Weekly Incubator Update: Tracking Progress from March 13th to March 20th

Seemingly slow progress
With the overall average progress under one for the last few weeks, it seems that things have slowed down in the Incubator land. However, we should keep in mind that the work done on the four courses showing at 100% is not being accounted for in this number.

Russian for English graduates from beta
The Russian for English course has graduated from beta! A well deserved congratulations to the course team and team Duolingo!

Errata: German for French course too graduated from beta! Congratulations to the course team and team Duolingo! And thanks to lizsue & scarcerer for the reminder.

A Giant Leap Forward!

Hello everyone!

After weeks upon weeks of looking to solve one of our concerns (adding notes to lessons), I am pleased to announce that duolingo user dragostis has joined our team, and he will be helping with the notes and tips that will help you in mastering the Romanian language.
We have pulled off a lot of work this week, and we plan to keep on increasing our efforts to the best of our abilities.

Below are some stats

1) We are at 1777 completed words
2) We have 98/101 completed word images
3) About 6 Lessons completed since last update

Notice - if you did not know, there is a forum page where you can ask us any questions here!

Mid-week update

I promised more frequent updates, so here we go. You might have noticed that our completion date has moved into the future again. It has changed quite a bit over time, so don't take it too seriously — when there are no words which lack sentences, the date shows the current day, but since we're currently editing the tree a bit again, the date has moved to the future.

The reason for the current edits is the following. When the original team set out to build this course, they did it from scratch! This means, they did not adapt another language's course tree, but they decided to go ahead and design a completely new course structure for Hungarian, develop and add all the skills and all the words that you'll soon be learning! Needless to say, this is a massive task. Over time, many people had to focus on other aspects of their lives again and so the group's membership changed, and changed again. When I joined in 2014, the structure of the tree was there, but it wasn't complete. Around autumn 2015, we managed to fill up all the skills with sentences.

But as far as I can tell, the structure has never undergone any revisions, and well, with a project of this scale, a few things were missing from the original tree, or came late very late in the course. So when we were waiting to hear back about how to proceed with audio a couple of weeks ago, we thought we'd use the time to improve on some of these things. And this is what we're currently doing, and what this and the next few updates will be about.

First, you might know that Hungarian has two so-called ”conjugations”: the form of the verb doesn't just vary with the subject's person and number, as in English to some degree: I walk vs. she walks. In Hungarian, the object plays a role as well: én látok egy asztalt ‘I see a table’ vs. én látom az asztalt ‘I see the table'.

To learn this, you have to be familiar with different verb forms and with accusative case, but it's a very important part of the language, as sentences of the form Subject-Verb-Object are, unsurprisingly, fairly common. In the original tree, these skills came very late — now, we've moved them to much earlier in the course, so you can actually go and say things like I love lángos early on (who doesn't?). It's a tricky thing to learn, but judging from how keen you are, it'll be a piece of süti!

Second, woolfool has combed through the course to find words that are missing (not an easy task!), and he's been very active with adding useful expressions like holnap ‘tomorrow’, ma ‘today’, weekdays, months, etc. I think you'll agree that it's good to learn these, too!

Finally, a week ago the course didn't include the past tense — now it does! Moving accusatives and the conjugations to an earlier point in the course freed up some resources later on, and so we decided to add the past tense, too. Somewhat surprisingly, tenses are fairly straightforward in Hungarian, so learning the past tense won't drive you crazy (but you'll be able to tell people about that great lángos you had last night!).

This sounds like a lot — and it is, in a way, but we're well underway with this because it's been going on for a couple of weeks. I hope you'll agree that the additional wait will have been worth it!

Summary (tl;dr)

We've started slightly reorganising and modifying the course tree a couple of weeks ago: moving the accusative and definite conjugations skills, adding lots of useful words, and adding the past tense. We're making good progress with this, and we're pretty sure you'll benefit from these final improvements before beta!

And Team Hungarian, that makes you the winner of this week's Star Update Award - that is two weeks in a row!

SebastianMolin from Team Romanian added yesterday:

Another Great Week!


This has been another productive week on our end, with finishing notes for up to the first checkpoint and more sentences being added to skills.


