Multilocale

Multilocale is an adjective and noun used to describe something that spans or operates across multiple geographic locations. In common usage, it denotes arrangements, practices, or systems that involve more than one locality.

In computing and software development, multilocale (or multilocale support) refers to applications that adapt content to several locales. This includes language translation, regional formats for dates and numbers, currency, and culturally specific conventions. Multilocale systems rely on locale identifiers and are a core aspect of internationalization (i18n) and localization (L10n).

In human geography and sociology, multilocale living describes patterns in which a person or household maintains residences in two or more locations, often for work, family, education, or climate-related reasons. This mobility influences housing choices, consumption, and access to services, and may involve recurring visits, seasonal stays, or long-term dual residences.

In sociolinguistics and language studies, multilocale language use refers to the adjustment of speech practices across locales, including shifts in vocabulary, pronunciation, and code-switching according to social networks and place-based norms.

Notes: The term is used variably across disciplines and does not designate a single entity. Related concepts include localization, internationalization, mobility, and diaspora.
