It has the traditional name Merga, occasionally spelled Marrha[10][11] or in full El Mara el Musalsela,[11] from the Arabic المرأة المسلسلة al-mar'ah al-musalsalah "the chained woman". Another occasional name was Falx Italica,[11] from the Latin falx ītalica "billhook". In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN)[12] to catalogue and standardize proper names for stars. The WGSN approved the name Merga for this star on 12 September 2016 and it is now so included in the List of IAU-approved Star Names.[9]
