Syn (goddess)
In Norse mythology, Syn (Old Norse "refusal") is a goddess associated with defensive refusal. Syn is attested in the Prose Edda, written in the 13th century by Snorri Sturluson; and in kennings employed in skaldic poetry. Scholars have proposed theories about the implications of the goddess.
Attestations
In chapter 35 of the Prose Edda book Gylfaginning, High provides brief descriptions of 16 ásynjur. High lists Syn eleventh, and details that she "guards the doors of the hall and shuts them against those who are not to enter". High additionally states that Syn is "appointed in defense" at things "in legal matters in which she wishes to refute" and that her name is connected to a saying where "a denial (syn) is made when one says no."
In the Prose Edda book Skáldskaparmál, Syn is included among a list of 27 ásynjur names. Syn also appears in two kennings used in works recorded in Skáldskaparmál; once for "jötunn" ("hearth-stone-Syn") in Þórsdrápa by Eilífr Goðrúnarson, and for "woman" ("Syn [woman] of soft necklace-stand [neck]") in a work attributed to Steinar.
Synonym (taxonomy)
In scientific nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name, although zoologists use the term somewhat differently. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called Pinus abies. This name is no longer in use: it is now a synonym of the current scientific name which is Picea abies.
Unlike synonyms in other contexts, in taxonomy a synonym is not interchangeable with the name of which it is a synonym. In taxonomy, synonyms are not equals, but have a different status. For any taxon with a particular circumscription, position, and rank, only one scientific name is considered to be the correct one at any given time (this correct name is to be determined by applying the relevant code of nomenclature). A synonym is always the synonym of a different scientific name and cannot exist in isolation. Given that the correct name of a taxon depends on the taxonomic viewpoint used (resulting in a particular circumscription, position and rank) a name that is one taxonomist's synonym may be another taxonomist's correct name (and vice versa).
