Eponyms
Several plants were named after Freyja, such as Freyja's tears and Freyja's hair (Polygala vulgaris), but during the process of Christianization, the name of the goddess was replaced with that of the Virgin Mary. In the pre-Christian period, the Orion constellation was called either Frigg's distaff or Freyja's distaff (Swedish Frejerock).
Place names in Norway and Sweden reflect devotion to the goddess, including the Norwegian place name Frøihov (originally *Freyjuhof, literally "Freyja's hof") and Swedish place names such as Frövi (from *Freyjuvé, literally "Freyja's vé"). In a survey of toponyms in Norway, M. Olsen tallies at least 20 to 30 location names compounded with Freyja. Three of these place names appear to derive from *Freyjuhof ('Freyja's hof'), whereas the goddess's name is frequently otherwise compounded with words for 'meadow' (such as -þveit, -land) and similar land formations. These toponyms are attested most commonly on the west coast though a high frequency is found in the southeast.
Place names containing Freyja are yet more numerous and varied in Sweden, where they are widely distributed. A particular concentration is recorded in Uppland, among which a number derive from the above mentioned *Freyjuvé and also *Freyjulundr ('Freyja's sacred grove'), place names that indicate public worship of Freyja. In addition, a variety of place names (such as Frøal and Fröale) have been seen as containing an element cognate to Gothic alhs and Old English ealh ('temple'), although these place names may be otherwise interpreted. In addition, Frejya appears as a compound element with a variety of words for geographic features such as fields, meadows, lakes, and natural objects such as rocks.
The Freyja name Hörn appears in the Swedish place names Härnevi and Järnevi, stemming from the reconstructed Old Norse place name *Hörnar-vé (meaning "Hörn's vé").
