What's the main difference between a grass, a weed and a lawn? Are they all interchangeable?

Native speaker’s answer

Rebecca

"Grass" refers to the plant. "Weed" refers to unwanted plants that invade or harm other plants. "Lawn" refers to the area, not the plant. They are not interchangeable. Each word has its specific meaning. Ex: She can distinguish grass from weeds so she can remove weeds from her lawn without harming the grass. Ex: Why does her lawn look healthy and pleasing to the eyes? It's because she knows how to deal with weeds and take care of the grass.
