plough
A farming tool that cuts and turns soil for planting.
A plough (also spelled plow in American English) is a farming tool that breaks up and turns over soil to prepare it for planting crops. Picture a heavy blade or metal point being dragged through a field, cutting deep furrows as it moves. The plough slices into the earth, flips the soil over, and buries weeds and old plant material underneath.
For thousands of years, farmers walked behind ploughs pulled by oxen or horses, guiding the blade through their fields. This backbreaking work had to be done before every planting season. Modern tractors pull much larger ploughs that can prepare vast fields in hours instead of weeks, but the basic principle remains the same: break up compacted soil so seeds can take root and grow.
The invention of the plough was one of the most important moments in human history. It allowed people to farm larger areas more efficiently, which meant they could grow more food, support bigger populations, and build civilizations.
As a verb, plough can also mean to move forward with steady effort, pushing through difficulty. When you plough through a challenging book or plough ahead with a tough assignment despite setbacks, you're working persistently, like a plough cutting steadily across a field no matter how hard the ground.
