frjálsir
Frjálsir is an Icelandic term that can refer to more than one thing, and there isn’t a single widely recognized entity by that exact name. To write a precise wiki-style article, could you specify which use you have in mind (for example a sports club, a political or social group, a musical act, or simply the linguistic meaning of the term)? If you’d like, I can also provide a short general disambiguation-style entry describing the different possible uses.
