Czech language Orthography and spelling

Czech orthography is a system of rules for proper orthography in Czech. The earliest form of a separate Latin script specifically designed to suit Czech was devised by Czech theologian and church reformist Jan Hus, the namesake of the Hussite movement, in one of his seminal works, De orthographia bohemica (On Bohemian orthography). The modern Czech orthographic system is diacritic, having evolved from an earlier system which used many digraphs (although one digraph has been kept – ch). The caron (known as háček in Czech) is added to standard Latin letters to express sounds which are foreign to Latin. The acute accent is used for long vowels. The Czech orthography is considered the model for many other Balto-Slavic languages using the Latin alphabet; Slovak orthography being its direct revised descendant, while the Croatian Gaj's Latin alphabet and its Slovene alphabet offspring are largely based on it. The Baltic languages, such as Latvian and Lithuanian, are also largely based on it. All of them make use of similar diacritics and also have a similar, usually interchangeable, relationship between the letters and the sounds they are meant to represent.
