A "Bachelor" typically refers to an individual who has completed an undergraduate degree, often in fields such as arts, science, or business. This degree is usually awarded by a college or university after a student has completed a specific number of courses and credits, generally taking about four years of full-time study.
In a different context, the term "bachelor" can also describe an unmarried man. This usage often implies that the individual is not in a committed relationship or has not yet married. The term is commonly associated with social events, such as bachelor parties, which celebrate the transition from single life to marriage.
