the scoop
Synonym discussion
Sense: idiom/1
All four phrases refer to information that is not yet widely known, but they differ in register and nuance. 'The scoop' is distinctly informal and often carries a journalistic or gossipy tone — think of a reporter breaking a story or a friend sharing juicy news. 'Inside information' is more neutral and formal; it suggests access to a privileged source and is common in business or legal contexts. 'The lowdown' is very casual and focuses on the practical, essential facts someone needs to know ('give me the lowdown on the new boss'). 'The inside story' implies a fuller narrative or backstory rather than a single fact. For everyday gossip, 'the scoop' fits best; for a boardroom leak, 'inside information' works better; for a friend's quick summary, use 'the lowdown'; and for a detailed behind-the-scenes account, choose 'the inside story'.
Etymology
The idiom 'the scoop' draws on the journalistic sense of 'scoop', which dates back to the late 1800s in American newspapers. A reporter who 'scooped' the competition got the story published first. By the early 1900s, 'the scoop' had broadened from a breaking-news exclusive to any piece of interesting inside information, even in casual conversation.
