We were going about our regular morning work, capitalizing those proper nouns and adding punctuation to one big long strung-together set of words posing as a coherent paragraph. "My dad taught me about that!" exclaimed Marcus. "It's a runaway sentence!"
Epilogue: After my initial delight over Marcus' new term, a quick online search revealed that the phrase "runaway sentence" may not be an authentic Marcus Wiley original. Darn! It's always so great when kids create a brand new phrase that's really far more apt than the original. One such term I particularly enjoyed a few years ago was Jamal's name for that tape-dispensing thingy that sits next to the stapler. A tape-ler.
Have you heard of a runaway sentence before? Apparently it's much more out of control than a mere run-on.
