Gender

This page reviews the historical origins and evolution of the term gender.

Etymology and early usage

The English word gender entered the language around the early 14th century, derived from Old French gendre / genre, which in turn came from the Latin word genus, meaning kind, type, or class 1.

In Latin usage, genus encompassed both broad classification and distinctions related to biological sex, including male and female categories. The word was also used by Roman grammarians to translate Aristotle’s Greek term genos, which referred to natural groupings 1 2.

Grammatical meaning

The earliest English uses of gender primarily referred to grammatical gender. In this context, nouns were classified as masculine, feminine, or neuter, following patterns inherited from Latin and other Indo‑European languages 3 4.

These grammatical categories were originally modeled on biological sex distinctions, even though they were often applied metaphorically to inanimate objects. Early grammar texts defined gender as a linguistic distinction reflecting male, female, or neither categories 3.

Gender as biological sex

By the 15th century, gender was also commonly used in English to refer directly to biological sex. Terms such as male gender and female gender appeared in both literary and descriptive texts, functioning as near‑synonyms for sex 1 5.

This usage persisted for centuries. Pre‑modern dictionaries and reference works did not distinguish meaningfully between sex and gender when referring to humans or animals.

As an example, Webster’s Dictionary (1828) defined gender primarily as:

“A sex, male or female,”
with grammatical usage listed as a secondary meaning 6.

Shift in modern usage

The conceptual separation of sex and gender is a comparatively recent development in the history of the English language.

Before the mid‑20th century, the word gender overwhelmingly referred either to grammatical classification or to biological sex. The use of gender to describe an individual’s internal identity or social role emerged primarily in academic contexts during the 1950s and 1960s, particularly within psychology and sociology 1 7.

Even modern reference works acknowledge that this identity‑based meaning represents a departure from historical usage. Prior to this period, such usage was rare or absent from standard English references 7.
