scheduled

The word “scheduled” means planned to happen at a set time. In plain terms, already planned for a specific time.

Here is “scheduled” used in a sentence: “The scheduled flight was delayed by two hours.”

“Scheduled” is an adjective.

“Scheduled” is a fairly common word in modern English, usually learned at around the B2 level.

There are two accepted pronunciations. British English typically says 'SHED-yoold,' while American English says 'SKED-joold.' Both are correct and refer to the same word; the difference is purely regional, stemming from whether the 'sch' is sounded in the French-influenced or the Greek-influenced way.

Scheduled means planned to happen at a fixed, agreed time, like a scheduled flight or meeting. Unscheduled is the opposite: happening without prior planning or outside the set timetable, such as an unscheduled stop. The key idea is whether the event was arranged in advance or occurred unexpectedly.

You might say, 'The train is scheduled to depart at nine o'clock,' meaning its departure is planned for that set time. Other everyday examples include a scheduled appointment, a scheduled maintenance window, or a scheduled release date. In each case, something is fixed to occur at a particular moment.
