Mizar

The IAU catalogue's account

Ultimately from the Arabic word al-maraqq, "the Groin," used in the Arabic Almagest in describing β UMa. Correct transliterations of almaraqq in the Medieval Latin Almagest were mirac and mirach. However, Early Modern scholars confused these words with the Arabic word mi'zar, which had equally been transliterated and corrupted in Latin as mirac, mirach, etc. Subsequently the mistaken mi'zar, written as "Mizar," was applied as a star name to β UMa, and it became transferred to ζ UMa in late Early Modern times.
