What does gemini mean?
Gemini is the third sign of the zodiac, traditionally associated with people born between approximately May 21 and June 20. It takes its name from the twins Castor and Pollux, whose story comes from Greek mythology and who are represented by the constellation Gemini. In ordinary modern usage, the word can refer either to the sign itself or to an individual born under it. Descriptions of Geminis often emphasize qualities such as curiosity, adaptability, sociability, and a tendency to have many interests, although such characterizations belong to astrology rather than scientifically established traits. The name also has an important technological history: NASA's Project Gemini was the United States' crewed spaceflight program between Mercury and Apollo. An older and now mainly literary use of Gemini simply means twins. The word is memorable because it links ideas of duality, identity, communication, and twin journeys across astrology, mythology, astronomy, and space exploration.

Etymology of gemini
Gemini comes through Latin, where geminus means “twin” and Gemini is its plural form. The name was applied to the mythological twins Castor and Pollux and was subsequently used for the zodiac sign and the constellation containing their stars. Project Gemini also took its name from this tradition, with its paired spacecraft reinforcing the association with twins.
How gemini is actually used
Gemini is usually capitalized in modern English, particularly when referring to the zodiac sign, the constellation, the mythological twins, or the space program. Its use in astrology is conventional and cultural rather than scientific. The older sense meaning twins is now chiefly literary or archaic.
