Looking for a better word than “principal”? Be careful: principal has several distinct meanings, so the right synonym depends on how it is used. As an adjective, it can mean main, primary, chief, or most important; as a noun, it can refer to a school leader, the original amount of money borrowed or invested, or a person who authorizes an agent to act on their behalf.
For example, the principal reason can be the main reason, a school principal can be called a school administrator, and the principal on a loan is the original amount borrowed. In an agency relationship, a principal is the person on whose behalf an agent acts, although the most suitable alternative depends on the specific context.
