"Můj dědeček nenávidí slabou kávu."

Translation: My grandfather hates weak coffee.

[Daku_]

Why not poor coffee? Thanks :-)

[VladaFu]

Poor is bad quality - špatnou kávu, nekvalitní kávu. Slabou kávu is weak coffee - a lot of water in it or a small amount of coffee.

[JohnBraga1]

is there a difference between nenávidět and nesnášet? Could either be used?

[Stevalion]

Nenavidet=hate

Nesnaset=can't stand

[BoneheadBass]

The meanings are very close, with nenávidět being perhaps stronger (especially, I think, when used about people). But both are accepted for this sentence.

[Translingual]

I suppose one could also call it a "long coffee".

[AgnusOinas]

Or "acqua sporca" - dirty water - špinavá voda :)
