Sygnatura pokazuje dział i regał.

In this kind of context, sygnatura usually means a call number, shelfmark, or reference code used to identify where something belongs, especially in a library, archive, or storage system.

So it is not usually a signature in the English sense of a person writing their name, even though the words look related.

Pokazuje is the 3rd person singular form of the verb pokazywać/pokazać, meaning shows.

Here the subject is sygnatura, which is:

• singular
• feminine

So the verb must match a singular subject:

• ja pokazuję = I show
• on/ona/ono pokazuje = he/she/it shows
• oni/one pokazują = they show

In this sentence, sygnatura pokazuje... = the call number shows...

They are in the accusative case because they are the direct objects of pokazuje.

However, both dział and regał are:

• masculine
• inanimate
• singular

For many masculine inanimate nouns in Polish, the accusative singular is the same as the nominative singular.

So:

• dział → accusative dział
• regał → accusative regał

That is why they look unchanged.

Polish does not use articles like English a/an and the.

So a sentence like Sygnatura pokazuje dział i regał can mean something like:

• The call number shows the section and the shelf
• or, depending on context, A call number shows a section and a shelf

Polish usually leaves that distinction to the context.

A helpful approximate pronunciation is:

sig-na-TOO-ra

A few details:

• y in sy- is not exactly English ee or i; it is a short Polish vowel, somewhat like the vowel in bit, but tenser and farther back.
• Stress in Polish is usually on the second-to-last syllable, so here the stress is on tu: sygnaTUra.

These words can be tricky because of dz and especially ł.

• dział is roughly jya-w or dzhyaw, depending on how carefully it is pronounced
• regał is roughly RE-gaw

Important point:

• Polish ł is pronounced like English w, not like the English l

So:

• regał does not end with an l sound
• it ends with a w-like sound

Also, dz at the start of dział is pronounced together as one consonant cluster.

They refer to different kinds of location information.

• dział = section, department, or category area
• regał = shelf unit, bookcase, or rack

So the sentence suggests that the sygnatura tells you both:

• which section something is in
• and which shelf/bookcase to look at

Yes. Polish word order is more flexible than English because grammatical roles are shown partly by endings, not only by position.

The neutral order here is:

Sygnatura pokazuje dział i regał.

But other orders are possible for emphasis, for example:

• Dział i regał pokazuje sygnatura.

That sounds more marked and would usually emphasize dział i regał.

So the original sentence is the most natural basic order for a learner to remember: subject + verb + object

Sygnatura is feminine.

You can usually recognize many feminine nouns because they end in -a, though there are exceptions in Polish.

Yes, it matters because gender affects:

• adjective agreement
• past tense forms
• pronouns
• sometimes numeral constructions

In this present-tense sentence, the verb form pokazuje does not show feminine gender very clearly by itself, but the subject is still grammatically feminine.

Yes, i is the basic Polish word for and.

In this sentence:

dział i regał = section and shelf

Polish also has oraz, which can also mean and, but it is usually a bit more formal. In everyday simple sentences, i is the normal choice.
