Other local names were associated with the characteristics of its forms, its practitioners and their works, and schools of thought or study where it was popular. Many of these terms refer to the idea of "newness". Before the term "Art Nouveau" became de rigueur in France, le style moderne ("the modern style") was the more frequent designation. Arte joven ("young art) in Spain, Arte nuova ("new art") in Italy, and Nieuwe kunst ("new art") in the Netherlands, модерн ("new", "contemporary") in Russia - all continue this theme. In similar manner, its modern characteristics gave way to the label of Catalan Modernisme in Barcelona. Many names refer specifically to the organic forms that were popular with the Art Nouveau artists: Stile Floreal ("floral style"), Lilienstil ("lily style"), Style Nouille ("noodle style"), Stile Vermicelli ("vermicelli", or "little worm noodle" style), Bandwurmstil ("tapeworm style"), Paling Stijl ("eel style"), and Wellenstil ("wave style").
In other cases, important examples, well-known artists, and associated locations influenced the names. Hector Guimard's Paris Métro entrances, for example, provided the term Style Métro, the popularity in Italy of Art Nouveau designs from London's Liberty & Co department store resulted in its being known as the Stile Liberty ("Liberty style"), and, in the United States, it became known as the "Tiffany style" due to its connection to Louis Comfort Tiffany. In Austria, a localized form of Art Nouveau was practised by artists of the Vienna Secession, and it is, therefore, known as the Sezessionstil ("Secession style"). As a stand-alone term, however, "Secession" (German: Sezession, Hungarian: szecesszió) is frequently used to describe the general characteristics of Art Nouveau style beyond Vienna, but mostly in areas within the cultural reach of Austria-Hungary at the turn of the 20th century. In the United Kingdom, it is associated with the activities of Charles Rennie Mackintosh in Glasgow, and is often known as the "Glasgow" style.
Art Nouveau tendencies were also absorbed into larger local movements. In Denmark, for example, it was one aspect of Skønvirke ("aesthetic activity"), which itself more closely relates to the Arts and Crafts Movement. Likewise, artists adopted many of the floral and organic motifs of Art Nouveau into the Młoda Polska ("Young Poland") movement in Poland. Młoda Polska, however, was also inclusive of other artistic styles and encompassed a broader approach to art, literature and lifestyle.
