rage

Rage entered English from Old French rage (fury, madness, rabies), from Late Latin rabia, a variant of Latin rabies (madness, fury, frenzy), from rabere (to rave, to be mad). The Latin word rabies applied equally to the disease transmitted by animal bites and to states of extreme human anger. The Romans did not distinguish clearly between the two — both were forms of madness, loss of reason, the human becoming animal.

In medieval French, rage kept both meanings. A person in rage was either furious or rabid, and the word treated both conditions as related. The English borrowing, arriving after 1066, gradually separated the meanings. 'Rage' became the emotion. 'Rabies' (borrowed directly from Latin much later, in the sixteenth century) became the disease. But the underlying metaphor persists: rage is a kind of infection that makes you something other than yourself.

The phrase 'all the rage' — meaning extremely fashionable — appeared in the eighteenth century and seems to contradict the word's violent origins. But it preserves an older sense of rage as an overwhelming, consuming force. A fashion that is all the rage has taken over, spread uncontrollably, become a kind of mania. The metaphor of contagion holds.

Road rage entered English in 1988, coined by a Los Angeles television station. The compound became instantly recognizable because rage, as a suffix, communicates something specific: not ordinary anger but a sudden, disproportionate fury triggered by circumstance. Air rage, desk rage, parking rage — the word now attaches to any situation that produces irrational wrath. The Latin rabies is still in there, frothing.
