"Drzwi są zamknięte."

Translation: The door is closed.

[Kulink]

If this is a single door, why są instead of jest?

[Jellei]

"Drzwi" is pluralia tantum. It doesn't have a singular version, even if you literally mention "one door" it will be "jedne drzwi" - yeah, we just made the numeral 'one' into plural.

[Miknairb]

Then, do you depend on the ending of the adjectives to determine if it is just one door (the door) or more than one doors?

[immery]

no. adjectives have to match the noun so they are already plural even if there is only one door. 99% of sentences number of doors is left amibigous. only if you actually add numeral/ quantifier you can determine how many doors are there

[Miknairb]

That's very interesting. Thank you so much for your input. I wish Polish Duo had some sort of comments/instructions per each topic instead of letting all the learners swim in the deep ocean by themselves !

Kind of like the English word "pants?"

[Jellei]

Yes :)

[dambied]

Hold the door!

[Mostlaszlo]

Hodor!

How would you say "the doors are locked?"

[Jellei]

Generally the same, but if the difference between 'locked' and 'closed' is really important to you, you can add "na klucz".

[RobinB896941]

Ha! "The door's closed" "missed a space" ;)

[Jellei]

Well, I don't think that surprises you anymore, right? ;) Added now.

[RobinB896941]

I'm only surprised that there are any left for me to find ;)

"y2 and "e" sound exactly the same at the end of words; it seemsjust gyesswork to know which to use . Is there any helpful rule?

[Kristine466318]

If you are talking about adjectives that end in "y" or "e", like zamknięty, zamknięte, the rules are rather simple: y is for masculine singular. Pokój jest zamknięty - the room is closed. "E" is for plural or neutral. Drzwi są zamknięte (pl). Door is closed. Okno jest zamknięte (neutr.). Window is closed.
