It’s the principal principle

Principle or principal?

They sound the same and look similar, but their meanings are different, so how do you know which one to use?

A principle (noun) describes a fundamental truth, law or belief. It can also stand for a personal code of conduct, as in ‘a man of principle’. A principle can also describe a scientific, mechanical or other law or rule, such as the principle of nuclear fission.

Principal (adjective) describes something that is first in rank or importance. The principal members of the cast of a play are the main or leading actors. A principal (noun) describes the head of an institution, such as a school or college.

The difference between the ple and the pal ending is an important one.
