Explanation

When you bypass something, you avoid it, go around it, or ignore it. You might wish you could just read the books assigned in your English class and bypass the papers and exams. You can bypass something physically, like when you bypass the busiest intersections in town during rush hour, driving on smaller streets instead. You can also bypass things figuratively: political candidates often bypass hard questions from reporters, and big businesses sometimes find ways to bypass some of the taxes they owe. As a noun, a bypass is either an alternative road or route; or a heart operation that allows blood flow when an artery is blocked.
