means A violent storm with strong winds, often rain, thunder, or snow — or, figuratively, any furious uproar or emotional outburst.

from From Latin 'tempestas,' meaning a season, a stretch of weather, or a storm — itself rooted in 'tempus,' time. So a tempest is, etymologically, a 'time' gone wild: weather that turned on you. It traveled through Old French 'tempeste' into English, and the storm-sense crowded out the calmer 'season' meaning along the way. The cousin 'temperate' shares that same 'tempus' family — a reminder that the same root gave us both the storm and the mildness it interrupts.
