Hallo allemaal!

July?! Now already?! Don't worry, a lot has happened in our last five months of silence!

Team Expansion!

We have an awesome new team member! Welcome TheBramnotABram!

Hey everyone, I'm the latest contributor to the tree 2.0 project and I'm excited to see it all coming together slowly. Also a big Duolingo user myself, trying to balance Spanish, German, and French, each for a totally different reason. In my daily life I'm a Bible translator, so I know a thing or two about how to say the same thing in many different ways, which is something I plan to contribute to the new tree as it is finishing up.

Also, we have found two (equally awesome) alpha testers!

Welcome pilarlagos1

Hi all, I’m an alpha tester for the Phase 2, tree 2.0 project. I’m a complete beginner in Dutch and Duolingo has definitely made the process a lot more fun. Initially, I started using Duolingo to reinforce my French classes at the Alliance Française. I’m a communications specialist by trade and a self-taught graphic designer. I’m also a language junkie (which is why I’m using Duolingo to begin with) and moved to Japan for two years to learn the language. Looking forward to contributing to the project and hopefully making progress on my journey to learn Dutch. ​Intelligibility​ not required.

and pschatten!

Howdy! Along with what Pilar said, I am also an alpha tester of the new Duolingo Dutch tree. I am a rocket scientist by day and a linguaphile by night. Over the years, I have used many different methods to study a myriad of languages and Dutch is definitely no stranger to me. In fact, I am currently using it as the primary language to learn another language. Nonetheless, I am excited to be a part of this awesome team, and feel like my meticulousness and experience in different language learning methodologies can provide for a unique contribution to testing and improving the new Duolingo Dutch tree.

Tree 2.0

It's coming. Soon™. No, jokes aside, we're still busy working on it. We have been adding more and more sentences every day, and our new team member and alpha testers already showed that they are a great part of our team. After moving some skills around, adding new ones, splitting some, merging some etc. we finally decided on our final tree design, and believe me, it’s worth the wait!

Tot de volgende update!

Week 53

1100 words, 55%. Switching to Sunday updates for now. The new projected date includes tree verification plus TTS setup tasks by others.

Lextum8 from Team EO for ES wrote 6 days ago:

Lamentamos las demoras

Duolingo ya nos ha respondido con respecto a la grabación de las oraciones, ya han iniciado todo el proceso que nos traerá la voz al curso. Lamentablemente Duolingo también está migrando su sistema de TTS/grabaciones lo que les tomará un par de semanas al menos. Mientras tanto con suerte se grabará todo y luego de esas semanas añadirán las grabaciones finalmente!

Les pedimos paciencia, ya han sido casi 10 meses y es entendible que todo el mundo esté ansioso, pero al menos ahora estamos más seguros que antes, falta muy poco :)

Slow progress

Working alone in a course allows channelized thinking and quick progress, but it is also accompanied by times of slow and non-existent progress: I'm afraid this is one of those weeks. I hope to keep the course moving to meet the 28th February deadline.


Spanish for Chinese speakers is now available in beta! WIU will get back on schedule beginning next week.

Who else is waiting for Greek!!

July 17, 2016

Thank you again for your updates. They are the main reason I make a point of logging in on Sundays now.

July 17, 2016

Arabic, Japanese and Chinese for English speakers!!

July 17, 2016

I second all three of these. Hopefully we'll have (at least one of) them in the works soon now that more courses are going into Beta.

July 18, 2016

Don't hold your breath for Japanese and Chinese. I have no idea if the current Duolingo system could handle a logographic writing system. But I hope it can! In any case, hopefully Arabic will start soon, since it is of the same language family as Hebrew (Slightly more complicated writing system though).

July 18, 2016

Kind of disappointing that there are 5 courses (Besides the manually updated ones like Swahili and the courses at 100%) that have not moved at all in the past 4 weeks. That is five course that have consistently not progressed not one week, not two, but 3+. This is out of the 22 courses currently incubating. That is 22% of all the courses are stagnant. I understand life happens, but Duolingo has felt kind of slowed down recently...

