An astrologer is an individual who practices astrology, the study of the movements and relative positions of celestial bodies interpreted as having an influence on human affairs and the natural world. The term is derived from the Greek word astrologia, which literally translates to "the speech of the stars." In Hebrew, an astrologer is known as מַזָּלָן (mazzalán), while in Spanish, the term is astrólogo, and in French, it is astrologue. Astrologers often create horoscopes, which are forecasts of a person's future based on the positions of the Sun, Moon, and planets at the time of their birth. The practice of astrology is distinct from astronomy, which is the scientific study of celestial objects and phenomena. Astrologers may use various systems, such as Western tropical astrology, Vedic astrology, or Chinese astrology, each with its own set of traditions and methods. Throughout history, astrology has been used for divination, as a guide for decision-making, and as a tool for understanding personality traits and life events.
