Thus Oxford Dictionaries Online defines the term as 'a taxonomic name which has the same application as another, especially one which has been superseded and is no longer valid.' In handbooks and general texts, it is useful to have synonyms mentioned as such after the current scientific name, so as to avoid confusion. To the general user of scientific names, in fields such as agriculture, horticulture, ecology, general science, etc., a synonym is a name that was previously used as the correct scientific name (in handbooks and similar sources) but which has been displaced by another scientific name, which is now regarded as correct. has been rejected in favour of Erica carnea L. Synonyms also come about when the codes of nomenclature change, so that older names are no longer acceptable for example, Erica herbacea L. They may also arise when existing taxa are changed, as when two taxa are joined to become one, a species is moved to a different genus, a variety is moved to a different species, etc. Synonyms may arise whenever the same taxon is described and named more than once, independently. 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). A synonym cannot exist in isolation: it is always an alternative to a different scientific name.

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). In taxonomy, synonyms are not equals, but have a different status. Unlike synonyms in other contexts, in taxonomy a synonym is not interchangeable with the name of which it is a synonym. However, Araschnia levana is not a synonym of Papilio levana in the taxonomic sense employed by the Zoological code. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank – for example, the name Papilio prorsa Linnaeus, 1758 is a junior synonym of Papilio levana Linnaeus, 1758, being names for different seasonal forms of the species now referred to as Araschnia levana (Linnaeus, 1758), the map butterfly.

In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym.

This name is no longer in use, so it is now a synonym of the current scientific name, Picea abies. 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. In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name.The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently.
