Pasture is a vast expanse of land used for grazing livestock such as cows, sheep, and horses. The word has several synonyms that describe the same concept. These synonyms include prairie, meadow, range, grazing land, grassland, paddock, and field. All of these words have a common thread of indicating an area of land that is primarily used for animal grazing. Some synonyms have a slightly different connotation, such as "meadow" which often refers to a smaller, more manicured area of pasture. Regardless of the specific synonym used, all point to an open area of land utilized for feeding livestock and maintaining their health.
