Cool, you are always very quick.

January 25, 2015

Wspaniale! Dziękuję.

January 25, 2015

Here's the course for Maths in Hindi!

January 27, 2015

बहुत धन्यवाद! (Don't ask more Hindi from me :p)

January 27, 2015

Wow that was good! आप अवश्य हिंदी सीख सकते हैं!

January 28, 2015

Hey, David. Aadit made the Hindi course. I had no participation in its creation. So make sure you attribute (oh I love this word) it to the correct person. :P

January 28, 2015

And you didn't answer my question, should I add you as contributor for the hindi course so that you can also edit the words?

January 28, 2015

And maybe you didn't look at your profile. :P (Sorry, but আমার প্রচণ্ড গরম হয়ে রয়েছে) That's okay. I think I'll just leave the Hindi courses to you. I'm not that good at Hindi, anyways...

January 28, 2015

Okay তুমার.... wish? :P I wish I knew vocabulary!

January 28, 2015

তোমার, not তুমার। ;P

January 28, 2015

Oh! Sorry!

January 29, 2015

Fantastic. I can't believe I haven't seen this before.

With the topic of math and numbers, this comes to mind:

"Here's one (somewhat trivial, but illustrative) example of the relative complexity of languages: the number 2.

English, Spanish, Dutch: 1 form (two, dos, twee)

Portuguese: 2 forms (dois/duas) - depending on gender (2 - masculine feminine)

Croatian: 7 forms (dva, dvije, dvoje, dvojica, dvojice, dvojici, dvojicu) - depending on gender (3 - masculine, feminine, and neuter) and case in one specific form. There were other variants historically but they're not used anymore.

Polish: 17 forms. Depends on gender (3), case for all forms. Pretty much all these forms occur in regular speech (6-11 less often than the others)

17 grammatical forms for the number 2

  1. dwa
  2. dwie
  3. dwoje
  4. dwóch (or dwu)
  5. dwaj
  6. dwiema
  7. dwom (or dwóm)
  8. dwoma
  9. dwojga
  10. dwojgu
  11. dwojgiem
  12. dwójka
  13. dwójki
  14. dwójkę
  15. dwójką
  16. dwójce
  17. dwójko"
January 25, 2015

Ok, you made your point. I'll just strike off Polish from my "next to learn list" and replace it with Dutch. :D

January 25, 2015

If you want to reach a high level of fluency, I think trying to learn Polish is a great challenge; I always feel more rewarded when I overcome an obstacle that originally seemed insurmountable than when completing a smaller goal.

There are plenty of ways that we can classify the "relative difficulty" of languages, but at the end of the day, I think the hardest language to learn is one that you don't want to learn. If you really want to learn any language badly enough, you can do it, no matter how difficult anyone thinks it is to learn.

January 26, 2015

Premature congrats on your 666 day streak :)

January 26, 2015

Wow! So do Polish people think learning other languages is a piece of cake then?

January 26, 2015

Well, unfortunately, no. Most people in Poland find it difficult to learn a foreign language (I think it's basically the same as in other countries). Maybe we're just so overwhelmed by our language ;) - a lot of people even have difficulties with using Polish correctly. I think that even languages that are considered "easier" are troublesome if they aren't similar to what we know. Okay, I understand and can "feel" the cases, but now German has only four of them, they are used in a completely unknown way and I have to learn them from scratch! And English, don't get me started. What are the articles? Simple, continuous, perfect... what?! We don't have such things. Well, we can do something similar by using prefixes, but still, not the same. And even if something is too easy... Seriously, it CAN be a problem to realize and understand that only one foreign word translates to 15 in your mother tongue (because there are no cases or endless suffixes or prefixes...)

January 26, 2015

I think one of the hardest thing for those of us coming from English and learning languages like Russian (6 cases), or Polish (7 cases), (or maybe even German, with 4 cases, I'm not sure) is applying grammatical cases, because we don't really have them in English.

