Why is the "J" in "Junge" capitalised here even though it's in the middle of a sentence? Are all nouns capitalised in German?
Yes, all nouns are capitalised in German.
That information is one of the first things in the tips and notes for the first unit on this course, so I'm guessing you may not know about the tips and notes which explain German grammar.
They're not available to most users of mobile apps, which is why I would not recommend using mobile apps for learning a language on Duolingo (though they can be useful for revision).
On the Duolingo website https://www.duolingo.com/ , you can access the tips and notes for a unit by selecting the unit and then clicking on the light bulb next to the 'Start' button:
If you don't see the light bulb on a small screen (such as a mobile), you could try requesting the Desktop view of the website; if that doesn't work, you may have to use the website on a larger screen (such as a tablet or laptop computer).
Thanks so much! Yes, I use the app on my phone, and have never seen that lightbulb icon. I wonder why they left it out on the mobile app. Unfortunately, it's not possible for me to use a computer or similar device right now, so I'm stuck with the phone, although it seems that using the site on the phone instead of the app reveals the lightbulb. How do I request the desktop view for the app? Do I request it on Google play? I have requested some other changes there before, like including cyrillic keyboards for people who can't access other languages on their keyboards (mine can only harbour 5 languages and I already have 5 languages set on it for regular use, so I could use a keyboard provided in the course) and courses for some new languages. Sorry if my question is a stupid one and thanks :)
"request desktop view" is something that some browsers (e.g. Safari, Chrome, Firefox) provide when viewing a website that behaves differently when it thinks it's being accessed by a mobile device compared to a desktop.
It's not something you can do from within the mobile app; it's only applicable to opening the website on a browser on your device.
It is accessible from your chrome browser. Just click on 3 dots that are on the top right corner, then you scroll down till you see "request desktop view". Just click on it and you are good to go..
Oh wow, in Age Of Empires 3, the German explorer says "wichtig" when you tell him to go somewhere. Awesome!
Nearly. It is ein Junge in German -- capitalised, because it's a noun, and all nouns are capitalised in German.
Junge = boy. That is, a male child.
"kid" or "child" is a young person but could be male (= boy) or female (= girl).
but doesn't 'knabe' also mean boy? what is the difference between knabe and junge?
Knabe is also used to mean "boy", especially in the south and, I believe, in Austria.
This course considers it a regionalism.
So use Junge here, which we use as the standard German word for a boy.
I'm noticing that 'Mann' and 'Junge' is capitalized, does German have different punctuation rules for capitalization?
All nouns are capitalised in German.
This is mentioned into the tips and notes for the very first unit -- if you did not know this, perhaps you don't know about the tips and notes? If so, you're missing out on a lot of grammar exaplanations.
They are currently not available to most users of mobile apps, so I would recommend using the website https://www.duolingo.com/ .
The tips and notes "hide" behind a lightbulb in the little window that pops up after you have chosen a unit:
Where to use ein and eine ?
Use ein before nouns that are grammatically masculine or neuter.
Use eine before nouns that are grammatically feminine.
The grammatical gender of a noun is simply something you have to memorise; eine Person, for example, is feminine even though a person can be male; ein Mädchen is neuter even though girls are female; and ein Löffel is masculine even though spoons are neither male nor female.
