UK[ˈɔːrə]US[ˈɔːrə]

Etymology
The word 'aura' entered English in the late 14th century, directly from Latin, where it meant "a breeze, a breath of air." The Latin term was itself borrowed from the Greek word 'αὔρα' (aura), which carried the same literal meaning of "breeze, breath, wind." This Greek root is thought to derive from the Proto-Indo-European base awer-, related to blowing and air. The semantic evolution from a tangible "breeze" to an intangible "atmosphere" or "emanation" is a classic example of metaphorical extension, where a physical phenomenon is used to describe a subtle, immaterial presence. The medical sense, referring to a premonitory sensation, developed in the 19th century, further abstracting the concept to an internal, subjective experience that "surrounds" an event.
