Bohoslav Sulek (1816-1895), Slovak by birth, one of the most important Croatian linguists and lexicographers, made an enormous contribution to the enrichment of the Croatian literary language. He invented several hundred new terms that can be seen in his extensive dictionaries: German – Croatian (1860), Croatian – German – Italian Dictionary of Scientific Terminology (1874/75) and other. Many of them are now everyday Croatian words. Some of them also entered other South Slavic languages, including Serbian.
