DJGeoRob from Team Tagalog wrote a week ago:

hints on linking verbs

The linking verb "is" may be translated into Tagalog as "ay" or "ang", the latter more appropriately being translated into "is the". I did some updates on the hints, hopefully the updates would be retroactive.


AndrsBrny from Team Hungarian wrote 1 week ago:

Some more, some less

Hello everyone,

another week has passed and our error rate has gone down yet again. Not quite as much as before and we had some ups and downs, but we're below 12, at least. Franz has done a vast amount of sentence fixing this week, many of you will have received some notifications about accepted translations, we hope! There are also some additional tips & notes towards the end of the tree and more are coming soon!

Summary (tl;dr)

Moving ahead with a lower error rate, many fixes this week, and some new tips & notes! Thanks once again for your help!

안녕하세요 여러분!

We're hard at work on the skills Written/해라체, Past Tense, and Sino-Korean Numbers.

We also now have Tips in place for the first 18 skills.


Increased overall progress. Today's report covered a little over 8 days as well. That might be a contributing factor as well.

Thx for this update jitengore!

I find it sad that Duo doesn't allow basic tables in forums...
Here screenshots of what it would render (I find it easier to read ;) ):


  • black \& non-italic = team's own computation/estimation
  • gray \& italic = Duo's (flawed) automatic computation/estimation

Sorted by estimated %age of completion

Sorted by estimated launch date

October 25, 2016

Wow. Forgive me geeking out over a spreadsheet, but that is a thing of beauty. Much easier to read (which is not meant to take anything away from jitengore for all the hard work on these updates).

October 25, 2016

Thank you. I love the spreadsheet

October 25, 2016

Does it behoove me to add to the growing dissent regarding the Yiddish course' progress? Or have we moved on?

Dear underwood jones, and community,
I apologize for my long diatribe, that I have now removed, and some of the comments I have made. I am re-dressing them now.
and will also take a bit of a rest from duo..

Please note, I have edited my comments and put this in their place. I do not mean to cause upset in this community I value.
With my kind regards, Linda

October 26, 2016

I think they were just playing on the fact that the Yiddish contributors pretty much abandoned the course and don't want anyone else to contribute to it. There have been a lot of people talking about it lately.

October 26, 2016

Wow. Just wow.

SO LONG! How long did it take you to write this?

October 26, 2016

...does anyone feel like there's a surge of down voting on Duolingo lately? I can (unfortunately) expect some hate with my Esperanto fandom, but I've seen really benign/positive comments like "I'm excited to improve my Spanish this week!" get downvoted. I love the WIU because of its overall positivity, kinda strange to see it here

October 25, 2016

People probably downvote topics such as "I'm excited to improve my Spanish" because they feel it doesn't contribute to much discussion, but I still think it's better than the countless "hello" topics.

October 25, 2016

It was actually on a thread where the whole point was to post a weekly goal, everyone should share their language and their target daily points. Some people were upvoted and others downvoted in spite of the fact that everyone was posting the same general idea. I'd seen another complaint from a user who found his/her topics were always downvoted, all in the past week, which makes me wonder since i didn't notice much of this in the past ( or not to this degree)

Thanks for this great update once again Jitengore.
The amount of work you do for this global community of language learners is phenomenal.

And this report is only some of what you do that I am aware of.

You are amazing and greatly appreciated by ever so many of us !

Also a shout out there to ALL of you - in whatever capacity you are supporting our Language Learning community.

Both those in the incubator - in the teams.
Those in the Duolingo forums, that patiently and kindly answer and assist others to use this platform for Language Learning.
Those younger members who are with us - that choose to NOT post spam and off topic discussion in our forums, whose prime purpose is for Language Learning related issues. And choose to show kindness to others.

And also the amazing team of staff behind the scenes, that labor away behind the scenes, maintaining this platform, and improving it, in a multitude of ways.

To all of you - Thank you.

Is it really possible for English-for-Tagalog to release on December 24, 2016? That seems so fast. Maraming salamat!

October 25, 2016

They are working extremely fast compared to most other courses

October 25, 2016

I will be pleased with any release date. I'm just happy that they started work on the course. A year ago I started teaching myself Tagalog. I'm making progress but it's slower than I'd like. I miss the Duolingo method because it makes learning so fast and easy. I'm learning by talking with native speakers, lessons on YouTube, and Google Translator. It's a fun way to learn.

October 27, 2016

They'd have to be doing about 9% per week, with 9 weeks and 84% to go.

October 27, 2016

There is also the matter of the tree validation and other post-processing after the team pulls the trigger.

October 27, 2016

Although they probably wouldn't have to record audio. That's usually the thing that keeps at the 100% mark for weeks or even months before being released.

October 28, 2016

is it just me, or have more estimated dates been added?

October 25, 2016

Ah so sad, I just came here from a post dated two years ago saying Chinese for english was about a third done... I guess that project died?

Still, thanks for sharing - just as good to know what is not going to happen as what is :)

Congrats and thanks on all the great work!

October 25, 2016

Are you sure it wasn't talking about the English for Chinese speakers course?

October 25, 2016

Ah sorry ComradeFrancis I didn't save the link... probably my mistake. :)

October 26, 2016

There's never been a course teaching Chinese in the works on least not publicly. See

October 25, 2016

Good to know annika_a :) I've only just started out with french, but it'll be my next goal as mandarin is probably the second language where I live and it'd be quite helpful. I understand it's not possible to support every language... I'm just enjoying duolingo too much lol

October 26, 2016

I know what you mean... Meanwhile, the Duolingo community has collected a list of other language resources for Chinese which are already available:

October 26, 2016

Thanks a lot for that - bookmarked :D

Dear bobbyfetta,
I am so pleased to hear you are really enjoying the course you are doing here.
As has been mentioned by annika_a , we have not as yet had a course even enter the incubator for learning Chinese for English speakers. So this is not a case of delay in 'release'. As this reverse course has not yet been able to enter Stage 1.

However we do have the reverse course for Learning English for Chinese. You can check out the courses for Chinese speakers here.

I do assure you from all that I know of Duolingo, that they will be keen to also do the reverse course. However it is not as simple as just doing it.
Currently there are 23 courses in Stage 1 development.
7 in Stage 2 - Beta release,
And an amazing 57 in Stage 3. Even those in stage 3 require constant modification, support and development.

In all I see of Duolingo, it has no intention of stopping there. However to maintain currently what there is also requires enormous resources to be deployed - beyond that even of the volunteer army that has made all this possible. Please note - I am not privy to the inner workings of Duolingo. I am making these comments based on my experience working with computer programs and companies. This is not an official statement from Duolingo. This is me commenting - in my opinion.

Back to the details of the Chinese course, there are some unique features of the Chinese language, that will no doubt need to be addressed before it can even enter into the the suite of courses that are provided, I would imagine, based only on my opinion. And these unique features will also lead for a slower development to some of the other courses - which share greater commonality between them.

Thanks though for showing your considerable interest in wishing for this course also. For this is also I dream I will celebrate when I see it starting to become a reality.

October 26, 2016

As has been pointed out before on other threads, the 23/7 is far from what we've seen at best. The 57 is obviously a record as courses don't go backwards.

October 26, 2016

Yah, as all have said, that was the English for Chinese speakers course. The main issue with the reverse course is characters, but trust me, once Duolingo gives us the okay the contributors (me included) will be excited to start it.
