Smoldering
adjective /ˈsmoʊl.dər.ɪŋ/ — A slow-burning, intense quality of suppressed desire.
Definition
Showing or characterized by a slowly burning, intense, and largely suppressed emotion — particularly desire, anger, or passion. Smoldering suggests something contained rather than expressed: the heat held in rather than released, which makes it more, not less, intense.
Beyond the definition
Smoldering desire is desire that has been disciplined into intensity — the felt sense of something held just below the surface, more present for being restrained. It is the opposite of explosion; it is sustained heat.
Origin & history
From 'smolder' (to burn slowly and without flame); from Middle English 'smoldren'. The figurative use for suppressed passion developed in 19th century romantic literature.
