Proper noun which should start with a capital letter

[Kane]

Hello everyone

If I want to write any proper noun which should start with a capital letter, will the article before it also start with a capital letter? eg

The Principal or the Principal
The Taj Mahal or the Taj Mahal
Dear all or Dear All

Thank you very much

Kane

The articles before proper nouns don't start with a capital letter unless they are the first word in a sentence or in the title of a book, movie, etc.

So, normally in the middle of a sentence, you would write, "the Taj Mahal".

The word "principal" is not a proper noun, and it would not start with a capital letter unless it is used as a title right before a person's name. For example:

Fred is the principal of Tom Landy Middle School.
Attending the meeting was Principal Fred Patel.

Many a thank, Jamie

I am grateful for the prompt reply, but what about

Dear all and Dear All?

Thanks again
