Definition of the word pencil in

The phrase "pencil in" originated in the 1940s and 1950s as shorthand for scheduling an event or appointment. At the time, schedules were often kept in paper planners or diaries, and events were added using a pencil, as it allowed for easy erasing and adjusting of plans. The idea behind "pencil in" is that the event is not yet considered set in stone, as it might be subject to change or cancellation. The use of a pencil, rather than a pen, conveys this idea of tentativeness and flexibility, as a penciled-in appointment can easily be erased and redrawn. As technology advanced and digital calendars became more common, the term "pencil in" persisted, becoming a widely used expression in both professional and personal contexts. It continues to be a versatile phrase, evoking a sense of adaptability and open-mindedness in scheduling or planning activities.
