Definition: Out of money, penniless.
Impecunious comes to us from the Latin word pecunia, meaning money. Pecunia became pecuniosus meaning rich, moneyed, or wealthy. It entered English around 1590 as pecunious and was then combined with the prefix im- to convey a negation or the absence of money. Pecunious is still used today but, just as impecunious, it is extremely rare.
Why this word?
Let’s face it, we’re not all rich. Odds are you lie in the 99% and not the 1%. So who couldn’t use a word other than “broke” to demonstrate that you are currently a bit short on funds? One could argue that the use of such a word would demonstrate that while you are lacking in economic wealth, you are rich in intellectual resources.
