.si is the Internet country code top-level domain (ccTLD) for Slovenia. It is administered by the ARNES, the Academic and Research Network of Slovenia. In 2010, the registry has hosted 80,000 domain names. In 2012, that number increased to 100,000.
Domain hacks for the .si TLD are quite popular, since si is second person singular of the verb to be in the Slovene language. As such, many domains have been created that are using such domain hacks, one of the most popular being zadovoljna.si ("You are pleased", female form).
Sí also translates from Spanish as yes, so the TLD has been used by some Spanish-language websites. A notable example of this is the Mexican political party MORENA, whose website is found at morena.si.
