I am thinking it is both.
If I am just an angry person, I could consider that anger is a primary emotion. But, if I am angry about another emotion, then anger is secondary. For example, I could feel guilty (primary) that I am a failure, and that may make me angry (secondary).
It makes a difference when, on the road to managing our emotions, we try to understand them. The best way to understand an emotion is to determine if it is a primary emotion (one that is a reflection on ourselves) or a secondary emotion (an emotion due to a primary emotion). If we can nail that down, we will better understand our emotions which will prepare us to manage our emotions.
