Popraw tę literówkę, zanim wyślesz formularz.

Popraw is the imperative form of the verb poprawić, meaning correct, fix, or improve.

So Popraw tę literówkę means Correct this typo or Fix this typo.

In this sentence, popraw is a command addressed to one person.

Related imperative forms:

• popraw — correct! (to one person)
• poprawcie — correct! (to more than one person)
• niech pan/pani poprawi — a more polite/formal way

Because literówkę is the direct object of the verb popraw. In Polish, direct objects often take the accusative case.

The dictionary form is:

• ta literówka — this typo (nominative)

But after a verb like poprawić (to correct), it changes to accusative:

• tę literówkę — this typo (accusative)

So:

• Ta literówka jest poważna. — This typo is serious.
• Popraw tę literówkę. — Correct this typo.

This is a normal accusative singular ending for many feminine nouns in Polish.

The basic form is:

• literówka — typo

In the accusative singular:

• literówkę

A very common pattern is:

• nominative -a → accusative -ę

For example:

• książka → książkę
• kawa → kawę
• literówka → literówkę

So Popraw tę literówkę uses both:

• tę — accusative form of ta
• literówkę — accusative form of literówka

Literówka means a typo — a small mistake in writing or typing, such as a wrong letter, missing letter, or extra letter.

It comes from litera (letter), so the idea is something like a letter mistake.

Examples:

• Znalazłem literówkę w mailu. — I found a typo in the email.
• To tylko literówka. — It’s just a typo.

Yes, it looks like a present-tense form, but with a perfective verb like wysłać (to send), those forms are used to talk about the future.

So:

• wyślesz literally is the 2nd person singular form of wysłać
• with a perfective verb, it means you will send

That is why:

• zanim wyślesz formularz = before you send the form

This is very common in Polish:

• zrobisz = you will do
• napiszesz = you will write
• wyślesz = you will send

After zanim (before), Polish normally uses a finite verb form, not an imperative.

So the structure is:

• zanim + clause
• zanim wyślesz formularz — before you send the form

Also, wyślijesz is not a correct form. The correct verb is:

• infinitive: wysłać
• future/perfective form: wyślesz

So:

• wyślesz = you will send
• not wyślijesz

Because formularz is a masculine inanimate noun, and in the accusative singular, masculine inanimate nouns usually look the same as in the nominative.

So:

• nominative: formularz
• accusative: formularz

That is why we say:

• Wyślesz formularz. — You will send the form.

Compare that with a masculine animate noun, where accusative often changes:

• student → studenta

But:

• formularz → formularz

Zanim means before and introduces a subordinate clause.

So:

• Popraw tę literówkę, zanim wyślesz formularz.
• Correct this typo before you send the form.

It connects two actions:

1. first: correct the typo
2. later: send the form

So the sentence tells you the order in which things should happen.

Because zanim introduces a subordinate clause, and in Polish these clauses are normally separated by a comma.

So:

• Popraw tę literówkę, zanim wyślesz formularz.

This is standard Polish punctuation.

You will see the same with other conjunctions introducing subordinate clauses, for example:

• Powiedz mi, kiedy przyjdziesz. — Tell me when you’ll come.
• Zadzwoń, jeśli będziesz miał czas. — Call if you have time.

It is speaking to one person.

You can tell from the verb forms:

• popraw — imperative for one person
• wyślesz — you will send for one person

If you were speaking to more than one person, you would say:

• Poprawcie tę literówkę, zanim wyślecie formularz.

Yes, Polish word order is fairly flexible, though some versions sound more natural than others.

The original sentence:

• Popraw tę literówkę, zanim wyślesz formularz.

This is the most natural neutral order.

You could also say:

• Zanim wyślesz formularz, popraw tę literówkę.

This means the same thing, but puts more focus on before sending the form.

So the choice of word order often affects emphasis, not the core meaning.