July 18, 2016

I was just looking at this saying "The leader extraordinaire is only 2%?" I suppose those weeks of one team or another getting 17% or so couldn't be expected to last. But seriously, thank you to all the contributors, we can forgive you for a slow week as long as the courses you make are awesome, which I'm sure they will be!

July 18, 2016

1198 lingots for this comment wow :O

July 18, 2016

It's an obnoxious friend who decided to lingot bomb me... Unfortunately I don't have the script for giving them fast and he does....

July 18, 2016

And DON'T YOU DARE join in. :-P

July 18, 2016

I will if you say the magic word!!!!

(The lingot giving script doesn't work anymore on the wikia, I tried it yesterday)

July 18, 2016

I will be very careful to not say the magic word, then. :-P

July 18, 2016

pretends to be A_User FINNISH!!!

July 19, 2016

Oi! :-P

July 19, 2016

Thanks for the update. Didn't Spanish for Chinese speakers get released into beta? Also, Greek re-updated their release date to the 20th of August, if it matters.

July 17, 2016

Yes, it did on 7-July. I pasted old stats initially...

Edit: Yes Spanish for Chinese.

July 17, 2016

Really? Are you possible confusing it with Spanish for Chinese?

July 17, 2016

Whoops! I did it the other way because I thought I had messed up initially. Slams head against wall.

July 17, 2016

LOL. I actually got excited and checked hoping to add it to my Spanish. :(

July 17, 2016

No one has mentioned Romanian's great progress this week, they're getting closer and closer to beta.

July 18, 2016

Sorryif this is the wrong place to ask, but is there a reason why no "from German" courses are in the works at the moment?

July 17, 2016


July 18, 2016

This is a complete guess, but it could be that German speakers tend to have good english, which makes those courses slightly less of a necessity.

July 18, 2016

Probably the lack of contributors or interest.

July 17, 2016

German for Italian speakers is in Phase 1. It's likely that its contributors will start Italian for German speakers some time after German for Italian speakers reaches Phase 3. :)

Likewise, there are contributors interested in both German and Arabic, Portuguese, Russian, or Turkish.

Now the courses teaching German for Arabic, Portuguese, Russian, and Turkish speakers have all recently graduated to Phase 3. After taking a break their contributors would probably start courses teaching Arabic, Portuguese, Russian, and Turkish for German speakers. :)

July 18, 2016

Thank you for the update :) Good to see the courses moving, especially Czech. Keep it up! I very much hope we will see some new languages in the incubator in the coming weeks.

July 17, 2016

Where is Parseltongue! I could be a contributor!! :P

July 17, 2016

Parseltongue is a poor match for Duolingo, due to the lack of a written component. Because, you know, snakes can't hold pencils. :-P

July 20, 2016

Well, I would say that snakes don't need to learn it because they are born with it and unless you were born a Parselmouth, you will never be able to speak it fluently or even understand it entirely due to its complexity. However I could help you to recognize some of the more common words and basic sentence structure so you may be able to understand bits and pieces of conversation. (But that's only if you're a pure blood of course). Maybe you have a pet snake you'd like to get to know better ? /

July 20, 2016

Most courses are releasing the second version of the tree! What about the Turkish Course?

Did you mean ES for CN? Because that sounds a little too good to be true :(

July 18, 2016

Yes, ES for CN. Corrected. Thanks.

July 18, 2016

Ya me había emocionado. Ojalá algún día podamos estudiar chino aquí en Duolingo. Sería lo máximo : )

July 18, 2016

That's why I got confused...

July 18, 2016

I just saw a 2-day-old status update at :)

July 18, 2016

Hope your travels went well, and happy to see you back!

July 17, 2016

Thanks, Danielle. One year in 10 days! :)

Then I expect your photos are going to be incredible, looking forward to seeing them :)
