Rumination
noun /ˌruːmɪˈneɪʃən/ — The mental habit of replaying what went wrong.
Definition
The process of thinking deeply about something; in psychology, the compulsive, repetitive focus on distressing experiences or feelings.
Beyond the definition
Clinically distinct from reflection. Reflection is constructive — learning from experience. Rumination is the loop: replaying the argument, the mistake, the embarrassment until it's worn a groove in your thinking. Naming it is the first step to interrupting it.
Origin & history
From Latin ruminare — to chew the cud. Cows chew, swallow, regurgitate, and chew again. The mind does this too.

Rumination vs reflection
Reflection is constructive — thinking back in order to learn, integrate, or improve. Rumination is the same activity turned destructive: the same experience replayed on a loop without resolution, wearing a groove in the mind rather than generating insight. You can choose to reflect; rumination happens to you. Reflection ends when you've understood something; rumination has no natural stopping point.
