Here's why:
* Standard Writing Conventions: English writing follows specific capitalization rules. Capitalizing the first letter of a sentence, proper nouns (names of people, places, organizations), and certain titles is the norm. Capitalizing every letter makes your writing appear unprofessional and difficult to read.
* Clarity and Readability: Capitalization helps readers visually distinguish between sentences and identify proper nouns. All-caps text can be jarring and make it harder to understand the flow of your writing.
* Purpose: Capitalization serves a purpose in conveying meaning and structure. It's not simply a matter of aesthetics.
Exception:
* There are some specific cases where all-caps might be used for emphasis, like shouting or specific types of typography. However, these instances are rare and should be used judiciously in formal writing.
In summary:
* Stick to standard capitalization rules for a professional and readable essay.
* Capitalize only the first letter of a sentence, proper nouns, and specific titles.
