Slovak is a West Slavic language spoken predominantly in Slovakia, where it is the official language. It is also spoken by Slovak communities in various parts of the world, particularly in neighboring countries and among expatriate communities. Slovak is a member of the Indo-European language family and shares similarities with other West Slavic languages like Czech and Polish.

The Slovak language uses the Latin alphabet with diacritics, including various accent marks, to represent specific phonetic features. Slovak has a grammatical structure typical of Slavic languages, including a system of grammatical cases and a complex verbal aspect system.

In Slovakia, efforts have been made to promote the use of the Slovak language in education, media, and official communication. Slovak literature has a rich tradition, encompassing both classical and contemporary works. However, like many other languages, Slovak faces challenges in the era of globalisation and the increasing influence of English. Nonetheless, there are ongoing initiatives to preserve and promote the cultural and linguistic heritage of the Slovak language.
