"Jag tycker om starkt kaffe."

Translation: I like strong coffee.

[pekarekr]

Starkt Kaffe = Svensk Bränsle (Swedish fuel)

[Jeanbean425734]

Hahaha! I love that! So true!

[RAlberdi]

Why the definite adjective starkt?

[HelenCarlsson]

It's not the definite, it's the -t form used with neuter nouns:

ett starkt kaffe - det starka kaffet

[RAlberdi]

Ah, I always step on the same trap: ett kaffe / en kopp kaffe...

Tack for förklaringen

[zziHWP]

is it usual to say svartt kaffe as well?

[gerdlindstrm]

Yes svart kaffe, with only one T. You never write "svartt".
