To include in a schedule; to schedule or put on a timetable.
From en- + schedule, where schedule comes from Latin schedula (small piece of paper). The verb means to place something into a formal schedule or plan.
This bureaucratic-sounding word is a perfect example of how en- verbs were formed productively in English—once schedule existed as a noun, speakers could simply add en- to make it a verb, much like how we'd say 'to calendar' something today.
