How are you studying? (outside of Duolingo)
I learn new words by watching kids' cartoons in German as well as reading children's books. Sometimes I learn new words or word uses from music (if you do German you need to listen to Faun- they are the best band ever) but that's not as effective. Sometimes I visit http://www.ard.de/home/ard/ARD_Startseite/21920/index.html (news site) and pick out words I know.
I want to know how you study. Please state your language and how well it works for you. If you visit a specific website, please share with the community!
my Spanish level is a lot higher than what DL indicates. That is simply because when you truly love a language, you excel at it and you go above and beyond to learn it. I listen to Spanish songs all the time and now I even got the accent down. I do research about the language and its origins which simply fascinates me. I love how so many words are actually Arabic or of Arabic origins (Arabic is my native language). I also taught Sunday school at a Mexican church and I read daily quotes in Spanish and try to understand them without translation.
So to sum up, DL is great but it is definitely now enough. You need to be fully immersed in the learning process and more importantly, you have to absolutely love that language so you can enjoy learning.
Interestingly enough, Sicily also has a legacy of Arabic words, from its time under Moorish rule. I was fascinated to discover this when I was there this past fall. I fell in love with a local Sicilian wine called Zibibbo, which takes its root from the Arabic "zabib".
The food is also influenced by Arabic/North African cuisine in fascinating ways. Lots of raisins, saffron, couscous, etc...
Wow I didn't know that Sicily has its share of Arabic influence, but I guess it makes total sense! Another language that below my mind is Maltese language. It is a weird combination of Arabic, Italian and some English. But when I watch videos in Maltese I can understand most of their sentences.
Languages are the best!! I should totally leave my accounting profession and pursue a PhD in linguistics and history of languages. But I would be probably unemployed haha
Welsh - I mostly used the course here (as well as Memrise, to learn vocabulary) to get to grips with the basics, although I've started going through two books (Colloquial Welsh and Teach Yourself Welsh Grammar) in order to fill in any important gaps that may have been missed. I've also started reading through books written for learners - thankfully, there are a ton of short novellas written in Welsh specifically for adult learners (the books are generally under 100 pages, use relatively simple grammatical structures, and often include vocabulary lists for more advanced words) so it's a great way to practice reading and quick comprehension without being too much of a "jump" in difficulty after going through the Duo course. I'm reading them using Readlang - to quickly look up new words and to use CY>EN flashcards - and Memrise - to learn new vocabulary primarily through EN>CY flashcards. I've also started watching bits of whatever's on S4C (a Welsh-language channel) whenever I'm by the tv, although I haven't properly incorporated that into my learning "schedule" yet.
Latvian - at the moment I'm slowly working my way through the books Teach Yourself Latvian and Colloquial Latvian, although I also have a copy of Essential Latvian Grammar that I use for reference from time to time. Once I've finished these books, I plan on using the pasakas.net website (along with Readlang) to start reading basic children's stories, and I've also started a tiny collection of Latvian books I've bought that I hope to start reading within the next year or two.
Polish - Duolingo's been my primary source, although I've recently started working my way through the book Basic Polish Grammar and Workbook and I've used LingQ a few times (although I haven't found it that great, tbh).
French - I have a class every day so that takes care of most of my learning. I use Duo every day as long as having conversations with a classmate in French. I also read Wikipedia articles, and I understand about 70% regardless whether I know all of the words or not.
German - I self study German. Mostly Duo and watching language lessons on YouTube. I listen to a lot of German songs. I pretty much do the same as French.
Learning Spanish primarily. I watch as much television as I can with Spanish language on, with Spanish subtitles, and I can use the visual context to understand the subtitle text, while training my ear to listen to distinct accents. On Netflix in particular I find there is a large Spanish language selection, and the subtitles are often of excellent quality. Other than that, I got some high school level Spanish textbooks and read through them. My goal is to read a little bit of Don Quixote in the original Spanish! Working through it now in English to prepare.
Youtube, series (watching an Italian dub of Avatar: the Last Airbender at the moment) and lots of reading. I also practice in speaking a lot, but that's because I'm actually in Italy for a stay abroad; not everyone will have the same opportunity (and neither will I anymore when I have to return home soon).
