leadup

Lead-up, also written as lead-up or leadup, is a noun that refers to the period or sequence of events that precedes a significant occurrence. It denotes the buildup, preparations, discussions, or announcements that shape expectations for the upcoming event. The term can function as an adjective in phrases such as lead-up activities or lead-up coverage. Etymologically, it derives from lead with the sense of bringing forward or guiding toward a objective, joined with up to indicate forward movement toward the event; usage has varied with hyphenation over time.

In journalism, politics, sports, and business, the lead-up to an event describes the months, days, or moments before it, including campaigns, previews, tests, and media coverage. Examples include the lead-up to an election, the lead-up to a product launch, or the lead-up to a championship final. The concept emphasizes preparation and anticipation rather than the event itself, and the tone may be neutral, positive, or critical depending on the context.

Related terms include buildup or buildup period, lead time, and precursor, each carrying slightly different emphases. The noun form lead-up is common in British and Commonwealth English; American usage often adopts leadup or lead-up with similar meaning, though hyphenation remains preferred in formal writing.
