2009, the Minority Language Act 184/1999 Z.z., in its section (§) 6, contained the variously interpreted unclear provision saying that "When applying this act, it holds that the use of the Czech language fulfills the requirement of fundamental intelligibility with the state language"; the state language is Slovak and the Minority Language Act basically refers to municipalities with more than 20% ethnic minority population (no such Czech municipalities are found in Slovakia). Since 1 September 2009 (due to an amendment to the State Language Act 270/1995 Z.z.) a language "fundamentally intelligible with the state language" (i.e. the Czech language) may be used in contact with state offices and bodies by its native speakers, and documents written in it and issued by bodies in the Czech Republic are officially accepted. Regardless of its official status, Czech is used commonly both in Slovak mass media and in daily communication by Czech natives as an equal language. Czech and Slovak have a long history of interaction and mutual influence well before the creation of Czechoslovakia in 1918, a state which existed until 1993. Literary Slovak shares significant orthographic features with Czech, as well as technical and professional terminology dating from the Czechoslovak period, but phonetic, grammatical, and vocabulary differences do exist. Other Slavic languages Slavic language varieties are relatively closely related, and have had a large degree of mutual influence, due to the complicated ethnopolitical history of their historic ranges. This is reflected in the many features Slovak shares with neighboring language varieties. Standard Slovak shares high degrees of mutual intelligibility with many Slavic varieties. Despite this closeness to other Slavic varieties, significant variation exists among Slovak dialects. In particular, eastern varieties differ significantly from the standard language, which is based on central and western varieties. Eastern Slovak dialects have the greatest degree of mutual intelligibility with Polish of all the Slovak dialects, followed by Rusyn, but both Eastern Slovak and Rusyn lack familiar technical terminology and upper register expressions. Polish and Sorbian also differ quite considerably from Czech and Slovak in upper registers, but non-technical and lower register speech is readily intelligible. Some mutual intelligibility occurs with spoken Rusyn, Ukrainian, and even Russian (in this order), although their orthographies are based on the Cyrillic script.
