Using [[Mendeleev's predicted elements|Mendeleev's nomenclature for unnamed and undiscovered elements]], meitnerium should be known as ''eka-[[iridium]]''. In 1979, during the [[Transfermium Wars]] (but before the synthesis of meitnerium), IUPAC published recommendations according to which the element was to be called ''unnilennium'' (with the corresponding symbol of ''Une''),<ref name="iupac">{{cite journal|author=Chatt, J.|journal=Pure and Applied Chemistry|date=1979|volume=51|pages=381–384|title=Recommendations for the naming of elements of atomic numbers greater than 100|doi=10.1351/pac197951020381|issue=2|doi-access=free}}</ref> a [[systematic element name]] as a [[placeholder name|placeholder]], until the element was discovered (and the discovery then confirmed) and a permanent name was decided on. Although widely used in the chemical community on all levels, from chemistry classrooms to advanced textbooks, the recommendations were mostly ignored among scientists in the field, who either called it "element 109", with the symbol of ''E109'', ''(109)'' or even simply ''109'', or used the proposed name "meitnerium".<ref name="Haire" />

The naming of meitnerium was discussed in the [[Transfermium Wars|element naming controversy]] regarding the names of elements 104 to 109, but ''meitnerium'' was the only proposal and thus was never disputed.<ref name="IUPAC94" /><ref name=IUPAC97>{{Cite journal|doi=10.1351/pac199769122471|title=Names and symbols of transfermium elements (IUPAC Recommendations 1997)|date=1997|journal=Pure and Applied Chemistry|volume=69|pages=2471–2474|issue=12|author=Commission on Nomenclature of Inorganic Chemistry|url=http://publications.iupac.org/pac/pdf/1997/pdf/6912x2471.pdf|access-date=December 19, 2023|archive-date=October 11, 2021|archive-url=https://web.archive.org/web/20211011132719/http://publications.iupac.org/pac/pdf/1997/pdf/6912x2471.pdf|url-status=live}}</ref> The name ''meitnerium'' (Mt) was suggested by the GSI team in September 1992 in honor of the Austrian physicist [[Lise Meitner]], a co-discoverer of [[protactinium]] (with [[Otto Hahn]]),<ref>{{Cite journal
