Principal vs Principle - English Grammar - Teaching Tips


This video covers the difference between 'principal' and 'principle'. These two words often cause confusion for English learners due to their similar spelling. The word 'principal' can be used as a noun and as an adjective. As a noun, it refers to a person of authority, like a school principal, the head of a school. When used as an adjective, it means 'leading' or 'primary', like a principal cause or reason. The word 'principle', on the other hand, is only used as a noun and refers to a moral or standard, like the principle of free speech.

This future tense is slightly more complex in that there are three additional forms including the be going, present simple and present continuous. The latter two at first caused some confusion as it appears that this form can be used for either present and future purposes.
