Slovak orthography
The first Slovak orthography was proposed and created by the Slovak Catholic priest Anton Bernolák (1762–1813) in his Dissertatio philologico-critica de litteris Slavorum, used in the six-volume Slovak-Czech-Latin-German-Hungarian Dictionary (1825–1927) and used primarily by Slovak Catholics.
The standard orthography of the Slovak language is immediately based on the standard developed by Ľudovít Štúr in 1844 and reformed by Martin Hattala in 1851 with the agreement of Štúr. The then-current (1840s) form of the central Slovak dialect was chosen as the standard. After Hattala's reform, the standardized orthography remained mostly unchanged.
