What does Aquarius mean?

Aquarius is the name of a constellation that is interpreted as resembling a person carrying a bucket of water. It is sometimes called the Water Bearer or the Water Carrier.

A constellation is a group of stars that appear near each other in the sky—especially a group that has been given a name. Aquarius is considered one of the 12 zodiacal constellations—constellations that appear within a particular portion of the sky called the zodiac.

In astronomy, the zodiac is the band of sky along which the paths of the sun, the moon, and the planets appear to move.

Despite its basis in astronomy, the word zodiac is mainly associated with and most often used in the context of astrology, the nonscientific practice in which the positions of heavenly bodies at certain times are thought to influence or be correlated with human behavior and events. In astrology, zodiac refers to a diagram (often a circular one) representing the zodiac belt and showing the symbols associated with each of the 12 constellations or sections, which are called the signs of the zodiac. Aquarius is one of these signs. It is situated between Capricorn and Pisces and is considered the eleventh sign of the zodiac.

The other signs of the zodiac are Aries, Taurus, Gemini, Leo, Cancer, Virgo, Libra, Scorpio, and Sagittarius.

The position of the sun in a particular portion of the zodiac at the moment of a person’s birth is thought to correlate with their personality. This is what people are referring to when they talk about their zodiac sign (or star sign or often just sign). People whose sign is Aquarius are those born between January 20 and February 18.

The word Aquarius can be used as a noun to refer to someone who is born during this time, as in I was born in early February, so I’m an Aquarius. The word Aquarian can be used to mean the same thing. It can also be used as an adjective form of Aquarius.

Example: The constellation Aquarius is one of the largest in the sky.

Aquarius dates

People with the sign Aquarius are traditionally considered to be those born in the range of January 20–February 18. However, interpretations vary.

Where does Aquarius come from?

The first records of the word Aquarius in English come from around 1400. The word is taken directly from Latin, in which it means “water carrier,” from the Latin root aqua, meaning “water.”

In astrology, the different signs of the zodiac are thought to be associated with certain personality traits. Traits associated with Aquarius include creativity and confidence. Aquarius and the other signs of the zodiac are often used in the context of a person’s horoscope. The word horoscope can refer to a diagram of the heavens that maps the relative position of planets and the signs of the zodiac. It can also refer to a prediction based (or said to be based) on a person’s sign and the location of other celestial bodies at the time they were born.

The term age of Aquarius is used in the context of astrology to refer to an era believed to bring increased spirituality and harmony in the world. Things associated with or related to this can be described as Aquarian.
