adjective /ˈsməʊl.dər.ɪŋ/ — Burning slowly; suppressed intensity or passion
Definition
Burning slowly without flame — or of a person, showing suppressed anger, passion, or desire that is all the more powerful for not being openly expressed.
Beyond the definition
The intensity that never quite ignites. A smoldering look, a smoldering grievance — both suggest something that has been burning for a long time and has not finished.
