Slovak · ~5M native, ~7M total including diaspora
Slovakia is a small but fully-integrated EU and eurozone country of ~5 million people at the heart of Central Europe, and Slovaks deeply value products that take the time to speak their language. Thanks to near-mutual intelligibility with Czech, a Slovak locale also reads comfortably to many of Czechia's ~10 million speakers, making it an efficient wedge into the wider Czechoslovak market of ~15 million EU consumers.
Slovak around the world
Slovak is spoken by ~5m native, ~7m total including diaspora. It is used as an official or working language across 6+ countries and territories.

What you gain from a Slovak locale
Slovakia is a fully regulated EU member state using the euro — no currency friction, clear GDPR/consumer-protection rules, and strong cross-border payment rails.
Slovak is a smaller language, so Slovak users notice and remember products that ship a proper sk locale. Goodwill and word-of-mouth are outsized rewards for a modest localization investment.
Slovak and Czech are largely mutually intelligible. An sk locale meaningfully serves part of the neighbouring Czech audience and is a natural stepping stone before shipping a dedicated cs locale.
Slovakia is home to ESET, Sygic, Pixel Federation and a growing startup scene — a technically literate audience that actively seeks well-localized tools.
Shipping Slovak on Localize.to
One sk locale covers Slovakia and the Slovak diaspora. Do not auto-reuse a Czech (cs) translation — while Slovaks understand Czech well, an explicit sk build is a strong respect signal.
The two languages share vocabulary and grammar but differ in spelling, phonetics and several high-frequency everyday words. A native Slovak translator produces copy that reads as local, not "close enough".
B2B and traditional brands use vy; consumer apps and younger audiences increasingly use ty. Choose once and keep it consistent across the UI.
Slovak uses three plural forms (1; 2–4; 5+), following CLDR rules shared with Czech and Polish. Use ICU MessageFormat — English's one/other will sound wrong.
Common questions
Technically most Slovaks understand Czech — but shipping only Czech reads as dismissive. A proper Slovak locale is inexpensive, noticed, and strongly preferred by Slovak users.
If your audience is more Czech, start with cs; if it is more Slovak or mixed, start with sk. Thanks to mutual intelligibility, whichever you ship first also partly serves the neighbour.
No. Standard Slovak covers the whole country and the diaspora. No sk-SK / sk-CZ distinction is needed for UI copy.
CLDR rules: one (1), few (2–4), many (5+). Use ICU MessageFormat or an i18n library with CLDR plural support and Localize.to will preserve the message structure through the API.
