The name 'Falets' is a diminutive variant of the Slavic personal name 'Khvalets', which originates from the verb 'to praise'. This name has been phonetically modified and is presented in a hypercorrect form as 'Falets' or 'Falc'. For example, in sources from 1552, it is mentioned as 'Palec Stepanowicz', and in 1565 as 'Luczka Falez'.
