### Noun

locale (plural locales)

1. The place where something happens.
Being near running water and good shade, the explorers decided it was a good locale for setting up camp.
2. (computing) The set of settings related to the language and region in which a computer program executes. Examples are language, currency and time formats, character encoding etc.
3. (mathematics) A partially ordered set with the following additional axiomatic properties: any finite subset of it has a meet, any arbitrary subset of it has a join, and distributivity, which states that a binary meet distributes with respect to an arbitrary join. (Note: locales are just like frames except that the category of locales is opposite to the category of frames.)
• 2011 June 27, Tom Leinster, “An informal introduction to topos theory”, in arXiv.org[1], Cornell University Library, retrieved 2018-3-21:
Since every locale is of the form ${\displaystyle {\mbox{Sub}}_{\mathcal {E}}(1)}$ [subobjects of the terminal object in ${\displaystyle {\mathcal {E}}}$] for some topos ${\displaystyle {\mathcal {E}}}$, locale theory can be regarded as the fragment of topos theory concerning subobjects of 1. A subobject of 1 is a map ${\displaystyle 1\rightarrow \Omega }$, which can reasonably called a truth value. In that sense, locale theory is the study of truth values.
