Explanation

Vexatious describes something that drives you crazy. The kid you're babysitting refusing to go to bed might be vexatious, for example. Something vexatious, pronounced "veks-AY-shus," is irritating or annoying, like an itch in the middle of your back that you can't reach, or a task that you need to do for work.
