About Klingon (sur le Klingon)
I started the learning of Klingon (i'm french) and i am a bit confused... is it possible to learn this! Somebody can help me? J'ai commencé à apprendre le Klingon (je suis français) et je suis confus ... est-ce possible d'apprendre cette langue! Quelqu'un peut m'aider? Est-ce qu'on peut espérer le parler?
You didn't explain why it seems so difficult to you, but I suspect you may be trying to figure out the grammar from the exercises and that is a difficult way to do it. A lot of good explanation is given in the Tips. If you have not been reading the Tips, I think you will find that they help tremendously.
If you are doing the course on iOS or Android, you cannot currently access the Tips through the app. To access the Tips, you will have to access the course using a web browser at https://www.duolingo.com/, either from your mobile device or from a computer. When you click on a Skill, it will expand to reveal a Start button and a Tips button.
If you click on the Tips button it will reveal the Tips and give you a detailed explanation of the grammar that is introduced in that Skill. If you have questions after reading the Tips for the any Skills, then please return to the forum to ask your question, explaining what you didn’t understand or what seems contradictory to you.
