Synonym discussion

Sense: noun/2

Bombshell, shock, thunderbolt, bolt from the blue, and surprise all refer to something unexpected, but they differ greatly in intensity and register. Thunderbolt and bolt from the blue are the most vivid — both suggest an event so sudden that it completely changes one's understanding of a situation, with 'bolt from the blue' adding the image of a cloudless sky to emphasise the total lack of warning. Bombshell is similar in intensity but is more common in news headlines and gossip contexts ('the bombshell revelation'). Shock is the broadest term, covering everything from mild surprise to deep emotional trauma. Surprise is the mildest and most neutral — receiving a gift can be a pleasant surprise but never a thunderbolt. In everyday speech, thunderbolt is far less common than shock or surprise; it belongs to writing, news reporting, and fixed expressions like 'came as a thunderbolt.'

Etymology

Germanic (Old English)English

Thunderbolt is a compound of two Old English words: 'thunder' (þunor — the loud sound from a storm) and 'bolt' (bolt — a short, heavy arrow). In ancient mythology, people believed that thunderbolts were arrows or weapons thrown across the sky by angry gods — the Greek god Zeus and the Norse god Thor were both said to hurl thunderbolts at their enemies. Over time, the word lost its mythical meaning and came to describe the natural phenomenon of lightning striking the earth with a crash of thunder.
