(pronounced OH-neh-rehs or AH-neh-rehs)

Said with the correct tone of voice, this word sounds a little like what it means: troublesome, imposing, daunting, or representing a burden.

Example: During the four-floor office renovation project, someone from the design firm was going to have to take on the onerous job of being the messenger-cum-mediator between the company’s feuding department heads and their facilities manager.
