I'm from Russia and I understood 99%. It's incredibly. I must learn this language, but after studying Esperanto :)

The creator is obviously Czech (like me), based on his accent. It’s funny, coz 1. we, Czechs, all understand Slovak, that is much more similar to other Slavic languages than Czech, 2. people 45+ all learned Russian in school and 3. we love traveling to Croatia and speaking weird mix of Slavic languages there 😄

Hi, Im from Poland and when I saw this video I was shocked. It was totaly amazing to me that someone created common language for all slavic people. It is very easy to understand and it would be fantastic to use this language as much as english because we - the Slavs we all have same roots and we should be close to each other also by using this language. Pozdav dla vas

Pratim razvoj tog jezika vec godinama.. Drago mi je sto postaje svre popularniji.

I'm Polish and I could understand literally everything but I have to admit it's because I'm very interested in the Slavic languages and already tried learning most of them, especially Serbian and Russian. Also had much contact with Slovak, so yeah it was easy but anyway, I think that language experiment is working really well.

Im from Belarus and i can understand any slavic language if the speaker speaks slowly

Pozdrav ko vsim, slovjanski brati :)
Поздрав ко всим, словjански брати :)

Here's a funny thing: If you copy an Interslavic text into Google Translate and select the setting "Detect language," the automatic translator will usually take it to be written in either Slovene or Croatian, and the translation comes out surprisingly accurate. I've tried this several times myself and still can't wrap my head around how that works.

I am a Slovak and I perfectly understood this video in Interslavic. I thought it was because Czech and Slovak are very close to this language (as Vojto Merunko said later in the video). I am impressed that also other Slavs (you as a Serbian, Pole in the video, Bulgarian and Croatian in other videos...) understand almost everything. I wish this language were learned at schools in our countries.

An interslavic speaker ought to do a travel vlog using only interslavic on travels through the Slavic countries.

being Russian can understand nearly 100% of what he's saying.
but I also speak Ukrainian, so it helps a lot as well.

I'm Russian and neither  speak nor understand other Slavic languages.

I have already watched some videos with interslavic speakers (including the one you are watching here)

So, I can say that  interslavic project really works as I could easily understand at least 90-95% (maybe more) of what they say (even without reading the subs)

For me it's as if they speak Russian but with a bit  funny pronunciation))

Ја сам из Руссији и ја разумем овај језик.

iirc he is from Czechia, so he has a Czech accent when he is speaking Interslavic of which the Polish guy can understand from. Also Interslavic is a merger of 2 big inter-languages for slavic speakers. This guy did the mathematics and programming behind finding the most common words for each of the major branches of the slavic language family. Interslavic has both Latin and Cyrillic scripts (later on in the video he praise Serbians for understand both scripts when him and his team was doing on the field research).

All Slavs must unite !

Hey, I'm learning Serbian, and I've studied a bit of Slovak and Russian. Anyway, I'm not fluent in any of those languages, but I can understand general ideas in Interslavic. I'd like to learn it. I'm quite obsessed with the language, and I think it would be the only Conlang that I would learn.
A few weeks ago I've watched The Painted Bird, it's a movie in Interslavic.
Anyway I think that the language is very useful and the project is amazing. But I'd like that there were more sources in English to learn Interslavic.
Pozdrav svima iz Meksika!!

Sure, 100% understood. Oczywiście, wszystko zrozumiałem.

For people who now little bit of other slavic languages but his own, its understandable 100%.This is great

Ja jesm japonec, a ne jesm slovjan, ale govorim malo rusky (okolo A2) i ukrajinsky (-A1). Ja takože se učim druge slovjanske jezyky, kako i češsky, poljsky, srbsky i tutoj medžuslovjansky (na ktorom ja teraz pišim). Kako ja jesm skazal, nikaky slovjansky jezyk ne jest moj rodny jezyk, ale jesm viděl tuto isto video i razuměl više 80% (može biti daže 90%) bez subtitrov na anglijskom jezyku. Medžuslovjansky jest razumlivy ne toliko dlja rodnyh slovjanov, ale ješče dlja inozemcev, ktore se učit někaky slovjansky jezyk.

Красиво, душевно, понятно.
