet

So this is not a plain future tense like we will meet. It is a proposal/suggestion: let’s meet.

Because the verb is spotkać się, not just spotkać.

This is very important:

• spotkać kogoś = to meet someone
• spotkać się z kimś = to meet with someone / to meet someone mutually

In this sentence, się is part of the verb meaning. It gives the idea of meeting each other.

So:

• Spotkajmy się = Let’s meet
• without się, the meaning would change and the sentence would not express the same thing.

In Polish, za + accusative is the normal way to say in ... time when you mean from now.

So:

• za minutę = in a minute
• za godzinę = in an hour
• za tydzień = in a week

Here, za godzinę means one hour from now.

By contrast, w often means in/inside, or it can be used with clock times or dates in other structures, but not usually for this exact from now meaning.

So for in an hour = za godzinę.

Because za in this time expression takes the accusative case.

The noun godzina is feminine, and its singular accusative form is godzinę.

So:

• nominative: godzina
• accusative: godzinę

That is why you get:

• za godzinę

This is a very common pattern with time expressions after za.

Yes — but it means something slightly different.

• Spotkajmy się za godzinę. = Let’s meet in an hour.
  • a suggestion or proposal
• Spotkamy się za godzinę. = We’ll meet in an hour.
  • a statement about a future meeting

So the difference is mainly mood:

• spotkajmy = imperative (let’s ...)
• spotkamy = future (we will ...)

In conversation, the first one sounds like you are proposing the plan. The second sounds more like the plan is already decided.

Because spotkać się is perfective, and here Polish wants a single completed meeting.

• spotkać się = to meet once / to come together successfully
• spotykać się = to meet repeatedly, regularly, or in a more ongoing/habitual sense

In this sentence, you mean one meeting at a specific future time, so spotkać się is the natural choice.

Compare:

• Spotkajmy się jutro. = Let’s meet tomorrow.
• Często się spotykamy. = We often meet.

Yes, it is completely natural and idiomatic.

It is a normal way to suggest a meeting time.

Depending on tone and context, a speaker might also soften it a little:

• Spotkajmy się może za godzinę. = Maybe let’s meet in an hour.
• Może spotkajmy się za godzinę. = Maybe let’s meet in an hour.

But the basic sentence on its own is perfectly normal.

Yes, Polish word order is fairly flexible, although some versions sound more neutral than others.

The most neutral version here is:

• Spotkajmy się za godzinę.

You could also say:

• Za godzinę spotkajmy się.

But that sounds more marked or stylistically shaped, because the time expression is being emphasized.

So for a learner, the safest and most natural order is:

• Spotkajmy się za godzinę.

Roughly, it is pronounced like:

• spot-KAI-mih shyeh

A more careful breakdown:

• Spotkajmy → stress on -kaj-
• się sounds roughly like shyeh, with a nasal quality in careful speech

A more IPA-style approximation is:

• [spɔtˈkajmɨ ɕɛ] or [spɔtˈkajmɨ ɕɛ̃]

A few pronunciation notes:

• Polish stress is usually on the second-to-last syllable, so here: spot-KAJ-my
• się is often pronounced a bit more simply in everyday speech than spelling may suggest
• the cluster in spotk- may feel difficult at first, but it is normal in Polish

It is neutral rather than strongly formal or informal.

It works well in everyday conversation when suggesting a plan.

Still, because it is an imperative form (let’s meet), it can sound a bit direct depending on context. If you want to sound softer or more tentative, Polish often adds words like:

• może = maybe
• dobra / dobrze in conversation, depending on context

For example:

• Może spotkajmy się za godzinę. = Maybe let’s meet in an hour.

So the original sentence is natural and correct, but there are softer variants if needed.