If somebody speaks to me in Ukranian, I can understand a lot of what they're saying, and some Russian isn't too different either. I've heard that if you've studied or learned other Slavic languages, Polish will be easier.

January 26, 2015

I always wonder if there is a perfect roadmap that makes things easier to learn European languages... first English, then a romance language (introduces genders and more complex conjugations of verbs), then German (introduces cases and neuter gender), then Slavic languages (more cases, declination of nouns themselves instead of articles), and then ?

I'm studying Russian right now, and as an English speaker, I think it would have been much harder to grasp without having studied some German first.

January 26, 2015

That's a very interesting idea. I'm sure there are a lot of examples where learning one language helps with learning another. I'm starting to feel that the more languages you try to learn, the easier it becomes. You become analytical, and you compare what you've learned in other languages to the languages you're learning.

I've heard all kinds of studies that babies are linguistic geniuses and that it becomes more difficult to learn languages after we pass some age. That was sometimes slightly discouraging to me. Recently, I became aware of a study that said that adults can learn languages just as well, if not even better than children, under certain circumstances.

I always took the studies that said, "You're past your prime for language learning" as the truth without giving them much thought. It doesn't matter whether it's true or not. If they are, I'm just going to have to work a little harder to get a little further every day.

January 26, 2015

Maybe Esperanto would be a good second. English has 2 cases (genitive it the 2nd one) for nouns, 3 for pronouns (I, my, me), Esperanto does not have a genitive but adds an accusative, and adds agreement in adjectives for singular/plural and case. It introduces a future tense, but does not conjugate for person. It introduces glide-free vowels and a voiceless frictative, but has no length or tone distinctions. Not a lot of idiom. I'd say it's a good step towards Spanish or German.

February 21, 2015

I think Esperanto has value in and of itself, but there's a lot of evidence that it makes an excellent stepping stone for further language study, and is a relatively painless way to get introduced to things like cases and to adjective agreement, etc. There are studies that strongly suggest that its benefits aren't just anecdotal.

February 21, 2015

I definitely think German is a relatively kind way to get intro'd to cases. Russian was my first ever declining language, and it was pretty much an case of being thrown in the deep end...

February 21, 2015

Some additions to Croatian: dvaju, dviju, dvama, dvjema, dvojicom, dvoma, are forms that are also in use.

January 31, 2015

Oh dear!! I'm so late this week!!! D: I've been really busy (mugging up Geography). Sorry. Here's the Bengali course : Duolingo - Bengali Bonus Skill : Mathematics. :)

January 28, 2015

No problem! (Maybe my fault :p)

January 28, 2015

I will edit the Bengali course a bit. Because I forgot to add something...

January 28, 2015

No problem. :) You can always edit any previous course if you want to add something or made a mistake. :)

January 28, 2015

Matematika! By the way, thanks for the Dutch course! I have been looking for math operation in Dutch for a while.

January 26, 2015 Here is the right link. Sorry for posting the wrong one yesterday.

January 27, 2015

No problem. :) Thank you!

January 27, 2015

Didn't you want to give us the link to your course and put Dutch instead by mistake? :)

January 26, 2015

Yes! Sorry, my mistake. I will correct it ASAP. Thanks for reminding!

January 27, 2015

Maybe the Javanese list can help you a bit, since there are some similar vocabularies

January 27, 2015

I have finished the course since yesterday. Copied the Dutch tab link by mistake, though. I will give the correct link when I am on PC.

January 27, 2015

Nice..If you need any help with the Bahasa Indonesia bonus skills just let me know ;D

January 27, 2015

Sorry it took a while, I kind of forgot because I was really excited about starting a German club. Here it is:

January 29, 2015

No problem! Real life is more important. ;)

January 28, 2015

A thousand times sorry! Added it. :) (And now for real...)

January 28, 2015

My computer decided to restart in the middle of this one headdesk but maths and physics for Esperanto are (will be...) here
