I wonder what the word "Star" in Star Wars refers to. Why did George Lucas choose this title for his epic? The word "Wars" is clear, but I don't know what "Star" refers to. Does anyone know?
In case it's not clear, a star (in this context) is:
- Any small luminous dot appearing in the cloudless portion of the night sky, especially with a fixed location relative to other such dots.
- (astronomy) A luminous celestial body, made up of plasma (particularly hydrogen and helium) and having a spherical shape. Depending on context the sun may or may not be included.
The literal meaning of the title could be interpreted as "A series of wars among the stars". "Among the stars" is a turn of phrase used to mean "out in space".
Compare with the title Star Trek, which means "a journey (trek) among the stars".
Also compare with the TV show Star Search, which means "a search for stars". In this case, "stars" means people who will become famous, not large balls of hydrogen fusion in space, but the grammar of the title is the same.
In general, an English construction of noun verb often means, "doing verb in the context of noun". For example, sea trade is the trading of goods using ocean vessels. Shore leave means "a break from service that takes place on dry land (not at sea)". Space walk means "an excursion from a spacecraft wearing only a spacesuit or EVA suit" - in other words, "a walk in space".
