The author's main aim was to present new problems or inconsistencies emerging in the spelling of acronyms. This is important since acronyms constitute a part of the Hungarian word stock that is undergoing changes at the fastest rate today. Deficiencies in the 11th edition of the Rules of Hungarian Orthography have been clearly pointed out by this empirical study, suggesting furthermore that phenomena diverging from the orthographical norms have to be traced back to some serious reason(s). A deeper understanding of those reasons could be based on an even more extensive study. One thing is certain: in creating the 12th edition of the rule book, tendencies occurring in the everyday practice of writing ought to be taken into consideration, and gaps in the regulations have to be filled in, in accordance with the general logic of Hungarian orthography.
