Jeffy was always up for a challenge, so he decided to recite the longest word in the English language just for fun. He took a deep breath and began, Pneumonoultramicroscopicsilicovolcanoconiosis… Unfortunately, he tripped over the pronunciation and ended up saying, Pneumonoultramicroscopicsilicovolcanoconiosis coni… Oops! Looks like Jeffy needs a little more practice before he can master this tongue twister.
