A way to show important events in the order they happened, often used to illustrate history or plan activities.
The teacher created a timeline of the major events in World War II for the students to study.
Timeline → It is formed from "time" (from Old English "tīma", meaning a period or duration) and "line" (from Latin "linea", meaning a line or thread). The word "timeline" refers to a linear representation of time, showing events in chronological order.
Think of a 'line' that represents a 'period' of 'time' — that's what a timeline does, it shows events in a straight line over time.
