What do a specialized linguist, an elephant's trunk and a system of inheritance have in common?

They're all really hard to spell.

Results are in from the second round of the Scripps annual spelling bee, and some of the precocious young participants stumbled over the tongue-twisting vocabulary that they were assigned (the above three words, by the way, are syntactician, proboscis and ultimogeniture).

Round three of the preliminaries wraps up this afternoon, after which the semifinalists will be announced. In the meantime, here's a list of the words that stumped spellers in round 2, with definitions.
