In 1931, the Matica slovenská published a new Slovak language standard prepared by Czech linguist Václav Vážný, the head of the Department of Linguistics of Matica. In contrast with older works including those published in Czechoslovakia, the standard had an official character and was approved and recommended by the Ministry of Education led by Slovak minister Ivan Dérer. The standard was inspired by the official ideology of Czechoslovakism and tried to align both languages by the codification of numerous Czech words and forms not existing in Slovak. It raised negative reactions, and the board of Matica promised its revision. Although a new official standard was not published before the breakup of Czechoslovakia in 1939, a new standard of Matica was used along with Vážný's standard.
