Prosím vás, neviděli jste můj batoh s tužkou, gumou a malým dárkem pro učitelku?

Here Prosím vás is a polite attention-getter, like Excuse me or Please at the start of a question.

Literally, it comes from prosím = I ask / please, and vás = you. But in real speech, the whole phrase is idiomatic. It often introduces a request or question politely:

• Prosím vás, kde je nádraží? = Excuse me, where is the station?
• Prosím vás, nevíte... ? = Excuse me, do you know... ?

So in this sentence, it is not the main content of the question; it just makes the question polite.

Because Czech uses the past tense where English often uses have you seen.

So:

• Viděli jste...? = Did you see...? / Have you seen...?
• Neviděli jste...? = Haven’t you seen...?

Czech does not have a direct present perfect tense like English have seen, so the past tense often covers both meanings depending on context.

Here the speaker is asking whether the listeners saw the backpack at some point before now.

A negative question like Neviděli jste...? is very common in Czech when asking about something lost or missing. It sounds natural and polite, similar to English:

• Haven’t you seen my keys?
• You haven’t seen my bag, have you?

It does not necessarily imply the speaker expects the answer to be yes. It is just a very normal way to ask.

A positive version, Viděli jste můj batoh?, is also possible, but Neviděli jste...? often sounds a bit softer or more natural in this situation.

As written, this sentence is addressed to more than one person, or to a group.

The clue is neviděli jste:

• jste = you are / you have for you plural or formal you
• viděli = plural past form

So this version fits a group, especially a mixed group or a group of men.

If you were speaking politely to one man, you would normally say:

• Prosím vás, neviděl jste můj batoh...?

To one woman:

• Prosím vás, neviděla jste můj batoh...?

To a group of only women:

• Prosím vás, neviděly jste můj batoh...?

The backpack is the direct object, so it is in the accusative case.

However, batoh is a masculine inanimate noun, and in the singular its accusative form is the same as its nominative form. So you do not see a change:

• nominative: můj batoh
• accusative: můj batoh

That is why it looks unchanged.

If it were a noun with a different accusative form, you would see the change more clearly.

Because they come after the preposition s, which here means with, and s requires the instrumental case.

So:

• tužka → s tužkou
• guma → s gumou
• malý dárek → s malým dárkem

The adjective must match the noun, so:

• malý → malým
• dárek → dárkem

This whole phrase means with a pencil, an eraser, and a small gift.

Because the preposition pro takes the accusative case, not the dative.

So:

• base form: učitelka = teacher (female)
• after pro: pro učitelku = for the teacher

Examples:

• dárek pro učitelku = a gift for the teacher
• květiny pro maminku = flowers for Mom

If you said učitelce, that would be a different case and would not be correct after pro.

Yes. It describes which backpack the speaker means: the one with a pencil, an eraser, and a small gift for the teacher.

So the structure is:

• můj batoh
• s tužkou, gumou a malým dárkem pro učitelku

Together: my backpack with a pencil, an eraser, and a small gift for the teacher

In natural interpretation, this usually means those things are in the backpack or are part of what is with it.

Because Czech has no articles.

English distinguishes between:

• a backpack
• the backpack
• a pencil
• the pencil

Czech usually does not mark that difference with a separate word. Context tells you whether something is definite or indefinite.

So:

• batoh can mean a backpack or the backpack
• tužka can mean a pencil or the pencil

In this sentence, English naturally uses my backpack, a pencil, an eraser, a small gift, but Czech does not need articles for that.

The sentence as written is very natural, but Czech word order is more flexible than English word order.

Standard, neutral order here is:

• Prosím vás, neviděli jste můj batoh s tužkou, gumou a malým dárkem pro učitelku?

You could move some parts around for emphasis, but not every version sounds equally natural. For example, putting Prosím vás at the beginning is very common because it sets up the polite question.

Czech word order often changes to show emphasis, topic, or what is already known, while English relies more heavily on fixed word order.

Here guma means eraser.

Depending on the variety of English:

• in American English: eraser
• in British English: often rubber

So:

• s gumou = with an eraser / with a rubber

This is a useful everyday school word in Czech.
