Why hasn't it taught me this?
How come this app doesn't teach me stuff like how to ask if someone speaks english? or to say I don't speak the language very well?
Duolingo is not designed to teach "Tourist Language." If that is a primary goal for you, consider buying one of the small phrase-books which also have pronunciation guides. In German (as you know), as well as other languages, more than one word is used to express "you" according to whom you are addressing. And, that word may change it's form depending upon it's use in a sentence, i.e., subject, direct object, indirect object. Indicating that one "doesn't ...." or one "can't ....," involves learning how to express a negative, and that can also become complicated dependent upon the language being studied. Acquiring knowledge of how another language "works" is much different from learning phrases to assist one in "surviving" when visiting another country. Duolingo can help with the first, a phrase-book is of more help with the latter -- you can always point to words, or perhaps a picture, in a phrase-book to help get your message across.
In Duolingo you will find the explanations in the grammar "Tips and notes" in the "Desktop mode" of the browser of your phone/tablet/Pc.
- go to www.duolingo.com
- in the Firefox or Chrome browser you can select the "Desktop mode" via the three dots in the upper right corner of the screen.
(Note: In some iOS phones with a small screen, "Desktop mode" is not available)
- just click on the Skill and scroll to the bottom of the Lessons page.
