Questions & Answers about Goście są teraz w restauracji.
How do we form the plural goście from the singular gość?
Gość (guest) is a masculine personal (virile) noun. Because its stem already ends in a soft sound (-ść), we simply add the ending -e to make it plural, giving us goście.
Since goście is a masculine personal (virile) noun, does it mean all the guests are men?
Not necessarily! In Polish, the virile plural form is used for groups consisting only of men, but also for mixed groups of men and women. You use goście as long as there is at least one man in the group, or if the specific genders of the guests are unknown.
Why does the word for restaurant change to restauracji here?
We are describing a location, so the preposition w (in) forces the noun into the Locative case. For feminine nouns ending in -cja, like restauracja, the ending changes to -cji in the Locative.
Is it okay to put teraz (now) at the end of the sentence instead?
Yes, Polish word order is very flexible. You could say Goście są w restauracji teraz and be perfectly understood, but placing time words like teraz right after the verb usually feels a bit more natural and neutral.
