New Tree Development - Update on Progress

Hey everyone!

As the second tree’s development continues, we thought it would be appropriate to post another update of its progress.

  • Having taken into consideration the official guidelines for teaching Greek grammar, we have planned the new tree so that it can cover all the necessary grammar for the B2 CEFR level. Accordingly, the new course will contain more than 3,000 words. We are confident that once released, our course will be one of the longest courses that are available on duolingo, teaching effectively all the necessary vocabulary and grammar that one needs to reach the B1 level, having a solid knowledge of the Greek language.

  • More than 85% (almost 87%) of the courses’ sentences have been added, but the new tree probably won’t be available until 2020. We know this might be frustrating for some learners who have been around for quite a while, but Duolingo is an app that’s constantly changing. We have to keep adjusting things every once in a while, and that includes adding more sentences than the minimum required, so that the crown system functions effectively. Apart from that, there’s also the tree’s automated verification process, which might take a considerable amount of time.

  • Bonus Skills and Stories are not yet available for this course, as they are not for many more courses on Duolingo. We don’t know when these features will become available, but we’ll keep you posted if there is an announcement about it from Duolingo staff, in the future!

  • We are aware that there might be a few learners who are displeased by some of the changes made in the old tree. If that’s the case, please feel free to express your concerns and share your ideas in the comments, politely. Constructive criticism is more than welcome!

The old tree (currently released) consists of 74 skills and 1949 words.

The new tree consists of 92 skills and 3110 words.

Here are the changes that have been made:

  • Some skills have been renamed.

  • Some words have been deleted from existing skills.

  • Double accents have been corrected.

  • Unnatural sentences have been deleted.

There is still a possibility of new additions. If there is any new learning material added to the course, we’ll make sure to post an update in the next few months!

We can’t thank you enough for all your support, comments and feedback. It has helped us to keep striving for improvement, for a better language learning experience, for you. And, of course, thank you for being patient. We’re looking forward to this tree’s release as much as you do.

Happy learning,

Καταπληκτικά!! So looking forward to the enhanced tree and grammar level B2. That said, the current tree has made a major difference for my somewhat futile attempt to master modern Greek. It has been an enormous support for the various courses (paid $$$) I have followed. The green owl rocks. Thank you, Ελληνική Ομάδα, for your effort and for keeping us posted on your progress <3

July 27, 2019

Aw, thank you for your nice words :D And we're also glad to hear that the current course ahs helped you in your learning journey. We hope you'll stick around for the second tree's release! ^.^

Very good news! I stumbled across Greek for a holiday and am now hooked ... μου αρέσει η ελληνική

I have lots of praise for the team who have helped turn a complicated challenge into something manageable.

I even like being able to say "This is not my bear" ... a must for all holiday-makers.

ευχαριστώ πόλη

July 28, 2019

Thank you for your kind words, too. :)

August 1, 2019

So the gerund lesson got replaced participles lessons,interesting.

July 26, 2019

Yes, indeed. Gerund isn't a term that's used in Greek grammar. And since passive participles weren't included at all, we decided to teach both properly. ^.^

July 27, 2019

Will there be a post on the duolingo in English forum informing potentially interested students on the changes?

July 28, 2019

Ι don't think so. It might be marked as irrelevant, since it's about the Greek course specifically. But, we could consider it for a future update ^.^

July 28, 2019

Excellent! İ need a good prompt to go back and run through the Greek tree again and with the additional vocabulary I might be able take that next step towards understanding. I really enjoyed the challenge of Greek and would like to take it further.

July 27, 2019

Thank you! We're excited to have you back for Greek Course 2.0 , when it gets released! :)

July 27, 2019

Great news! Thanks for all the hard work. And if the new tree isn’t ready until next year, I’ve got at least 5 months in which to complete the current one! Nothing like a deadline for motivation!

July 28, 2019

That's the way to go! :)

July 29, 2019

AWESOME! These are the kinds of changes we need on duo! Not a new website layout! Thank you! I don't take Greek, but I can appreciate your hard work!

