If you’ve ever written a cover letter or resume that claims you have “excelent attention to detail,” but you misspelled “excellent,” you can understand the importance of checking your grammar before hitting send on an application. Good grammar helps you present yourself as a smart, capable candidate who can communicate effectively—which is highly attractive to hiring managers.

So if you want to avoid an embarrassing—and potentially costly—grammar blunder, it’s important to conduct a grammar check. Below are four grammar mistakes that continually trip up job seekers and workers alike. Before you send your next email, format your resume or draft a cover letter, be sure to check for these common errors.
