"Jeho dům má fialové dveře."

Translation: His house has a purple door.

[ion1122]

Can the Czech sentence also mean "His house has purple doors"? In other words, no difference between singular and plural?

Yes, you can use this sentence as singular or plural. Jeho dům má ...

• Jedny dveře. = One door.

• Dvoje dveře. = Two doors.

• Troje dveře. = Three doors.

[endless_sleeper]

Dveře is a plural-only noun.

Hi, with reference to ion1122's question, how would you specify you were definitely asking about more than one door but did not know how many? Would you ask something like "Je vsechné jeho dveře fialové"? (hope I've got that right, had to look up "all")

[tatka_]

You can say with house context "Jsou všechny jeho dveře fialové?" or without context "Jsou všechny dveře domu fialové?"
je = singular
jsou = plural

That is very helpful thanks.
