I took Tastidian's post and took out all of the ones 11 letters or more, and most of the ones that are irrelevant, and the repeats.
[spoiler=second words]academic, augur, bookworm, brain, critic, disciple, doctor, egghead, learner, professor, sage, savant, scientist, student, tool, pundit, authority, academic, teacher, historian, biographer, linguist, geographer, classicist, grammarian.[/spoiler]
And then there's a list of synonyms for "smart."
[spoiler=first words]acute, adept, agile, alert, apt, astute, bold, brainy, bright, brisk, canny, clever, crafty, fresh, genius, good, keen, knowing, nervy, nimble, pert, quick, ready, sassy, sharp, shrewd, skull, slick, whiz, wise[/spoiler]
As with the second words, I took out all the words over length 7 (7 because the shortest of words in the top words is 4 long). Then I went back to the second words, and shortened the max length to 8, as the shortest in the first words is 3.
[spoiler=second words - revised]augur, brain, critic, doctor, egghead, learner, savant, student, teacher, tool, pundit, sage.[/spoiler]
And finally, I used a Flash program to put them all together.

Happy testing!
Or maybe I'll test them all and get back to you... but if you (whomever reads this) would like to find it first, then you'd probably get it done faster.
