The Slavonic written legacy of the Romanian Speaking Lands has attracted so far the interest of Romanists, historical dialectologists and text critics. However, its lexicographical treatment has not been satisfactory so far. The paper tries to sum up the history of the terminological delimitation of the Romanian Slavonic legacy and presents an overview of the lexicographical attempts with their short evaluation. The focus is given to the ambitious project of a Romanian Slavonic Dictionary run in the 1960s–1980s and provides the reader with a few proposals on the manner of a lexicographical treatment of the Slavonic texts from Romania.
