Farming is the act or process of working the ground, planting seeds, and growing edible plants. You can also describe raising animals for milk or meat as farming.
Farming is a great way to describe the lifestyle and work of people whose jobs are in the agriculture industry. People often have a romantic idea of what farming is like — roosters crowing, farmers driving tractors and milking goats — although farming can be very hard work, dependent on food prices and weather. The noun farm originally meant "a lease on farm land," and it comes from the Medieval Latin firma, "fixed payment."
