þrívíðra
þrívíðra is the genitive plural form of the Icelandic word "þrívíður." "Þrívíður" translates to "three-footed" or "tripedal" in English. Therefore, "þrívíðra" refers to "of the three-footed ones" or "belonging to the three-footed things." This grammatical form is used when discussing multiple entities that possess three feet or legs, or when describing something in relation to them. For example, in a sentence discussing the anatomy of a mythical creature with three legs, one might use "þrívíðra" to indicate possession or association with these creatures. The term is primarily encountered in contexts related to Icelandic language, literature, or discussions of zoology or mythology where such a characteristic might be relevant. Understanding this genitive plural form is essential for correctly interpreting Icelandic sentences that refer to a group of three-footed subjects or objects.
