genius loci (plural genii loci or genii locorum)

1. (Roman mythology) The minor deity or spirit watching over a particular place.
2. (figuratively) The spirit or atmosphere of a place, especially conceived as a source of artistic inspiration.

In English, genius loci is often italicized as a Latin phrase. It employs the Latin nominative plural but is usually not otherwise grammatically declined. The plural form genii loci describes multiple spirits overseeing a single place; the plural form genii locorum describes multiple spirits overseeing multiple places; and the latter should be confused with genius locorum, which describes a single spirit overseeing multiple places.

• (inspirational atmosphere): geist, muse, ambience

• See tutelary deity and Thesaurus:spirit

• genius locorum (overseeing multiple places)

• genius hominis (overseeing a person)
• genius familiae (overseeing a family)
