Question: What do the roots that the alternative name of a Haugtusse derive from mean?
Context: The Khurramites (Persian: خرمدینان‎ ‎ "Khorrām-Dīnān", meaning "those of the Joyful Religion"; Arabic: خُرَّمِيَة‎ ‎ "Khurramiyya") were an Iranian religious and political movement with its roots in the movement founded by Mazdak.  An alternative name for the movement is the "Muḥammira" (Arabic: محمرة‎ ‎ , "Red-Wearing Ones"; in Persian: سرخ‌جامگان‎ ‎ "Surkh-Jāmagān"), a reference to their symbolic red dress. Stauffer (also commonly spelled "Stouffer" and "Stover" in North America) is a German surname, the origin of which derives from the Proto-German word "staupa", meaning "steep."  "Staupa" and its Middle High German descendant, "stouf", evolved to mean, among other things, a steep hill or mountain.  Many of these hills and mountains serve as the basis for the names of such places as Donaustauf, Hohenstaufen, Staufenberg, Regenstauf, Staufen im Breisgau, and the Staufens of Switzerland and Austria.  Stauffer surnames derive from these hills.  The Swiss Mennonite Stauffers common in the U.S. and Canada derive their name from a hill called "Stouffe" or "Stauffenalp" just southwest of the town of Röthenbach im Emmental in Switzerland. Mumviri is a dialect of the Kamkata-viri Nuristani language spoken by perhaps 1,500 of the Mumo people of Afghanistan.  There are only slight differences to the Kata-vari, Mumviri has Kamviri phonetic features.  The most used alternative name is "Bashgali", which derive from Khowar. The Antarctic Circumpolar Current (ACC) is an ocean current that flows clockwise from west to east around Antarctica.  An alternative name for the ACC is the West Wind Drift.  The ACC is the dominant circulation feature of the Southern Ocean and has a mean transport of 100-150 Sverdrups (Sv, million m³/s), making it the largest ocean current.  More recent research even puts this number at over 173 Sv.  The current is circumpolar due to the lack of any landmass connecting with Antarctica and this keeps warm ocean waters away from Antarctica, enabling that continent to maintain its huge ice sheet. The Napoletana is a breed of domestic goat from the area south of Naples, in Campania in southern Italy.  It is raised on the slopes of Vesuvius, on the slopes of the Monti Lattari, and in the Agro Nocerino Sarnese which lies between them.  The origin of the breed is unknown.  It may derive from goats of African origin imported to the area in the early years of the twentieth century; the alternative name Torca Nera, "black Turkish goat", suggests an origin in the Mediterranean basin. In chemistry, a hydrochloride is an acid salt resulting, or regarded as resulting, from the reaction of hydrochloric acid with an organic base (e.g. an amine).  An alternative name is chlorhydrate, which comes from French.  An archaic alternative name is muriate, derived from hydrochloric acid's ancient name: muriatic acid. The cubic metre (in British English and international spelling as used by the International Bureau of Weights and Measures) or cubic meter (in American English) is the SI derived unit of volume.  Its SI symbol is m.  It is the volume of a cube with edges one metre in length.  An alternative name, which allowed a different usage with metric prefixes, was the stère, still sometimes used for dry measure (for instance, in reference to wood).  Another alternative name, no longer widely used, was the kilolitre. Fakenham Magna (or Great Fakenham) is a village and civil parish in the St Edmundsbury district of Suffolk in eastern England.  The meaning of the word '"Fakenham"' can be split into two: 'Faken' and 'ham', both of which derive from Old English.  The former refers to somebody by the name of 'Facca', with the latter meaning 'a village / a homestead', making the direct translation 'Facca's homestead'. " 'Magna"' translates from Latin as 'great', hence the alternative name of the village of 'Great Fakenham'.  During World War Two, however, the village was referred to as 'Little Fakenham', which was used to avoid confusion with the larger civil parish of Fakenham in Norfolk. Haugtussa (edited 1895) is an epic circle of poems, written by the Norwegian author Arne Garborg.  The poems are reckoned a classical example of Norwegian Neo-romanticism or Symbolism.  The themes of the poems are closely related to Garborg's rural background, and a number of supernatural beings, like the draug, the hulderpeople and other creatures, are involved.  A "Haugtusse" is originally a female subterrestrial (a Hulder), but in this story it is an eponym of the main character, a psychic young girl, usually called "Veslemøy".  In 1900 Garborg published a sequel, "I Helheim" ("In Hel"). A hulder is a seductive forest creature found in Scandinavian folklore.  (Her name derives from a root meaning "covered" or "secret".)  In Norwegian folklore, she is known as huldra ("the [archetypal] hulder", though folklore presupposes that there is an entire Hulder race and not just a single individual).  She is known as the skogsrå "forest spirit" or Tallemaja "pine tree Mary" in Swedish folklore, and ulda in Sámi folklore.  Her name suggests that she is originally the same being as the völva divine figure Huld and the German Holda.
