sagacious

"The sagacious reader will not from this simile imagine these poor people had any apprehension of the design with which Mrs. Wilkins was now coming towards them; but as the great beauty of the simile may possibly sleep these hundred years, till some future commentator shall take this work in hand, I think proper to lend the reader a little assistance in this place."
- Henry Fielding, 'The History of Tom Jones'.

Nice wordie but your mishap was not sagacious but innocuous. Could you have spelled that? :)

Here's a fun little anecdote I found on MyFavoriteWord.com, by Sheila Confer:

"I was an outstanding speller in my youth. In seventh grade I won the school wide spelling test and got to go all the way to Pittsburgh, PA for a regional final. Out of 700 (probably more like 30) children, I survived until the final three. My word? Sagacious: Having or showing keen discernment, sound judgment, and farsightedness. I spelled it "s-E-g-a-c-i-o-u-s."

It is my favorite word for two reasons. One, I will never forget how to spell it, and two, the winner of the contest had to spell tulle: A fine, often starched net of silk, rayon, or nylon, used especially for veils, tutus, or gowns. I would have surely spelled it t-o-o-l and been embarrassed for life. It was therefore very sagacious of me to misspell sagacious...right?"
