This is the 15833rd most frequent Polish word.
s膮
It seems there is a typo in the word "s膮." The correct Polish word might be "są," which means "are" in English.
The word 'są' functions as the third-person plural form of the verb 'to be' (być) in present tense, indicating the existence or state of a group of subjects.
Są tutaj, aby się uczyć.
They are here to learn.
In this sentence, 'są' is again the verb 'to be' but used existentially to describe the presence of objects in a specific location.
Na stole są książki.
There are books on the table.
Here, 'są' functions as the verb 'to be' connecting the subject 'te rzeczy' (these things) to the predicate 'bardzo interesujące' (very interesting), describing their quality.
