The words “principal” and “principle” sound identical but have completely different meanings and spellings. Such words are known as homophones. Their existence in the language of English leads to a lot of confusion. Both these words carry distinct meanings.
Hence, it is important to understand their definitions and usages to use them appropriately in right context.
Definition of the Principal
The word “Principal” can be used as both a noun and an adjective.

Tips to Remember the Difference
Although “principal” and “principle” sound the same, different tricks can be used to remember their difference:
