Principal—the main thing. Often used of the owners of a company, or the chief administrator of a school, but it can apply to inanimate things, too. The principal reason we took a break was that we were tired.
Principle—a rule. Note that “rule” and “principle” both end in “-le.” He tells the truth as a matter of principle.
Rule, ruler, hnnnnngh! as a friend of mine would say.
