Locales

noun

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. 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. 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.)
