Usage of Principal
The word principal can be used as both a noun and an adjective.
As a noun, principal most commonly refers to a person who holds a high position of authority. This[5] is often the head of a school or educational institution. It can also denote a leading person in other contexts, such as the principal performer in an orchestra or a key figure in a business. In finance,[5] principal refers to the original sum of money invested or lent, separate from interest.
As an adjective, principal means "main" or "most important." It is[3][1] used to signify the primary or leading element among others. For example, one might refer to the "principal ingredient" in a recipe or the "principal cause" of an event.
[1]= Usage of Principle =
Principle is exclusively a noun and typically refers to a fundamental truth, law, or doctrine. It can describe a moral rule or a standard of good behavior. For instance, a person might refuse to do something "on principle" or be described as a "person of principle."
The term also applies to established scientific laws or the basic tenets of a system. Examples[1] include the "principles of physics" or the "principles of democracy." The phrase "in principle" is used to convey agreement with an idea in theory, though perhaps not in practice.
