Example of a confusing word: principal (main or head)

▪The principal of fairness guides us.
▪The main element of fairness guides us.
"Principle" is a noun meaning "a fundamental truth or proposition serving as the foundation for belief or action." It is correctly used in the sentence "The principle of fairness guides us," indicating a guiding rule or belief. "Principal," however, can mean "main" as an adjective or refer to a person with the highest authority in an organization, like a school principal. Using "The principal of fairness" is incorrect here because it suggests a person or the main aspect, which doesn't fit the context of a guiding rule. Therefore, "principle" is the correct choice.
