Tips for Writing Professionally
Introduction
In freelancing, business, schooling, and any professional work, being able to effectively communicate through writing is very important, if not essential. Especially in situations like applications, interviews, cover letters, resumes, and other forms of professional communication, your writing style and quality say a lot about you before your potential employer even really meets you. Many things can make writing come across as unprofessional, and in this article, we'll talk about how to avoid some of them.
Pitfalls
Writing that conveys unprofessionalism can have any number of things wrong with it, and the following elements are often a source of mistakes.
Punctuation: When writing, punctuation is very important, and it serves many functions. It can indicate tone, break up a sentence so it's easier to read, and guide the reader's "head voice." When proofreading, make sure all your punctuation is correct -- barring generational habits like the Oxford comma or putting two spaces after a period, there is a right and wrong way to punctuate writing.
Avoid long, rambling sentences with no punctuation. Varying your sentence length is good, and it gives a better flow to your writing, but making sentences too long can make them confusing and hard to follow.
Capitalization: Certain words are capitalized, and certain ones are not. In creative writing, there's a lot more leeway with this, since capitalizing words (or not) can be a stylistic choice; but in professional writing, it's best to avoid this, and stick to the general rules.
Always capitalize the first word after a period, at the beginning of a new paragraph, and at the beginning of a new bullet point or list item.
Capitalize names, including the names of people, places, organizations, brands or branded products, etc.
Remember which words are sometimes capitalized. English as a language likes to break its own rules, and sometimes, words are capitalized depending on their meaning. Below are some examples.
If you're talking about the planet that humans live on, "Earth" is capitalized, because it's the name of a place. If you're talking about the ground or the dirt (e.g. "the farmer salted the earth") then it isn't.
As a name, "Smith" is capitalized (e.g. "John Smith") but as a profession (e.g. "the smith bought metal") it isn't.
Spelling: If you're writing on a computer in any kind of word processor, spelling mistakes are trivially easy to avoid. Even many chat room-style processors have basic spellcheck, and major word processors like Google Docs or Word have advanced spelling and grammar-checking algorithms; some will even notify you of incorrect punctuation. Beyond that, most major web browsers (Chrome, Edge, Firefox, Safari, etc) have extensions like Grammarly that will check all of your text everywhere, even if there's no built-in spellcheck where you're typing. At this point, spelling errors have become almost inexcusable in professional writing because of how easy they are to fix.
Spellcheck can be wrong, but most of the time it isn't. If something doesn't sound or look quite right, it's always worth it to check using Google or another spellchecker.
Slang: Slang is a catch-all term used for colloquial, informal words, terms, or phrases. Think things like "lit," "salty," "shook," and "low/high key." Slang terms should generally be avoided in professional writing, if not because they come across as informal then because the people reading whatever you're writing might not understand what you mean. Slang is different from jargon, which is talked about in more detail below.
Audience-Appropriate Language
Grammar, spelling, and punctuation aren't all there is to professional-sounding writing. In fact, I would argue that one of the most integral things to sounding professional is using the right language at the right time.
What is audience-appropriate language?
Using "audience-appropriate language" means that, in your writing, you use phrases, jargon, key terms, and other words that are applicable to the audience you're writing to. You wouldn't use the same words for a presentation to your boss as you would for writing an email to a colleague; you wouldn't use the same words in a biology lab report as you would in a physics lab report; you wouldn't use the same words to critique music as you do to critique visual art. Similarly, the language you use in creative writing is not the same as the language you should use in professional writing.
