What does allotype mean?
Allotype is a specialist noun used in two related technical fields. In taxonomy, it refers to a specimen designated as a secondary type, usually to supplement the holotype and often to represent the opposite sex. In sociolinguistics, it describes a form of a linguistic variable that is associated with a particular social group or social context. For example, different forms of a sound or grammatical construction may be described as allotypes when their use varies systematically across groups of speakers. The word is not normally used in general conversation, and its occurrence usually signals discussion of scientific classification or detailed language variation. Its structure reflects this meaning: “allo-” refers to something other or different, while “-type” refers to a model, form, or kind. The term is useful when precision matters, especially when a primary type specimen needs additional documentation or when linguists describe patterned variation in speech.
nounIn taxonomy, an allotype is a specimen designated as a secondary type in a species or subspecies type series, often chosen to represent the opposite sex from the holotype. In sociolinguistics, an allotype is a form of a linguistic variable associated with a particular social group or social context.
- A specimen designated as a secondary type in a taxonomic type series, often chosen to represent the opposite sex from the holotype.
- In sociolinguistics, a form of a linguistic variable associated with a particular social group or social context.
"The museum designated a male specimen as the allotype, supplementing the female holotype."
"The museum designated a male specimen as the allotype, supplementing the female holotype."
"The researcher analyzed different allotypes of the variable, including forms used by younger and older speakers."
"The allotype was selected from the type series to represent the sex opposite the holotype."
The standard plural is allotypes.
"The researchers compared several allotypes of the variable across different social groups."
Allotype literally means “other type”: it is the supporting specimen that helps anchor a scientific name when the holotype alone is not enough.

Where does allotype come from?
The word combines Greek allos, meaning “other,” with types or typos, meaning “model” or “type,” through the same classical roots found in English type. Its taxonomic sense developed as nomenclature required distinctions among the primary holotype and other designated specimens. Sociolinguists later applied the related idea of a distinct “other type” to forms of linguistic variables associated with social groups.

How allotype is actually used
Allotype is a highly specialized, formal term rather than an everyday word. Its taxonomic use is most common in zoological nomenclature, while its linguistic use appears mainly in sociolinguistic and variation-based analysis.
Easily confused with allotype
A holotype is the single specimen designated as the primary name-bearing type of a taxon, whereas an allotype is a secondary type selected to supplement it.
An allotype is a socially patterned linguistic form or a secondary taxonomic specimen, while an allograph is a variant form of a written grapheme or sign.
