beginning
The time or place where something first starts.
A beginning is the point where something starts. Every story has a beginning where you meet the characters and learn what's happening. Every friendship has a beginning, maybe the first day you sat together at lunch or discovered you both loved the same game. The beginning of a school year feels different from the middle or end: everything is fresh, you have new supplies, and the year's possibilities stretch ahead.
Beginnings can feel exciting or nerve-wracking, sometimes both at once. The beginning of a race gets your heart pounding. The beginning of learning piano means simple songs and patient practice. At the beginning of building something, you might have only raw materials and a plan.
Some beginnings are obvious, like when a teacher says “Let's begin” or a movie starts with opening credits. Other beginnings are quieter: the first time you got curious about astronomy, the moment you decided to learn chess, or the day you first tried drawing seriously.
People often talk about making a new beginning, which means starting fresh after something didn't work out. When you understand something “from beginning to end,” you know the whole thing completely. The beginning matters because it sets everything else in motion, like the first domino in a long chain.
