seethe
UK: siːð | US: siːð
vi. 1. (of liquid) to bubble or boil violently
vi. 2. (of a person) to be intensely angry or agitated
vt. 3. to soak or saturate (archaic)
The word "seethe" traces back to Old English sēoþan, meaning "to boil." It originally described the violent bubbling of liquids, later metaphorically extending to emotional agitation. The modern spelling preserves the core morpheme "see-" (from sēoþ-), while the "-the" suffix marks its verbal form. This dual meaning—literal boiling and figurative anger—reflects the word’s vivid sensory-to-emotional evolution.
