Definition of Mutable Sign
Mutable Signs (Gemini, Virgo, Sagittarius, Pisces) are the most flexible signs in the zodiac. They go whichever way the wind is blowing, and are always subject to change.
The word mutable literally means “subject to change”, compared to Fixed Signs, which are always fixated, and Cardinal Signs, which take charge.
People with Zodiac signs in the Mutable category will drop everything when you need them. This is a double-edged sword, as it applies to others, as well. Mutable signs are usually the first to be unfaithful or deceptive, unless you’re able to create a supportive existence with mutual understanding.
