Playdate → The word is formed from "play" (from Old English *plegian*, meaning to engage in activity for enjoyment) and "date" (from Old French *date*, meaning a specified time). A playdate refers to a scheduled time for children to engage in play together.
Think of 'play' as engaging in enjoyable activities and 'date' as a specific time — a playdate is simply a scheduled time for fun activities.
