The Polish surname Lizoń (pronounced "Lee-zon," with a soft 'n') is unrelated to the French version. It's a cognominal surname, derived from a nickname. The most cited origin is the verb lizać, meaning "to lick," possibly referring to a flatterer or someone with a sweet tooth.
An alternative theory links the variant Lezon to the verb leźć, meaning "to shuffle," describing someone with a distinct walk. The diacritical mark (ń) is often lost when anglicized, leading to confusion with other origins.
