Why einen ? Isn't Hund masculine ?
Hund is masculine. That's why it's einen.
why is sieht used and not siehst?
I said it correctly
Why "the girl is seeing a dog" isn't accepted? is it because it's not how it's said in English? English is not my native language but I thought that phrase would be also correct.
"Is seeing" is usually used in English when you are unofficially dating someone, such as "Alice is seeing Paul". You wouldn't use it this way.
I wrote the exact words in German and program would not accept it
I thought Madchen meant girl and Mädchen meant girls, but this says otherwise. What's the difference between the two? And how can we hear the difference?
Das Mädchen = girl
Die Mädchen = girls
