There are also a number of masculine nouns borrowed intact from Italian, with a final "-o", like "treno" (train). Many of the words have been fully absorbed into the language and even form their plurals with the regular Friulian "-s" rather than the Italian desinence changing. Still, there are some purists, including those influential in Friulian publishing, who frown on such words and insist that the "proper" Friulian terms should be without the final "-o". Despite the fact that one almost always hears "treno", it is almost always written "tren".
