"Die schwarze Katze liegt auf dem Gras."

Translation: The black cat is lying on the grass.

I thought "the black cat is laying on the grass" would be acceptable

[mizinamo]

It's not, though. To lay is to put something somewhere; to lie is to be somewhere. Duo maintains this distinction, though many native speakers do not.

[gangsterGenes]

I put lies in the grass and it was marked wrong. that would be more common in english.

[stepintime]

"Die Katze liegt im Gras" would be more common in German as well.

[Abendbrot]

I think it concern of the height of the grass. For 2 inch high grass I am for "auf", while for 10 inch high grass "in" works well.

"The black cat lies in the grass" is marked as wrong here, but it would be a better translation. The German sentence is also wrong. Human intervention is needed here, to fix what an algorithm can't do.

[RRReinart]

Is "The black cat lies upon the grass." not quite an accurate translation?

[SharonNaor]

General question-
Does Gras also used for marijuana same as in English?

[mizinamo]

Yes.

(But we don't use Unkraut "weed" for marijuana.)
