"I like you all."
Translation:Ich mag euch.
First, you need to know there are several different words for "you" in German:
du - for speaking to one person in a familiar tone
ihr - for speaking to multiple people in a familiar tone
Sie - for speaking to any number of people in a formal tone
These are the words you use in nominative case, i.e. for the subject of a sentence. The verb form also changes to fit with the subject, like "I am" but "you are" in English:
du bist alt
ihr seid alt
Sie sind alt
When "you" is not the subject of the sentence but rather the object, we need to use different words. This is called accusative case. This is equivalent to how we can say in English "he likes the dog" but "the dog likes him". In German, the "you"s can also change when they are the subject:
du --> dich
ihr --> euch
Sie --> Sie (this one stays the same)
As a result, you would end up with the following sentences, which you would choose between depending on how well you know the person and how many people you are saying it to:
ich mag dich
ich mag euch
ich mag Sie
So can you see why Duolingo wants euch now? Do you think there are any other possible translations for this sentence?
Later you'll also learn the third German case, dative, which modifies the words again. You can find the whole table of pronouns on Wikipedia. I recommend keeping a copy accessible in your notes until you've memorised it!
I agree. The "all" just confuses the issue. German has a different word for singular and plural "you", but English does not, though it used to ("Thou" for singular). If an English sentence including the word "you" is to be translated into German, then perhaps Duolingo could put "singular" or "plural" in brackets with the word "you", so we would know which German pronoun to use.
Yes that is also correct. However Duo often uses "you all" to simply mean second person plural "you" in which case you don't need the alle. In countries outside the US "you all" will usually have a slightly different meaning which emphasises the collective "all" and in this case you probably need the alle to achieve the same emphasis.
No, because of the cases in German. Ihr means you, yes. But whem "you" is the object of the phrase, is has to change its form. You can look at this(Keep it close to you until you memorize it) https://en.wikipedia.org/wiki/German_pronouns#Personal_pronouns . In this sentende, "you" is the object, so you have the use "euch" instead.
Ihr is for whem "you" is the thing doing the action. If you were to reverse the sentence and try to say that "You(all) like me". Them you would have "Ihr mag mich"
Several people have said that they agree with the given answer, saying that "Ich mag euch" means "I like you all". I really don't see why. Surely it just means "I like you", with "you" in the plural sense.
