Forming location nouns (-nia, -isko)

Places of Business and Rooms: The "-nia" Suffix

Polish frequently creates nouns for specific places—known grammatically as nomina loci—by adding suffixes to existing words. The feminine suffix -nia (and its variant -alnia) is extremely common for naming shops, parlors, and designated rooms.

This suffix can attach to nouns (like cukier for sugar, forming cukiernia) or verbs (like przymierzać for to try on, forming przymierzalnia).

This patisserie is located between the school and the park.
Ta cukiernia znajduje się między szkołą a parkiem.
Is the fitting room occupied now?
Czy przymierzalnia jest teraz zajęta?

Because they end in -a, these location nouns behave like standard feminine nouns. Notice how they end in -i or -ni when shifted into the Genitive or Locative cases.

You must buy a cake in this patisserie.
Musisz kupić ciasto w tej cukierni.
The children want to go to the ice cream parlor.
Dzieci chcą iść do lodziarni.
You can smoke only in the smoking room.
Możesz palić tylko w palarni.

Open Spaces and Grounds: The "-isko" Suffix

To denote open areas, fields, or larger public facilities, Polish typically uses the neuter suffix -isko (or its variant -owisko).

But they closed this sports field yesterday.
Przecież wczoraj zamknęli to boisko.
In winter we gladly go to the ice rink.
Zimą chętnie chodzimy na lodowisko.

As standard neuter nouns ending in -ko, these words take the ending -u in the Locative case (for example, na boisku or w uzdrowisku).

The boys always meet on the sports field.
Chłopcy zawsze spotykają się na boisku.
One can rest well in this health resort.
W tym uzdrowisku można dobrze odpocząć.
People buy fresh fruit at the marketplace.
Ludzie kupują świeże owoce na targowisku.
