In the Romanian language the phenomenon of abbreviation has grown in the last decades of the last century. The procedure corresponds to the intense rhythm of life characterized by saving of time, space and energy. It meets the needs of contemporary man to express himself as concisely as possible. Although on abbreviation of words or wordgroups in Romanian many studies have been written, this issue still deserves to be called into question as many poorly unknown practical aspects concerning spelling, pronunciation and their appropriate decoding have remained unsolved yet. That is why in this article, on the basis of abbreviations extracted mostly from republican periodicals, we have tried to make some comments, suggestions, recommendations, additions to what has been published so far, especially for abbreviations formed from initials (successive and non-successive letters and sounds) of compound proper names which are quite common in contemporary language. Most of difficulties faced with this type of abbreviations refer to content (decoding), they are related to nominal flexion (gender, number, case, articles), to capitalization (with or without a dot), to their connections with general vocabulary.
