Schedule: which option best defines its noun use?

• A. To arrange for something; to make arrangements
• B. To plan for something
• C. To make plans
• D. A timetable of events with times

Answer: (D)

Schedule has two uses: as a noun, it names a fixed plan or timetable that lists events with their times; as a verb, it means to arrange or plan those times. The noun use is captured by describing it as a timetable of events with times, like a class or bus schedule you consult for when things happen. The other options describe actions you take with plans—to arrange, to plan, or to make plans—which are verb senses, not the listing itself.
