Ta wyszukiwarka pomaga mi znaleźć link do kursu polskiego.

Because wyszukiwarka is a feminine singular noun, so the demonstrative has to agree with it.

• ten = masculine
• ta = feminine
• to = neuter

So:

• ta wyszukiwarka = this search engine/tool

This is normal adjective/demonstrative agreement in Polish.

Usually ta is best translated as this, but in real usage Polish ten / ta / to can sometimes cover both this and that, depending on context.

So ta wyszukiwarka most naturally means this search engine, but in some contexts English might prefer that search engine.

Wyszukiwarka usually means search engine or search tool.

It comes from the verb family related to wyszukiwać / wyszukać, meaning to search out or to find by searching.

Depending on context, wyszukiwarka could mean:

• an internet search engine
• a search function on a website
• a search tool in an app or program

Mi is in the dative case.

The verb pomagać means to help, and in Polish it normally takes the person being helped in the dative:

• pomagać komu? czemu? = to help whom? what?

So:

• pomaga mi = helps me
• literally: helps to me is not how you translate it, but the grammar works that way

Examples:

• Pomaga mi uczyć się polskiego. = It helps me learn Polish.
• Ona pomaga bratu. = She helps her brother.

Both can mean me, but mi is the normal unstressed form, and mnie is usually used for emphasis, contrast, or after some prepositions.

So in a neutral sentence:

• Ta wyszukiwarka pomaga mi znaleźć link... = natural

If you wanted emphasis, you might say:

• Ta wyszukiwarka pomaga mnie, nie tobie — actually this is not correct with pomagać, because pomagać requires dative, so the emphatic form would be mnie in dative-like function only in certain contexts? Better to think of mi as the normal choice here.

In everyday neutral Polish, pomaga mi is exactly what you expect.

Because Polish uses the infinitive directly after many verbs, including pomagać.

English says:

• helps me to find
• or helps me find

Polish says:

• pomaga mi znaleźć

There is no extra particle like English to before the infinitive.

This is about aspect, which is very important in Polish verbs.

• znaleźć = perfective = to find, as a completed result
• znajdować / znajdować się is a different verb family; the imperfective partner of znaleźć is usually znajdować in some uses, but for finding something successfully, znaleźć is the natural choice when you mean a single completed action

Here the sentence means the search engine helps me successfully find a link, so znaleźć makes sense.

If you used an imperfective verb, it would sound more like an ongoing or repeated process, not one completed result.

Here link is in the accusative singular, because it is the direct object of znaleźć:

• znaleźć co? = to find what?
• link

For a masculine inanimate noun like link, the accusative singular looks the same as the nominative singular:

• nominative: link
• accusative: link

So even though the form does not change, the case function is still accusative.

Because in Polish the noun link commonly goes with the preposition do when you mean a link to something.

So:

• link do strony = a link to a website/page
• link do filmu = a link to a film/video
• link do kursu = a link to a course

After do, Polish uses the genitive case, which is why kurs becomes kursu.

Here polskiego is the genitive singular form of polski and it agrees with kursu.

Because do requires the genitive, both words change:

• kurs polski would be nominative-style agreement
• do kursu polskiego is genitive

In meaning, kurs polskiego usually means a Polish course or more precisely a course of the Polish language.

Very often this is a shortened version of:

• kurs języka polskiego = a Polish language course

So link do kursu polskiego is naturally understood as a link to a Polish course or a link to a Polish language course.

In Polish, adjectives can come before or after the noun, but the most neutral pattern is often adjective + noun. However, with some expressions, especially where English might use of, Polish often uses a noun phrase like:

• kurs polskiego
• nauczyciel angielskiego
• lekcja niemieckiego

In these cases, the adjective after the noun often sounds very natural and can imply something like course of Polish, teacher of English, lesson of German.

So kurs polskiego is a standard and natural expression.

Not completely. Polish word order is more flexible than English because case endings show grammatical relationships.

The given order:

• Ta wyszukiwarka pomaga mi znaleźć link do kursu polskiego.

is neutral and natural.

You can change the order for emphasis, for example:

• Mi ta wyszukiwarka pomaga znaleźć link do kursu polskiego.
• Link do kursu polskiego ta wyszukiwarka pomaga mi znaleźć.

But those versions sound more marked or emphatic. For a learner, the original sentence is the safest and most natural choice.

Yes. It is very common to use:

• pomagać komuś + infinitive

meaning:

• to help someone do something

Examples:

• To pomaga mi zrozumieć gramatykę. = This helps me understand grammar.
• Aplikacja pomaga im uczyć się słówek. = The app helps them learn vocabulary.
• Nauczyciel pomaga nam mówić po polsku. = The teacher helps us speak Polish.

So pomaga mi znaleźć is a very standard structure.
