"Ett tak"

Translation: A roof

[draugur_ulv]

isn't the "ceiling" the same word?

[Zmrzlina]

It is.

[Jan-Olav]

If you need to specify you can use 'innertak' for ceiling and 'yttertak' for roof.

[draugur_ulv]

it didn't suggest it as an "another correct answer".
I guess I'll report "my answer should be accepted" next time I get this sentence...

[JANBOEVINK]

I heard: -ett tag-. Very similar!

[ChloKokx]

I heard etakl!

[Solo_BUNI]

What about... Tack!...

[myriam365]

Etok.

[kiomarv7]

Very similar to the German "Dach."

[Meathur]

And the Dutch 'Dak'

[JoseeV64]

But the Dutch "tak" is a branch of a tree. It's a false friend.

[JANBOEVINK]

In this case the Swedish neuter should help: -het dak- en -de tak-

[devalanteriel]

Yes, we call that gren or kvist in Swedish. The Dutch word is related to e.g. English "tack" and German "Zacke".

Cognate with thatch. I’m going to remember it now!
