Teller is singular and plural?
Yes. You must rely on articles, prepositions, verbs, context, etc to determine if it is actually singular or plural (just like similar English words).
but there was no article [translate he has plates], and die Teller wasn't an option? And Tellern wasn't accepted, so - I'm confused. Is it just the absence of EIN that makes the word Teller plural? If so - when and how is Tellern used?
Why not "Tellern" as suggested and as I found as the plural of "Teller" in my German dictionary?
The plural of »Teller« is only »Tellern« in the dative:
der Teller nominative
des Tellers genitive
dem Teller dative
den Teller accusative
die Teller nominative
der Teller genitive
den Tellern dative
die Teller accusative
Why is "Er hat die Teller" wrong?
That'd be "He has the plates".
We Wanted to show to the program, that we know : die Teller - PLATES !!!!
hey, Sie haben einen slowakischen Namen, schön.
I typed "Er hat Platten." It says I am wrong.
Because «Platte« means “platter” — a large flat serving dish.
...weil Platten keine Übersetzung des 'plates' ist... Platten wären flache große Teller, die man in die Mitte des Tisches stellt oder auch Bodenbelag könnte damit gemeint werden.
Hello? We're beginners here.
me too - google translate thinks this is correct
Teller is not one of the choices.
So, it is "Er hat einen Teller" for one plate, and "Er hat Teller" for many plates. Is that correct?
