fire-breathing

The compound "fire-breathing" is a modern English formation, transparently combining two native Germanic elements. The first element, "fire," descends from the Proto-Germanic fōr, a word of immense primal significance. The second, "breathing," originates from the Old English brǣþ, meaning "odor" or "vapor," which evolved to describe the act of respiration. The compound's literal sense, describing mythical beasts like dragons, directly visualizes the act of expelling breath as flame. This vivid imagery was later extended metaphorically to describe people exhibiting intense, fiery aggression or zeal, completing the word's journey from a concrete mythological description to an abstract characterization of temperament.

Structure: fire + breathing - fire: From Old English 'fȳr', of Germanic origin; related to Dutch 'vuur' and German 'Feuer'. Functions as a noun used attributively to modify the second element. - breathing: From Old English 'brǣþ' (odor, scent, exhalation) and the verb-forming suffix '-ing', from the present participle of 'breathe'. Functions as a verb-derived adjective meaning "the act of expelling air from the lungs".
