100 Capitalization (English)
Home >> Grammar Style Guide >> Capitalization
As long as the first letter of a sentence is capitalized, there are no other steadfast rules for what can and cannot be capitalized in that sentence. However, aside from starting a sentence, capitalization is used to set off or draw attention to a specific word or phrase, so as a general rule, capitalization should be limited to only what is essentially needed to be capitalized, such as proper nouns.
A proper noun is any person, place, or object that has a unique name to identify it, such as the city of New York or New York City.
When introducing a proper noun, the article can be capitalized if it is part of the proper noun, such as the case of the title of a book; otherwise, it is only capitalized if at the start of the sentence.
When providing a byline after a headline, the word by is not capitalized.
For example, my_file_name.doc would be written as follows in camel case: MyFileName.doc.
In that example, MyFileName is using camel case capitalization.

Camel case capitalization became popular among computer programmers to save time from having to place underscores between words in file names.
