Capitalization rules

Capitalization
Capitalization of words can often be tricky and confusing.  A good rule of thumb is that words are capitalized if they are unique persons, places, or things, or if, in a title, theyare important.  Of course, all sentences begin with a capital letter, as well.
Proper nouns and proper adjectives are always capitalized.  They fall most often into the following categories: Category | Example | Notes |
