Krasnoludek (Slavic)
Krasnoludek or krasnal is the Polish name for a mythological type of gnome or dwarf, common in many Polish and translated folk tales (for example, Brothers Grimm Snow White and the Seven Dwarfs is translated into the Polish language). The word krasnoludek comes from the old Polish krasny, ("red, colorful," "nice-looking," or "good") and Polish ludek (small person or human-like creature).
They resemble small humans and wear pointy red hats. Due to the popularization of fantasy literature, they are now differentiated from both gnomes (Polish: gnom) and dwarfs (Polish: krasnolud), both of which are used in fantasy literature context, while the word krasnoludek still remains mostly the domain of older folk tales. The word krasnal ogrodowy is also used to describe garden gnomes.
