Czy ten termin w środę po południu nadal jest wolny?

Czy is a yes/no question marker. It signals that the speaker is asking something like Is... ? / Are... ? / Do... ?

So:

• Czy ten termin... ? = Is this appointment/slot... ?

In everyday spoken Polish, people sometimes omit czy and just use question intonation:

• Ten termin w środę po południu nadal jest wolny?

But with czy, the sentence sounds clearer and more standard.

In this sentence, termin means something like:

• appointment
• time slot
• scheduled time
• date/time arranged for something

It does not usually mean English term in the school/semester sense.

Depending on context, termin can also mean:

• a deadline
• an appointment date
• a scheduled session

Here, because the sentence asks whether it is wolny (free/available), termin is best understood as a booking slot or appointment time.

Because termin is a masculine singular noun, and the demonstrative this has to agree with it.

Polish this changes by gender:

• ten for masculine nouns
• ta for feminine nouns
• to for neuter nouns

So:

• ten termin = this appointment/slot

Also, ten termin is in the nominative case here, because it is the subject of jest wolny.

Because after w when talking about on a day of the week, Polish uses the accusative case.

The basic form is:

• środa = Wednesday

But after w in this time expression:

• w środę = on Wednesday

A few similar examples:

• w poniedziałek = on Monday
• we wtorek = on Tuesday
• w czwartek = on Thursday

So w środę is the normal way to say on Wednesday.

Po południu means in the afternoon.

Literally, it comes from the idea of after noon:

• po = after
• południe = noon / midday

The form po południu is a fixed expression in Polish. Learners should usually treat it as one whole phrase meaning in the afternoon.

So:

• w środę po południu = on Wednesday afternoon

Nadal means still.

It shows that the speaker is asking whether the situation remains unchanged:

• Czy ten termin ... nadal jest wolny?
• Is this slot still available?

It suggests that maybe the slot was free before, and now the speaker wants to check if that is still true.

A close alternative is jeszcze, which can also mean still in many contexts:

• Czy ten termin jest jeszcze wolny?

That is also natural.

Because wolny is an adjective meaning free, available, unoccupied, and it agrees with termin.

Since termin is masculine singular, the adjective also takes the masculine singular form:

• wolny

So:

• termin jest wolny = the slot/appointment is free

If the noun were feminine, the adjective would change:

• godzina jest wolna = the hour/time is free

If the noun were plural:

• terminy są wolne = the slots are free

Often yes, but you have to watch the context.

In this sentence, wolny means:

• available
• unbooked
• not occupied

So it is like English free in:

• Is this time slot free?

But wolny can also mean:

• free as in not busy
• free as in not imprisoned
• free as in independent

It does not automatically mean free of charge. For that, Polish often uses phrases like:

• za darmo = free of charge

So here, wolny definitely means available.

No, Polish word order is fairly flexible. But the given order is natural and clear.

The sentence:

• Czy ten termin w środę po południu nadal jest wolny?

is perfectly normal.

You could also hear variations such as:

• Czy ten termin nadal jest wolny w środę po południu?
• Czy w środę po południu ten termin nadal jest wolny?

These versions are still understandable, but they may shift emphasis slightly.

In general:

• Polish often moves parts around for emphasis.
• English is much stricter about word order than Polish.

So the original sentence is a good neutral model to learn.

Because it naturally specifies which appointment/slot we are talking about.

So the structure is roughly:

• Czy = question marker
• ten termin = this slot/appointment
• w środę po południu = on Wednesday afternoon
• nadal jest wolny = is still free

In other words:

• this Wednesday-afternoon slot

Polish often places descriptive information after the noun like this, especially when identifying a particular booking or appointment time.

Sometimes, yes, but be careful.

In some contexts, English date works:

• Do you have a date/appointment available?

However, date in English can sound vague, and it can also mean a calendar date or even a romantic date. In this sentence, better translations are usually:

• appointment
• time slot
• slot
• scheduled time

So date is possible in some contexts, but it is not always the safest choice.

Sometimes yes, but wolny is more natural in many scheduling situations.

Compare:

• termin jest wolny = the slot is free / unbooked
• termin jest dostępny = the slot is available

Both can work, but wolny termin and czy termin jest wolny? are very common when talking about appointments, bookings, and schedules.

So in this sentence, wolny is a very good, natural choice.

It is neutral. It works well in many situations:

• speaking to a receptionist
• emailing a doctor’s office
• asking about a meeting time
• checking availability in a booking context

It is neither very formal nor casual/slangy.

If you wanted to sound a bit more polite in a customer-service or professional setting, you might add something like:

• Czy ten termin w środę po południu nadal jest wolny, proszę?
• Czy ten termin w środę po południu jest jeszcze dostępny?

But the original sentence is already perfectly natural and polite enough in many contexts.
