"I do not eat the potato because it is not good."

Translation: Nu mănânc cartoful din cauză că nu e bun.

[Coriander18]

Is the 'din' optional?

[Luchtmens]

No, it's mandatory.

din cauză că = because, as

[Mike176398]

What is wrong with fiindca for because in this case?

[186.Eb4to1LJgnhF]

You can use interchangeably: din cauză că, pentru că, fiindcă, deoarece, and a few others.

[Mike176398]

Except, Duolingo still marks it as wrong.

[186.Eb4to1LJgnhF]

And will do so till the end of time.

[Pat733327]

I put " Eu nu mananc cartofel din cauza ca nu este bun" and it was marked wrong. What is wrong with it?

[Berila130]

cartofel?

[Pat733327]

Why is "eu nu mananc " wrong?

[CarloGamag1]

Why nu este bun is not accepted? Also I wrote eu nu...
Please explain .Îti voi fi foarte recunoscator!

[Berila130]

nu este bun = nu e bun
nu mananc = eu nu mananc

[CarloGamag1]

I lookcked at the sentence again and I think Duo rejected becauseI thought that potato is feminine like in all the other latin derived; la patata, la papa, a batata, la pomme de terre. This beg the question why is Romenian different?

[Berila130]

I think papa, patata, batata are all related, while "cartof" may be from another family ;)
However, if you want the potato to be feminine you can use the word "barabulă".
O barabulă - două barabuli. Don't expect Duo to have heard of it though... ;))
