A principal is a person in a position of authority and leadership within an organization, most commonly associated with educational institutions such as schools. In the context of a school, the principal is responsible for overseeing daily operations, implementing policies, managing staff and students, and ensuring the institution’s educational objectives are met. The role often includes administrative duties, curriculum oversight, and acting as a liaison between staff, students, parents, and the community.

The term "principal" can also refer to the primary or most important element in other fields, such as business or finance. For example, in finance, the principal is the original sum of money invested or loaned, separate from interest or earnings. In a business setting, the principal might also refer to an individual who holds a key decision-making role, such as a principal partner or principal executive.

The origin of the word "principal" is from Latin "principalis," meaning "chief" or "main." In educational settings, the role's responsibilities can vary depending on the size and type of the institution, but the core focus remains on leadership and management.

In legal and organizational terms, a principal might also be a person who authorizes an agent to act on their behalf. Overall, the term encapsulates the idea of leadership, primary importance, or fundamental responsibility across various contexts.
