Learn Polish: Ktoś teraz wiezie ten towar do sklepu. - Someone is transporting these goods to the store right now.

Wiezie comes from the verb wieźć, which means to transport by vehicle in one specific direction. Because the sentence says teraz (right now) and describes a single, ongoing trip to a specific destination (do sklepu), we use this unidirectional verb. If someone transported goods regularly or as a habit, we would use the multidirectional verb wozić.

The English translation says "these goods", but ten towar looks singular. Is that right?

Yes! In Polish, towar is a singular masculine noun used collectively to mean "goods" or "merchandise". Because it is singular, it pairs with the singular word for "this", which is ten.

Is ten towar the subject of the sentence, or is it in the Accusative case?

It is in the Accusative case because it is the direct object (the thing being transported). For masculine inanimate nouns like towar, the Accusative case looks exactly the same as the Nominative (dictionary) form. The actual subject doing the action is ktoś (someone).

Why does the word for store change to sklepu?

The preposition do (to) always requires the following noun to be in the Genitive case. For the masculine noun sklep, the Genitive ending is -u, making it do sklepu.
