The Sanguine temperament has three combinations: Sanguine-Choleric, Sanguine-Phlegmatic, and Sanguine-Melancholic.
The traits of the primary temperament, Sanguine, may be altered or modified in some significant way due to the influence of the secondary temperament. Remember, there are at least three levels of intensity of a temperament: classic, moderate, and mild. Some Sanguines will be very strong, others somewhat strong, and still others more mild. Some are “Super Sanguines” because they are so talkative and active that they can be overwhelming.
Sanguine is traditionally understood as being fundamentally stable (defined as "weak emotions") and extraverted (defined as "short-lasting emotions").
