Sprawdzam dostępność.

In Polish, the subject pronoun is often omitted because the verb ending already shows who is doing the action.

• sprawdzam = I check / I am checking
• the ending -am tells you it is 1st person singular: I

So ja sprawdzam dostępność is possible, but ja is usually unnecessary unless you want emphasis, contrast, or clarity.

For example:

• Sprawdzam dostępność. = I’m checking availability.
• Ja sprawdzam dostępność, a on ceny. = I’m checking availability, and he’s checking prices.

Sprawdzam is the 1st person singular present tense form of the verb sprawdzać, which is an imperfective verb.

That means:

• sprawdzać = to check, to be checking
• sprawdzam = I check / I am checking

A few present-tense forms of sprawdzać:

• sprawdzam = I check
• sprawdzasz = you check
• sprawdza = he/she/it checks
• sprawdzamy = we check
• sprawdzacie = you all check
• sprawdzają = they check

It can mean both.

Polish present tense often covers both the English simple present and present continuous, and context tells you which is meant.

So:

• Sprawdzam dostępność. can mean I check availability or, more naturally in many situations, I’m checking availability.

In real-life use, this sentence often sounds like something someone says right now, so I’m checking availability is a very natural translation.

Because dostępność is the noun meaning availability, and here it is the direct object of sprawdzam.

The verb sprawdzać normally takes a direct object in the accusative case.
However, with this noun, the accusative singular looks the same as the nominative singular.

So:

• dostępność = nominative
• dostępność = accusative as well

That is why the form does not change.

It comes from the adjective dostępny, which means available.

The suffix -ość often turns an adjective into an abstract noun, similar to English -ness or sometimes -ity.

So:

• dostępny = available
• dostępność = availability

Other similar patterns:

• ważny = important → ważność = validity / importance
• łatwy = easy → łatwość = ease

So dostępność is literally the quality of being available.

This is a difference of aspect and tense.

• sprawdzam comes from sprawdzać and is imperfective
• sprawdzę comes from sprawdzić and is perfective

In practice:

• sprawdzam = I am checking / I check
• sprawdzę = I will check

Why? In Polish, perfective verbs do not normally have a true present meaning. Their present-looking forms usually refer to the future.

So:

• Sprawdzam dostępność. = I’m checking availability.
• Sprawdzę dostępność. = I’ll check availability.

A learner will usually want to pay attention to these parts:

• sprawdzam roughly sounds like spra-vdzam
• dostępność roughly sounds like do-stem-pnoshch

A few details:

• w in Polish sounds like English v
• rz usually sounds like zh or merges with ż
• ę is a nasal vowel, but before some consonants it is often pronounced more like em/en
• ść at the end sounds something like a soft shch

So dostępność is often heard approximately as dostempnoshch, though exact pronunciation depends on speech style.

The letter ę is a nasal vowel, but in normal pronunciation it often changes depending on what follows.

In dostępność, the ę comes before pn, so in everyday speech it is often pronounced approximately like em.

So:

• spelling: dostępność
• common pronunciation: roughly dostempność

This is normal in Polish pronunciation. The spelling stays ę, even when the sound shifts in connected speech.

Yes, Polish word order is fairly flexible, though some orders sound more neutral than others.

The most neutral version here is:

• Sprawdzam dostępność.

You could also say:

• Dostępność sprawdzam.

But that sounds more marked, as if you are emphasizing availability specifically, or contrasting it with something else.

Because Polish uses case endings, word order is often used for emphasis, focus, or style, not just for grammar.

No, it would not be wrong.

It is just less neutral than Sprawdzam dostępność.

Using ja adds emphasis, for example:

• Ja sprawdzam dostępność, nie rezerwuję jeszcze.
  = I’m checking availability, not booking yet.

So:

• Sprawdzam dostępność. = normal, neutral
• Ja sprawdzam dostępność. = correct, but more emphatic

Yes, very natural.

It sounds like something a person might say in a shop, office, hotel, clinic, or customer service context when they are checking whether something is available.

For example:

• a hotel receptionist checking room availability
• a store employee checking whether an item is in stock
• someone checking appointment availability

It is short, natural, and common in practical situations.
