"We want to see the potato!"
Translation:Wir möchten die Kartoffel sehen!
lol, you know potato is Germany's national cuisine. in addition to that, during WWII, aproximately 24 tons of potato was made into 5.6 tons of Ethyl Alcohol which was then used to fuel a V2 rocket (the first ballistic missle ever). That's why dass du immer die Kartoffel sehen möchtest, oder?
Native is defined as someone who was able to improvise a whole grammatical (a.k.a.: "correct") sentence by the age of 5. It doesn't matter how good or bad you are with the language or how much experience you have with it. Actually it's not rare for native migrant speakers to not be able to use the whole language because of their life circumstances (in such cases, we say that they are heritage speakers). What matters is the naturalness of the language: A native speaker has an unconscious intuition, but the L2 speaker (the one who learned it after 5) is fully conscious and does not know how to react to situations outside of what he knows.
Möchten is a verb from derived from the modal verb mögen, namely the Konjunktiv II, but used with present meaning.
The modal verb in its infinitive form mögen generally means “to like” and this is the meaning you express if you conjugate it with a -g- in its root (mag). However, the conjugation with -chte (möchte) means “to want/would like”.
The explanation is similar in English: “liking something” doesn’t mean you “want” it. But used with the modal verb “would” (corresponding to Konjunktiv II in German), i.e. saying “you would like something”, this is a polite way to express that you want something.
The last important thing you must know is that the conjugation with -g- (mag/mög-) normally is combined with a noun while the conjugation with -cht- (möchte) can be combined both with a noun and a verb.
If you wonder how we express in German that you “like doing something”, we use the adverb gern(e) after the conjugated verb.
Why was wollen unacceptable?
Because wollen only means "want", not "We want to see the potato!". You'll have to write more words than just that.
If you have a screenshot that shows the exercise you had, your full answer, and perhaps also Duolingo's reaction, then show it to us, please -- upload it to a website somewhere (e.g. imgur) and tell us the URL of the image.
In any event, please always let us know your entire answer if you want helpful responses.
Perhaps you mis-spelled some other word (e.g. Kartofell instead of Kartoffel)? Perhaps your word order is wrong (e.g. Wir wollen sehen die Kartoffel)? Perhaps you used the wrong gender (e.g. Wir wollen den Kartoffel sehen)?
It's impossible to tell if all you'll divulge is that you used wollen (which is part of several accepted translations).