  • We are at 1843 completed words
  • We have images for 104 words
  • Around 13 skills have notes notes
  • We've completed a lesson this week
  • Two new Alpha Testers are on board thanks to duolingo officially making alpha testing part of the course building process. oxq and davidvdb

Croesus1983B from Team Korean wrote 13 hours ago:


Greetings all!

We on the Korean Team spent most of this past week reorganizing our tree. Now that the Incubator allows for concatenation, we have decided to change the way we approach a number of skills. These changes, we hope, will help make the learning experience more enjoyable.

We are sad to say that we lost a contributor this week. No, oree94 didn’t pass away; he’s just moving on to other things. oree94 has contributed countless hours to developing both the EN for KR course and the KR for EN course. The whole team was very sad to see him go.

On the bright side, we now have a new contributor, Jaeseop!

Week 37

780 words, 39.0%, same set of skills in progress as last week.

AndrsBrny from Team Hungarian wrote again 3 hours ago:


Hello everyone,

here's a little update on our progress for the second half of this week. One of the past tense skills is nearly done, one more to go. Given the current pace, that one should be done in a week or so, too.

We'll have to add further sentences to some of the new words like holnap ‘tomorrow’, ma ’today’, etc. — and then there'll be further continuous tweaks during beta!

Once again I'd like to thank everyone for your patience and your encouragements! We can't wait to get into beta either..!

Vietnamese, Greek and Hebrew! Go! Go! Go! I can see them coming through the door into Beta!

March 20, 2016

I'm waiting for Greek, Hebrew, and Hindi. They're all coming this year, so excited! Though I would like Arabic on here as well, that may not be for some time.

March 25, 2016

*smell. Unless you have my luck and caught a cold too. :P

March 20, 2016

What? XD I have never heard "Smell them coming through the door" although smelling something in anticipation is not uncommon.

March 21, 2016

I thought you were a dog. ( ・ิω・ิ)

March 21, 2016

Eastern Europe is on fire this week! Looking through the updates...Romanian, Hungarian, Romanian, Czech, Hungarian... So excited!

March 20, 2016

*Central Europe :)

March 21, 2016

wondering why this is being downvoted, isnt it true?

March 23, 2016

Well, It might be because of the fact the the naming of these territories is disputed.

On some maps, you will find Romania, Hungary, and Czech Republic listed as "Central European" countries, on other maps, you will find them listed as Eastern European countries, and on others, you will find them separated and listed in different territories.
Some sources call countries that are in the borders of the former Austro-Hungarian Empire as Central European, some call former Soviet states as "Eastern" and the rest central and western.
The list could go on forever, however in most cases, people tend to call them either Eastern or Central, but never both.

However if you ask the majority, they will tell you Hungary and Czech Republic are central European, while Romania is Eastern European, others will tell you Romania is southeastern European ;-)

NATO goes as far to call Romania South-East Central Europe :D

Here is an image that calls them all central Europe


In this other one, all Eastern Europe is labeled pink


As you can see, a pretty disputed field :-)

That's probably why it was down-voted ...

March 23, 2016

pretty interesting, thank you for this explanation! :)

March 23, 2016

Well it's even more difficult. After 3 years of my BA study where we've had a lot of lectures on this topic we've came to the conclusion that something like Central Europe definitely exists, but no one really knows what it is :) I mean there are numerous different definitions. The problem is that there are no natual borders and state borders in this part of Europe changed so many times especially in the last century that you can't draw any exact map. Usually areas of former Austria-Hungary plus Poland are considered to be the core of Central Europe (generally nowadays the Czech republic, Poland, Slovakia, Hungary and Austria, eventually Slovenia), but can you imagine history of those countries without Germany or German cultural influence? And what about Croatia, Serbia, Romania or Ukraine which also used to be (at least their significant parts including cities like Zagreb, Novi Sad, Cluj, Lviv etc.) part of Austro-Hungarian Empire? Or what about Lithuania which was for a long time in union with Poland? Or Latvia and Estonia with their connection to hanseatic league and German cultural heritage? Or the city of Kant Kaliningrad (Königsberg) which was German for centuries and now it belongs to Russia.

I personally don't really care about how's the region called, but my point with former comment was that generally especially in V4 countries (including my native Czech repubic) people don't like to be called Eastern Europe and they don't consider themselves to be East Europeans. because they connect it mostly with former USSR (Ukraine, Belarus and further to the east). Romania is on the other hand from our point of view more Balkans than Eastern Europe.

