Business Insider consulted two job coaches, Dana Leavy-Detrick of Brooklyn Resume Studio and Jared Redick of Résumé Studio in San Francisco, about words that are often spelled wrong on resumes.

Here are a few words the coaches identified — along with other ones that might be making you look dumb at work.

People apparently get these words wrong on their resumes

Do you?

‘Implement’

Leavy-Detrick told Business Insider that its common for her clients to use the letter “i” and “e” wrong, but that it’s “implement,” instead of “impliment.”

‘Ensure’ vs. ‘insure’

Leavy-Detrick told Business Insider that people confuse these. As Business Insider notes, to “ensure” something is to make sure that something is the case. To “insure” is to provide or obtain insurance.

‘Definitely’

A surprising number spell this as “definately.”

Be sure not to misspell any of these words, either

Ladders has also compiled our own list of words that might be making you look bad at work — the Oxford English Dictionary says these are commonly misspelled words, based on the Oxford English Corpus.

You won’t want to get these ones wrong on your resume.

“Knowledge”

Oxford says to “remember the d,” because this is often spelled like “knowlege.”

“Colleague”

Oxford’s memory trick is “-ea– in the middle,” and says that this word is often spelled like “collegue.”

“Business”

Oxford recommends keeping in mind that this word “begins with busi-,“ because it’s often spelled like “buisness.”

“Liaise,” “Liaison”

Here was Oxford’s suggestion: “remember the second i: liais-” — the dictionary says that “liase, liason” are how these words are commonly misspelled.

Here’s how to avoid spelling traps on resumes

It’s easy to fall into these, but you don’t have to.

Go through it, word for word

Career expert Alison Doyle writes about how to do this in The Balance.

“Spell check then proofread by placing a finger on each word and then have your document reviewed by a career coach or a friend or family member. It’s hard to catch your own mistakes, so having someone else read your resume for you will help. Reading it out loud is another option for catching mistakes,” she writes.

Get an expert on your side

Sarah Landrum, a freelance writer, Digital Marketing Specialist and founder of Punched Clocks, writes about this in Entrepreneur.

“While you may not need professional editing services each and every time you send in a resume, hiring an editor to comb through your resume before you hit the job market hard is a good idea. Because it is an editor’s job to look for mistakes and make suggestions, they can ensure you’re sending in the best version of your resume possible,” she writes.

She adds: “In addition to your resume, they can also proof your application, cover letter, portfolio and other crucial correspondences. Consider hiring an editor with experience editing resumes. The writing you use in a resume is typically much more direct than someone would use in sales copy or in a novel. Using an editor who specializes in editing job search documents can give you a leg up on the competition.”
