Name origin

The formation of this name begins with the ancient Arabic name for α Boo: al-simak al-ramih, "the Lance-bearing simak" (the meaning of simak is uncertain). It seems that later Arabic poets expanded upon this name by making mention of some separate "lance" (al-rumh) that accompanied the star α Boo. Subsequent Arabs attempted to identify this fictitious lance with actual stars, sometimes saying it was η Boo with nearby stars, sometimes saying it was "η Boo alone" (where "alone", in arabic, is written mufradan). From these discussions came, with a slight copying mistake in the Arabic, the erroneous Arabic name mufrad al-ramih, roughly translating as "the Isolated Single One of the Lance-Bearer". With a wrong vocalization and with abbreviation, this erroneous name, as "Muphrid", was applied in recent times.
