WHEN SPELLING

— Spellers can ask for:

— Pronunciation

— Definition

— Use of the word in a sentence

— Language of origin

— Spellers can ask if a specific root is attached to the word, but they must define that root word and give language of origin. In other words, they can say, "is that from the French word 'pain' (pahn), meaning bread?"

— Spellers are asked to pronounce the word before spelling. Judges can correct them.

SPELLING "BEE"?

— Scripps itself admits the term "bee" is a language puzzle.

— The word "bee" has long been used for community gatherings like a "quilting bee."

— It dates back at least 240 years.

— Scholars once guessed bee was used because of the industrious nature of beehives.

— But more recently, researchers think its from an old English dialect in which "been" or "bean" means voluntary help for neighbors.
