Czech and Slovak - Are they Mutually Intelligible Languages?
Are the Czech and Slovak languages similar enough to be mutually intelligible? Well, I think it depends on who you ask. If you ask me, I’d say, definitely not.
From the time I moved to Slovakia and over the four to five years I lived there, many times Slovaks would insist that Czech is so similar to Slovak, that once you knew one language, you’d have little difficulty understanding the other. Well, I thought, that sure would be cool. I’d learn Slovak and then I’d be able to automatically understand Czech.
Hmm. A year went by and then two, all the while I’d be watching Slovak TV and see a Czech movie or Czech TV show and realize that though I could understand some Slovak, I couldn’t understand a single thing in Czech. Hmmm. More time goes by and still, really nothing. What was all that talk I heard about the languages being similar? Why couldn’t I understand any Czech?
Slovaks grew up being exposed to the Czech language. Children watched Czech language cartoons. TV shows and films in Czech are widely seen. At university students sometimes study from Czech text books. Of course this was really advanced while the two countries were united under Czechoslovakia. In present day the exchange is less so but still exists. With all of that exposure it’s no wonder that Slovaks understand the Czech language almost as native speakers.
After my husband and I moved to California, we lived with a roommate who was from Prague. My Slovak husband and our Czech roommate communicated by each speaking their own language. It was only after living for one year listening to Czech that I finally began to understand something. Now I can hear some similarities but I wouldn’t go so far as to say if you understand one language you will understand the other.
The Slovak language and the Czech language belong to the group of “western-Slavic” languages. Polish is the other member of this group. I’m certain that if Slovaks and Poles would have been exposed to each other’s language as much as Czech and Slovak are, then people would be saying that Polish and Slovak are so similar that if you speak one you certainly can understand the other.

Like anything, it takes practice before you can acquire "an ear" for another language. And for some it's easier than others. I was always so jealous of some people's abilities to pick up a language after a short time, where as I never could learn fast enough.

My friend Tana says that she understands much more Czech than her brother (5 years younger), because there was more Czech programming on TV when she was a kid compared to when him.

I wouldn't say if you speak Slovak you automatically can speak Czech, but it's very easy to learn. As Barbora said above, it's about the talent. I live with a girl who learned Slovak in impressive 4 months and can understand Czech almost as much as Slovak. Every now and then she asks about a particular word, but in general she understands everything. She just has a brain for it… based on what words she understands in Slovak she can imagine what the Czech word could mean without giving it a serious thought. There was a study that people which were exposed to more languages as children, their brain catches up more quickly. Regarding the Polish vs. Czech… I guess it’s not only about what people think, but there is a whole language science behind it. Czechs and Slovaks have simply much more common words than Polish and Slovak. Btw. part of the textarea of the comment form is hidden behind the „Tags“ in the right sidebar, so I cannot see some words I have written.

Personally, I think it also depends whether you are talking about the "official" Czech language or the rather slang Czech that is used in the western part of the Czech Republic. I studied 'spisovna cestina' (standard Czech) for many years and also lived in the Czech Republic. Native speakers were impressed that I knew the "correct" endings and used them when speaking while they used the colloquial versions. While I could understand the official language spoken on television, I sometimes had difficulty understanding common speech. I think if you compare 'standard Czech' with 'standard Slovak' they will be more similar than the slang versions of both. Most people, however, don't speak 'spisovna cestina' with the exception of some parts of Moravia.

Hmmm. Very interesting, Rob. I'm going to ask my Czech friend about this. It sounds like you are on to something here... .

Hi so here some inside from a Slovak. I live in east part of Slovakia. The official Slovak language is historically taken from Detva region so - middle of Slovakia, but each part of Slovakia has an special dialect better or less equipped to understand Czech or Polish or Russian.To tell you there are people in Bratislava that wouldn’t understand a thing my granny is saying. :-) And all the comments I read were right. the understanding depends on ability to learn languages or/and on the quality time spend listening to the other language. I am in my 30 so I remember the time as a child in Czechoslovakia - there were all the best stories and films in Czech only. And then as a student some books were only available on Czech too. But when I went for a holidays to Serbia or Croatia after a few days I could understand the language. So there its something into the Slavonic language group understanding mutually. And I would like to thank you that even abroad you still have love to beautiful Slovakia (land and language) in your hearts.

Hi todays Slovakian Language is historically taken from Martin region.... Territory called Great Moravia witch was Slovanian territory approx. in 9th century. Todays Slovakia was basically in the middle and Language with several modifications over the centuries and with influence from other languages such as Latin and German, rapidly changed , but base of languages in this territory is still same...Czech, Slovakian,Polish,Croatian,Slovenian.For example word ,,BREAD,, (Chleba) If you ask in shops from Baltic sea to Mediterranean south of Croatia everywhere you will get a bread. Its loooong time since 9th century but base of all this languages is coming from Great Moravia.Enough from history...
