Common Mistakes

This sense describes sudden explosive anger, not a general personality trait.

Synonym discussion

Sense: adjective/2

All three words describe intense anger, but each carries a different shade of meaning. 'Explosive' (the closest synonym) emphasises the sudden, violent release of emotion — someone with an explosive temper can seem calm one moment and furious the next, just like a volcanic eruption. 'Fiery' suggests a more continuous, passionate heat; a fiery person may argue with energy and intensity, but not necessarily without warning. 'Volatile' focuses on unpredictability — a volatile temperament can shift from calm to rage quickly, but the word also describes unstable situations beyond personal anger. Use 'volcanic' when you want the strongest visual metaphor: anger that builds underground pressure and then erupts with destructive force. For example: 'His volcanic rage shocked the whole team' sounds far more violent than 'his fiery disagreement'. Choose 'explosive' for suddenness, 'fiery' for passion, 'volatile' for instability, and 'volcanic' when you want the full force of the eruption metaphor.

Etymology

LatinItalianFrenchEnglish

From French 'volcanique', from Italian 'vulcanico', from Latin 'Vulcānus' — the name of the Roman god of fire and metalworking. The literal meaning ('related to a volcano') entered English in the 1570s. The figurative sense ('explosively angry') developed in the late 1700s, drawing a comparison between a person's sudden rage and a volcano's eruption.
