What is "cardinal sign"

This article is about the zodiac signs. For the five cardinal signs of inflammation, see Inflammation#Clinical_signs.

In astrology, cardinal signs (also called by older astrologers a moveable sign) are associated with being active, self-motivated, ambition and dynamic qualities that initiates a change. They can be bossy, opinionated, inconsiderate and domineering.

The word "cardinal" originates from the Latin word for "hinge," since they each mark the turning point of a temperate season. They were called moveable by traditional astrologers because, as Bonatti says, the "air" changes when the Sun enters each of these signs, bringing a change of season. Sometimes the word cardinal is confused with the word angular. Angular signs are those signs which are located on the astrological angles of any given natal chart. Angular houses may be cardinal, fixed or mutable, depending on the birth time of the chart, but only Aries, Cancer, Libra, and Capricorn are cardinal signs.

The four cardinal signs of the Zodiac are:

• Aries : the Sun's passage through which begins the spring in the northern hemisphere, and autumn in the southern hemisphere.
• Cancer : which begins the summer in the northern hemisphere, and winter in the southern hemisphere.
• Libra : which begins the autumn in the northern hemisphere, and spring in the southern hemisphere.
• Capricorn : which begins the winter in the northern hemisphere, and summer in the southern hemisphere.

Cardinal sign may refer to:

• Cardinal sign (astrology)
• Cardinal sign (pathology)

In pathology, a cardinal sign or cardinal symptom is the primary or major clinical sign symptom by which a diagnosis is made.

A cluster of signs or symptoms are often combined ( pathognomonic) to better diagnose a specific disease or syndrome.
