unilingually

Unilingually is an adverb meaning in a single language; without the involvement or inclusion of other languages. It is used to describe content, communication, or contexts that are not multilingual.

The word is formed from unilingual (an adjective meaning "in one language") plus the suffix -ly to create an adverb. The term is relatively rare in everyday speech and is more likely to appear in linguistic, bibliographic, or editorial writing. In many cases, speakers choose simpler phrasing such as "in English only" or "monolingually."

Examples include: The software interface was released unilingually in Japanese; the conference proceedings were distributed unilingually, with no translations provided. A website might remain unilingually accessible if it is not translated into other languages. In education or publishing, a decision to present material unilingually often reflects the intended audience and resource considerations.

Distinction: unilingually refers to the nature of content or discourse, not to the language ability of individuals. It is different from monolingual, which can describe a person who uses only one language; and from bilingual or multilingual, which describe contexts or abilities involving more than one language.

Related terms include unilingual, monolingual, bilingual, multilingual, and polyglot.
