Morphology

milky + way

The phrase literally combines 'milky' (milk-like) and 'way' (path), so a B1 learner who knows both words can infer it refers to a pale, band-like path — i.e. a milky-looking feature in the sky. However, the specific astronomical sense as the name of our galaxy (containing the solar system) is a conventionalized, proper-name meaning that goes beyond the simple literal composition and may not be fully predictable without prior exposure.

Etymology

Milky Way may come from the way the bright band across the night sky looks like spilled milk, so people thought of a milky 'road' or way in the sky. One popular story says the Greek goddess Hera's milk spilled across the sky, and that image explains why the name now means the galaxy we see as a bright band of stars.
