Journalism is rich in jargon. Some of it comes from printing (book for magazine); or survives from the pre-computer age (spike for rejected copy); or is imported from the United States (clippings for cuttings). It is often punchy and graphic (ambush, bust, fireman). But if it crops up in copy (eg in stories about the media) the sub will usually have to change it (replace ‘story’ by ‘report’) or explain it (after ‘chapel’ insert ‘office branch’ in brackets). The obvious exception is in publications for journalists such as Press Gazette and the Journalist.
