Łasinek

Łasinek is a Polish surname. It is relatively uncommon and likely originated as a diminutive or derivative of a given name or occupational name related to the word "łasica," which translates to "weasel" in English. The surname could have arisen from a nickname given to someone thought to resemble a weasel in some way (e.g., being quick, nimble, or slender) or from an association with hunting or trapping weasels. Further research into Polish genealogical records and historical naming practices would be needed to determine the precise origin of the name for specific families bearing the surname.
