Remember high school English and your teacher’s dreaded red ink? Several years ago, I was one of those English teachers. Given the amount of written communication in today’s workplace, the basic writing principles that I taught as a high school English teacher are still critical skills for adults. In my classroom, we would start the week with a worksheet of “Comon Writting Misteaks;” consider this list your flashback to sentence correction in high school!
- The first time you use an acronym, write the whole phrase and put the acronym in parentheses. After that, you can just use the acronym.
- Write the words for numbers ten and under. Use numerals for 11 and higher.
- Write in paragraphs that have a main idea and supporting sentences.
- Use proper spelling of words, not colloquial language. One I see all the time in emails is could of or would of. It’s what it sounds like when you speak it but it MUST be written as could have or would have.
- Don’t leave a preposition at the end of a sentence. It sounds a little awkward to say with which or for whom but those lost prepositions at the end of a sentence are like fingernails on a chalkboard for many readers!
- Use a semi-colon to separate two complete sentences; use a comma to separate items in a list or series of items.
- Be concise. This covers a wide variety of common writing errors! Longer sentences and paragraphs are not better; it is usually easier for a reader to mentally process shorter pieces of information. Avoid run-on sentences and full-page paragraphs.
- Be consistent in your use of italics, underlining, and bold text. At the same time, don’t over-format your text. It is very distracting to a reader to try to comprehend a sentence that contains different fonts or styles.
- Ensure you have parallel structure in bulleted lists or ideas in a series. For example, every item in a bulleted list might be capitalized and start with a present-tense verb.
- Proofread. Proofread. Proofread! As a professional writer, there is nothing more embarrassing than when someone points out a grammatical or spelling error in any of my writing, even if it’s a casual email to a friend. However, any writing done for business purposes must be proofread! It is hard to take seriously any business writing that contains blaring errors of spelling or grammar.
While this is only a very short list of best practices for writing, consider how you can use these guidelines whenever you are writing, whether it is for wallboard messages, corporate emails, communications with colleagues, or business bulletins.
