A bull is an intact adult male of the species Bos taurus, which is more muscular and aggressive than the females of the same species. Bulls have long been an important symbol in many religions, including for sacrifices. They play a significant role in beef ranching, dairy farming, and a variety of sporting and cultural activities, including bullfighting and bull riding. Handling of bulls requires precautions due to their temperament. The female counterpart to a bull is a cow, while a male of the species that has been castrated is a steer, ox, or bullock. In North America, the term "bullock" refers to a young bull. A wild, young, unmarked bull is known as a micky in Australia.
In addition to its zoological meaning, "bull" has other meanings as well. According to Merriam-Webster, "bull" can refer to a person who buys securities or commodities in expectation of a price rise or who acts to effect such a rise. It can also refer to a grotesque blunder in language or empty boastful talk. "Bull" can also be used as an adjective to describe something that is suggestive of a bull or is large of its kind.
In terms of its appearance, a bull can usually be identified by its large size and horns.
