I am a boy=Ich bin ein Junge You are a boy=Du bist ein Junge

Ich bin Du bist Er/sie/er ist Wir/sie sind Ihr seid

eine is a female form, and ein is a male. Also, children do not follow this rule, we use the possibly neutral ein for all children.

They explain when to use them, and some other helpful hints.

If I'm correct, just about every noun in German, proper or common, is capitalized.

you could use 'nur' to emphasise that it is a single boy. nur = only/just/solely.

so 'a boy' = ein junge. 'just/only one boy' = nur ein junge.

The emphasis may be different, but the word is "ein" in either case.

Because ein is masculine.

Normally when there's a verb, something is in accusative case, yes. The verb seine (conjugated here as ich bin) is an exception to this - both sides are in nominative case.

vong Geschlecht her.

...is that meme still going around?

You would use them just like you would in English.

Ich bin - I am

Bin ich - Am I.....?

The first one starts off a statement, and the second a question.

I am your friend - Ich bin dein Freund

Am I your friend? - Bin ich dein Freund?

Understand? :)

The word "ein" is used to indicate a singular noun the same way "a" is used in English. The sentence here doesn't mean to stress quantity, rather the fact that the speaker is a boy. When you wish to convey "I am a boy." to a German, you would say "Ich bin ein Junge."
If you wanted to say "I am only one boy" in order to stress quantity, you would say "Ich bin nur ein Junge"

Junge = "boy"
Kind = "child"

No.

junge is a boy (not an adult man, that would be mann). Kind is a child, and Mädchen is a girl.

Literally, "der Junge" can mean "the young one" as well as "the boy" – these are just two different meanings of the same, say, 'sequence of letters'. Grammatically, they behave differently, as mizinamo pointed out. And: youth = Jugend, yet another related word.

But jung means young

ich bin ein mädchen. An adult woman would be eine, but not a young girl.

Junge = "boy" (only male)
Kind = "child" (any gender)

There's no exact equivalent of "I'm" in German, but German does use some abbreviations. Often they are quite different from English ones though. Generally Duolingo does not work as well if you use abbreviations in English, so just write words out fully and you'll be fine.

No, as the other comments confirm it only means "boy".

There's no exact work for "teenager" in German, but sometimes they use the English word. Sometimes the word Jugendlicher might be used, but this is more like "youth" and isn't specific to the ages of 13-19. Junge does not have this meaning.

No. einen would be the accusative case, but with "to be", there is nominative case on both sides.

It's not grammatical and so does not have a translation.

(And there's no real way to create an English sentence with the same measure of ungrammaticalness, to give an idea.)

Ein is masculine and eine is feminine. Ein is also used for neuter words :)

Eine is strictly feminine (if I'm correct) and ein is neuter and masculine ^^

ein is masculine and neutral, while eine is feminine. In the sense of language, an object or a child is neutral, a woman is feminine, and a man is masculine. I might be wrong about the object (I know it isn't that way in spanish) but I think I'm correct.

No, you need to match the right form to the gender of the noun. Eine is only for feminine nouns. The gender of nouns just needs to be memorised when you learn them.

You should keep the meaning the same when you translate. If the sentence says "boy" then you should only write Junge, and if it says Kind you should only write "child", for example.

Your understanding is correct. Ein/eine can mean either "one" or "a". Usually "a" will sound more natural, so Duolingo prefers this translation. But it depends which answers got written into the computer program's database. Sometimes it's not perfect.

Ein is before masculine and neutral (der, das). Eine is before feminine (die).

eine is used before words that are grammatically feminine.

All words in German have a grammatical gender, not just words referring to people; and the grammatical gender of an item generally has nothing to do with the item itself.

For example, der Rock "the skirt" is grammatically masculine even though it's something usually worn by women; das Mädchen "the girl" is grammatically neuter even though girls are female; der Löffel "the spoon" is grammatically masculine even though spoons aren't alive; das Pferd is grammatically neuter even though horses are alive; die Person is grammatically feminine even though a person can be male or female; and so on.

What do you mean with a masculine verb?

Also, there is no German word madchen -- Mädchen is spelled with a capital M (it's a noun) and an ä (or if you can't type that, then write Maedchen).

Ein - masculine (Nominative) and Neuter (Nominative and Accusative)

Eine - feminine (Accusative and Nominative)

Ein is used for masculine and neuter words, whereas eine is used for feminine words c:

No. That would have to be Ich habe einen Jungen, with einen Jungen in the accusative case as the direct object of haben.

Here's how that works, it goes Ich = Bin Du = Bist Er/sie/es = ist Wir/Sie = Sind and Ihr = Seid So when you are referring to 'you' informally, you would use bist. If you use 'sind' you are saying formal you, they, or we.

"Ich" is nominative case, and "mir" is dative case.

is "ich" pronounced as "eek" or "each".

Neither.

The ch in ich is a sound which is not often used in English, but some speakers make this sound when pronouncing the "hy-" sound at the beginning of words such as "huge" or "human".

In the International Phonetic Alphabet, it's [ç].

"I am a boy" and "I'm a boy" have the same meaning in English, but Duolingo doesn't like contractions, so use the first one.
