The name Mut has Slavic origins and is a nickname-type personal name. It evolved from the verbal root "mutiti," which means "to muddy" or "to chatter." This name is known in several Slavic dual-rooted and simple forms that existed in the 16th - 17th centuries. For instance, the name Mut was recorded in sources (Balzer 164) in 1565, along with the patronymic Mutenko (LCS 212). There are also ancient Serbian compound names such as Muṭivoda (Grk 132) and the modern Croatian name Mutimir (Śim 245), which share similar roots. Additionally, the Boyko name Mutko, which was recorded in 1607 (Balzer 113), derives from the name Mut.
