GRE pro tips:

The Latin prefix ob- means “going against,” “hindering,” or “reversing;” it appears in common words like obstruct and obstacle as well as in the more-challenging verb obviate. So it makes sense that obviating something can mean hindering it, or in other words, preventing or warding it off. As it’s usually used, obviating something specifically means reversing its necessity, or eliminating the need for it. For example, in medicine, a new treatment or therapy can obviate the need for surgery; likewise, keeping up with your studies all semester can obviate the need to cram for an exam.

Example sentences:

“These new therapeutic options can, in some instances, obviate the need for surgery.”

“For some parents, simply handing their kids a iPad obviates the need to parent.”
