orange is feminine
Why not "ein"?
Orange is feminine. Ein is for neuter and masculine, eine is for feminine
How do you pronounce 'orange'? It doesn't sound like the english way to say it.
You're right, it doesn't. I don't know a good way to spell it phonetically, but if it helps at all, in German "Orange" is a loanword from French.
Why not die for that?
It is due to a grammatical 'structure' called Nominativ and correlates to what question a certain sentence answers.
Kindly elaborate. Usually we put it as- sie isst die Orange
What is the difference between 'das' and 'dass'?
