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 & Notes. If you have not been reading the Tips & Notes, 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 & Notes through the app. To access the Tips & Notes, 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 light bulb.
If you click on the light bulb it will reveal the Tips & Notes and give you a detailed explanation of the grammar that is introduced in that Skill. If you have questions after reading the Tips & Notes for the previous and current Skills, then please return to the forum to ask your question, explaining what you didn’t understand or what seems contradictory to you.