July 28, 2019

Thanks for the update and for all your hard work! What will happen to my progress on the current tree when the new one is released?

Also, a humble request: In the "Questions" skill, would it be possible to add in more practice specifically to help distinguish between τι and ποιος/ποια/ποιο? I don't think I'm alone in finding it difficult to determine when to use which. I was in Greece earlier this month and even some of the locals admitted that it can be confusing if you're not speaking Greek every day.

Ευχαριστώ πολύ!

July 28, 2019

Ευχαριστώ πολύ την όλη Ελληνική Ομάδα! The course is already great, so any further improvement can only be received with gratitude and excitement.

If I may, I would like to make a suggestion. If I understand correctly, the tree will gain a substantial amount of new material but is going to lose some of the old. Please keep that material as lessons at the end of the tree. The ones of us who have already gone through those words would like to keep practicing them (as to me, even επίρρημα, μετοχή, and so on), and extra vocabulary never hurts!

Thanks again for all your work!

August 5, 2019

very well done i have always wanted to learn greek but found the current course quite hard

July 26, 2019

Thank you Marcus ^.^

I wouldn't say it's hard, but it's indeed a bit more compicated than it needs to be. We tried to make it as simple as possible, while also adding useful material that was missing. We hope you'l be around to check out the new course, when it eventually rolls out!

Happy learning ^.^

July 26, 2019

Well done!

July 26, 2019

Thank you for your efforts!

July 26, 2019

Thank you for your support, and for taking the Greek course. ^.^

July 27, 2019

I hope other courses will reach level B2!

July 27, 2019

That's great greek team! Keep plowing! Thanks for the update, I had been wondering about the progress of the new tree.

July 27, 2019

Thank you for your support ^.^

Indeed, this update took a while to be posted. There have been quite a few changes these past few months, and there was a certain amount of progress to be made, in order for us to have something more complete. We'll make sure to post them a bit more frequently in the future!

July 27, 2019

Thank you so much for your hard work on this - it has seriously helped me! I am very excited for the new tree...

July 30, 2019

We're so glad to hear that the course has been helpful! We hope you'll stick around to give us your feedback on Greek 2.0! ^.^

August 1, 2019

I'm not even learning Greek and I'm excited!

August 1, 2019

Congratulations Ελληνική ομάδα! I appreciate your devoted tries to improve the Greek tree. It is not an easy try and I guess it will be perfect!

August 7, 2019

Are there going to be tips and notes?

July 29, 2019

Of course ^.^ Almost all of them have been rewritten. We are currently working on a post to include all grammar related posts, so that we have only one sticky post, where everything's organized. New posts will be getting added gradually, in order for us to help learners a bit more until the new tree's release (and also because, when the new tree gets released, some sentence discussions will be deleted. We need to have a few reference points:) ). This will take a while though.

July 29, 2019

Is there any way to get into the new tree development process ?

July 29, 2019

What do you mean, exactly? To get into as in, to take part in the development process, or just see it?

July 30, 2019

Ευχαριστώ πολύ!

August 1, 2019

Εμείς ευχαριστούμε! ^.^

August 1, 2019

Will the new skill named 'Greece' mention anything about cyprus?

August 4, 2019

I don't want to be a bother, but when in 2020 do you estimate the new tree to be released? Also, if the new tree will be at a B1/B2 level, what would you consider the current tree's level to be?

August 7, 2019

Hi amazing moderators

After the change, any idea what our tree will look like? Does it all get reset, or just some new subjects appear and others stay completed if you have done them? What happens to your XP?


August 11, 2019

I believe that the system will treat as "known" all the common words between the two. So, for example, if you have the "food" skill golden, and the new tree adds a lesson with new words in that skill, it will not be golden anymore, but previous words/lessons will still be considered known.

August 11, 2019

Thanks ... while that might be a bit demotivating at first, it'll be very good practice too!
