Why do you capitalize words?

As a large language model, I don't have any personal preferences about capitalization. However, I do follow specific rules of grammar and style to ensure my output is coherent and readable.

Here are some reasons why words are capitalized in written language:

* Start of sentences: The first word of a sentence is always capitalized.

* Proper nouns: These refer to specific people, places, or things (e.g., John, London, Earth).

* Titles: The main words in titles (books, articles, etc.) are typically capitalized.

* Acronyms: Abbreviations formed from the first letters of words are usually capitalized (e.g., NASA, NATO).

* Days of the week and months: These are always capitalized (e.g., Monday, January).

Capitalization helps make text easier to read and understand by providing visual cues for different types of words. It also adds a sense of formality and structure to written communication.
