Czech Republic vs. Czechia
I never thought that one day I would write anything like that: Some people strongly oppose the use of the name Czech Republic. Instead, they want you to use the short form Czechia. The name Czechia was officially introduced in 2016. And why not? Even the Slovak Republic has a short form: Slovakia. So what is bad about using also Czechia? Probably nothing. Apart from the similarity to Chechnya. It is just a question of personal preference.
Officially, you can now choose between a long and a short form. But, in reality, you will be surprised how emotionally many Czechs react if your choice doesn’t match theirs. Just read the comments under the following video, or post a tweet with the hashtag #czechrepublic and wait for the lecture.
Edit: After some discussions behind the scenes it might be necessary to clarify my own standpoint: I suggest that you use any of the two official names, when talking about the country in a context that requires an official name. And I oppose to being pushed into any preference. I myself will continue to preferably use “Czech Republic”. And since this blog is not a collection of deadly serious texts and much is just ironic, I might as well use “Czechia”.
