Lextum8 from Team EO for ES wrote 2 days ago:

¡Curso en beta!

Con todo lo que ocurrió, olvidamos avisar que Duolingo al fin habilitó el curso de esperanto para hablantes de español! Quería dejarlo aquí para que todos los que entren a la incubadora (o a las actualizaciones semanales de la incubadora por parte de jitengore en el foro de Duolingo en inglés) se enteren de esto, divulguen, y puedan probar el curso.

El curso está disponible sólo desde la web. Pueden acceder por medio de cualquier navegador en sus celulares y es bastante amigable. El curso llegará a las aplicaciones cuando Duolingo esté seguro de que nuestro curso es bastante estable, en el sentido de no recibir tantos reportes de errores.

Luego el objetivo será que nuestro curso pase a la fase final, que implica gran estabilidad y confiabilidad del curso.

Hoy se cierra una etapa muy larga, pero es sólo el comienzo. Todos vamos a seguir trabajando para llevar el Esperanto a los hablantes del segundo idioma con más hablantes nativos del mundo, que tienen un merecido lugar de relevancia en el mundo de Duolingo, por lo que recibirán un curso cada vez mejor.

Les informaremos cuando sepamos de la apertura del curso en las apps.

Gracias por toda su paciencia!

adding PH-exclusive words

Hi guys,

I still can't seem to successfully add a word. These are some words I think should be added in the list: - kalabaw/carabao - Manila - Quezon City - mangga/mango

Thanks! :)

DJGeoRob from Team Tagalog added 6 hours ago:

Just being a bit picky, historically speaking

The lighter blue shade of the Philippine flag that I see in the icon was only used during the Martial Law period. Maybe we can request to have it changed to the actual royal blue shade that is used today?

Happy (almost) Halloween! ^^

  • 800/2497 words
  • 91/100 images

In the past day our total number of words has dropped. The skeleton tree that we started with has placeholder skills full of vocabulary. As we prepare to convert those for our course, we delete many of those placeholders and fill the skills back up with new words. As we make ready to next few skills to be developed, our total number of words will rebound quickly.

In the past week we completed Written/해라체 and Sino-Korean Numbers. As we finish up with Past Tense we are also looking ahead to Food 2, Time, and Gerund.


The Esperanto for Spanish course is now in beta! And team Tagalog is further accelerating their progress!!

Would love to hear more from the Swahili team :( I am really looking forward to the course.

October 30, 2016

I've messaged one of them, they said they're about to start the recordings.

November 1, 2016

Great to know they're still working on it! So excited for the course.

November 2, 2016

4 courses on 99/ agonisingly close...

As always, thank you jitengore for your helpful and informative posts :D

October 30, 2016

I've been here long enough to know that today being the day Romanian is supposed to come out means nothing... Still psyched though.

October 30, 2016

Every night, every day, every hour, checking for Romanian! They are still working on Text-to-Speech... see more updates here.

October 30, 2016

I have to admit that all of this suspense is making me want to try Romanian. I hadn't planed on it when I first saw that they were developing it, but any course which has been in development longer than I have been on Duolingo tugs my curiosity.

October 30, 2016

There is pretty much no way I can't do the Romanian course at this point anyway, but I really think it could turn out to be the most interesting of the Latin languages, even though it is usually overlooked.

October 31, 2016

Yay teams Tagalog and Korean!

October 30, 2016

Tagalog is making super quick progress! Can't wait to see a course coming out soon!

October 31, 2016

21% already for Tagalog. I'm so excited. Natutuwa akong

October 31, 2016

Maraming salamat para ng lingot

October 31, 2016

No problem! I have waay to many. Maaari kang magkaroon ng isa pa. :)

October 31, 2016

Qué bueno que ya tenemos el curso de Esperanto para hispano-hablantes. Felicitaciones a todos los que hicieron esto posible.

So great we now have the Esperanto course for Spanish-speakers. Congratulations to everyone who made this possible.

Unofficial update on Yiddish, from Mendl, one of the contributors:

I am moved by your desire for Yiddish course on Duolingo, as soon as ever possible. But I beg you to wait just a little bit longer. I admit (and beg your forgiveness for the fact) that we are no masters of public relations – and I do not question your disappointment nor the angst we’ve caused you all by not keeping you up-to-date as regards the course. And yet, I have the nerve to ask you to wait just a short while longer, because as far as Yiddish teaching goes, we really do bring experience and an earnest approach to the work (no matter what shlimazels we may be as regards PR). And although it appears that the course has simply come to a halt, the metrics on the website do not in fact reflect the actual state of the course today. I will post about all of that at length soon, but in the meantime I will say: our progress has not been visible on the website, because we have been working offline. This is for a few reasons, primarily to avoid specific obstacles we encountered in our first go at building the course. At any rate, the work will very soon transition online, and you will all see the course take shape as it currently stands, and will see the work that still remains before us. I assure you, there is not so very much as you expect.

German for Italian already finished their course. " 12 hours ago Liebe Alle,

Oggi il nostro team ha raggiunto un traguardo importante: 100%!! Questo significa che il corso è completo ed è stato mandato al team di Duolingo per le necessarie verifiche. Quindi, a questo punto il rilascio in Beta non è più nelle nostre mani, e siamo ansiosi tanto quanto voi.

Il nostro lavoro però non è finito. C'è ancora tanto debugging da fare, e i vostri report in Beta ci aiuteranno tantissimo a perfezionare il corso.

Bis bald,


in English (google translate)

"Today our team has reached an important milestone: 100% !! This means that the course is complete and has been sent to the Duolingo team for the necessary checks. So, at this point release in Beta it is no longer in our hands, and we look forward as much as you.

But our work is not finished. There is still much debugging to do, and your report will help very much in Beta us improve the course.

Bis bald, Marco."

October 30, 2016

Awesome! Hopefully Italian for German speakers will be next. :)

October 30, 2016

Great news! That's another marathon process nearing its end... It's been in the Incubator since September 2014!

October 30, 2016

Glad to see that Esperanto for Spanish speakers finally hit beta, I noticed just over 24 hours ago and pounced at the opportunity to reinforce both languages :))

October 31, 2016

Wow! It must have taken hours to write this - it definitely deserves 100+ upvotes!

October 31, 2016

honestly, exceptional progress by the korean and tagalog teams. really look forward to those

November 1, 2016

What? No update and progress from the Czech team?

October 30, 2016

There are some mysteries out there, but the status of the Czech course should not be one of them. At least this aliasing phenomenon may eventually create an illusion of a 2% increment. One can dream big.

October 31, 2016

I am eagerly looking forward to today's weekly update :-)

November 6, 2016

Working on that now :)

November 6, 2016

Lol :)
Thank you very much.
Muchas gracias.
Grazie mille.
Muito obrigado.
Maraming salamat.
Salamat kaayo sa.
