Emotions are an essential part of who you are, but they can be messy, complicated, and downright confusing sometimes. Knowing how to name them and talk about them — with both yourself and others — is a key part of developing emotional health.

Fortunately, you don’t have to navigate the process of identifying your emotions alone. Paul Ekman, a psychologist and leading researcher on emotions, surveyed more than 100 scientists and used their input to develop what’s known as the Atlas of Emotions.

Breaks down of emotions into five main categories:

  • anger
  • fear
  • sadness
  • disgust
  • enjoyment

Keep in mind that this is just one way of categorizing emotions. For example, a recent study suggests that there are 27 categories of emotion. But Ekman’s concept of five main types of emotion offers a good framework for breaking down the complexity of all the feels.

Here’s a look at what each of these five categories involves.
