Definition:
principal is a noun that refers to a person who is the head of something, such as the head of a school, company, or organization, or the primary or most important person or thing associated with it. Its role and function in the English language is to describe this person or thing, typically in a leadership position and, in some cases, to mean a principal sum of money, usually in a loan or amount of debt.
Examples:
She is the school's principal.
He is the principal of the company.
This is the principal sum of money that has been borrowed.
Tips:
tips associated with its usage include making sure to pay attention to the context in which the word is being used, whether to refer to a person or a sum of money.
Definition:
when 'principal' is used as an adjective, it primarily describes something that is of the greatest importance, primary, or holds the highest rank. It can refer to a main figure, element, or factor in a particular context.
Examples:
The principal reason for our success is our dedicated team.
The principal amount of the loan does not include interest.
She played the principal role in the play.
Tips:
One of the most common mistakes in English is confusing 'principal' with 'principle.' Remember, 'principal' can be an adjective (as described above) or a noun referring to a person who has a leading position (especially in a school). On the other hand, 'principle' is always a noun and refers to a fundamental truth, law, doctrine, or motivating force. When trying to remember the difference, a helpful mnemonic is 'The school principal is your pal, and a principle is a rule.'