March 24, 2016

I'm dying for Hebrew!

March 20, 2016

Hmm no Tagalog, I guess it will appear in the future.

March 20, 2016

This guy didn't continue after the first post :/

March 20, 2016

What are these two updates per week from some of the teams? I like this. lol

March 20, 2016

Ikr :D

March 20, 2016

Teams have their own pages that they post updates to. If a team happens to post more than one update throughout the week, all the updates since the last Weekly Incubator Update will be included.

March 21, 2016

Yes, Romanian's coming close to beta, I can't wait!

March 20, 2016

Romanian is the language I am excited for :D

March 20, 2016

Cum zasi tu, asa-s hie.

March 20, 2016

It would really be funny for them to learn to speak like this instead of the literary language!

March 21, 2016

Eh, they'll pick it up in no time.

March 22, 2016

Hahaha, that's dialectal ;-)

March 22, 2016

Vietnamese and Greek!!! GO, GO, GO

March 20, 2016

Two more weeks...

March 20, 2016

Two more weeks to such beauty.

March 21, 2016

Can't wait for Guarani...

March 20, 2016

Any word on Hindi, jitengore? According to the updates, the revised tree design was to be settled on quite a while ago, and we haven't heard anything since. Also the progress seems to have stalled for months and months...

March 21, 2016

I think you're just going to have to be patient.

Doing a course from English where you build the tree for the language appears to be a much greater challenge than doing English for * speakers, where the English tree is already built. We've seen this already with numerous courses such as Russian, Turkish, Polish, and now Hungarian, Greek and Vietnamese which all took, or are nearing completion after taking, a long time. But these courses all turned out to be excellent courses as well.

March 21, 2016

You are right. Hindi course is also taking a long time like Russian and Polish courses have taken. I hope it will be excellent and awesome like them. But wait is killing me.

March 21, 2016

Yes, I'm aware of the challenges of building the course, and I'm aware it will take a while, I'm just after more information from the team since there has been a lack of follow-ups on the info provided, specifically the revised tree design.

March 22, 2016

Thanks for your patience. There will be followup soon.

March 27, 2016

Great! I'm looking forward to Greek!

March 20, 2016

I am really looking forward to Vietnamese and Hungarian!

March 20, 2016

Vietnamese, Guarani, Hindi and Swahili

I wait for you.

Seriously, what happened to Hindi? It has been stalled for months

March 21, 2016

Good job team Hungarian! I really am so excited to make friends with an Uralic language!

March 21, 2016

Let's hope we can make that plural one day! :-)

March 21, 2016

obligatory alfmf :D

March 21, 2016

alfalfmf :)

March 21, 2016

alfalfalfmf :-)

March 21, 2016

alfalfalfalfmf :D

March 22, 2016

Great to see Indonesian making progress!

March 21, 2016

It looks like they had to take the time to sort out what goes where just like team Klingon.

That said, surely we should see some progress from team Klingon in the past 4-5 months instead of being stuck at 21.8%.

March 22, 2016

They have set a new course release date for August and added a couple of new contributors, so there should be progress soon..

March 23, 2016

Old news friend, I've known about the new contributers for about a month now, and when I press loghaD for information it's pretty much always "expect to see progress soon" and "you should see some progress", and nothing seems to happen.

There's also a theory that says that the 21% hasn't changed because of a glitch in the system, but nobody has any Idea what that glitch might be.

So yeah, nobody has any idea why we can't see any progress.

March 23, 2016

Fair enough about the relative silence from the moderators, but I doubt that there is a glitch in the system. LoghaD has said that the course is coming out to beta no later than August so they have a few months of time to keep their word. I believe that this is doable. The German for Arabic team had a slow patch in their development, but completed the majority of the course in just a couple of months. I would hold on just a bit longer.

March 23, 2016

Fair enough.

March 23, 2016

German for French speakers graduated to Phase 3 this week too: . :)

March 22, 2016

Thanks, lizsue. I added an errata.

March 28, 2016

You're welcome. :)

March 28, 2016

Go Vietnamese! ;-)

March 22, 2016

This still says under construction, is that accurate?

March 25, 2016

Unfortunately so, but now it is complete!
