means The gravitationally bound neighborhood of roughly 100 galaxies — dominated by the Milky Way and Andromeda — that we call cosmically local.

from Astronomers simply named it for what it is: the group of galaxies local to us, coined in the early 20th century as telescopes resolved individual 'spiral nebulae' into actual separate galaxies. Once it became clear the Milky Way wasn't alone but had neighbors — the Magellanic Clouds, Andromeda, and a crowd of smaller dwarfs — astronomers needed a term for 'our' cluster as distinct from the countless other galaxy groups and clusters scattered across the universe. No myth, no borrowed word — just plain descriptive naming, the same instinct that gives us 'Local Bubble' or 'Local Supercluster.'
