Back to the basics: proper nouns vs common nouns
One of the main capitalization rules in English grammar is that all proper nouns are capitalized, no matter where they appear in a sentence. Proper nouns name specific people, places, things, or ideas. A person’s name is a proper noun, and so is the name of a country or company. That said, simply writing ‘country’ or ‘company’, does not require these words to take on a capital letter.
This is because they are common nouns: they refer to a general category or type of thing and do not point out a specific thing or entity. This chart shows the difference between both common and proper noun forms:
