Want that big promotion at work? Simply say “yeah” in meetings and you could be well on your way.

A study by MIT Sloan School of Management looks at different words used in business meetings, and which (if any) might increase an employer’s likelihood of agreeing with an employee’s suggestions.

It turns out the word “yeah” is key. It came out far above words like “drive,” “results” and “accomplish.”

Other words that got colleagues to agree on proposals include: “menu,” “start,” “meeting,” “give,” and “discuss.” Meanwhile, “recognition,” “speech,” “fair,” “flat,” “middle,” and “bottom” did not.

So next time you want to get ahead at work, start by getting your ideas heard at the next meeting.
