Etymology

Origin of imponderable

From the Medieval Latin word imponderābilis, dating back to 1785–95. See im- 2, ponderable

Explanation

Imponderable describes a situation that isn't able to be completely explained. "What is the meaning of life?" is one of those imponderable questions that defies humans' ability for understanding If something is ponderable, it is capable of being assessed or weighed; stick im- in front and you get the opposite effect. Use imponderable to describe something that is elusive and vague, perhaps even evasive. When your question doesn't have a definitive answer, you are in imponderable territory: "Life has many imponderable questions, such as why you park in a driveway and drive on parkway."
