What is rhopalic text? Well, here's a nice example of a piece:-
"I do not know where family doctors acquired illegibly perplexing handwriting; nevertheless, extraordinary pharmaceutical intellectuality, counterbalancing indecipherability, transcendentalises intercommunications’ incomprehensibleness."
Rhopalic describes text in which each word contains one more letter or syllable than the one preceding it. This text starts with 1 letter, then 2, then 3 and so on.... Clever stuff.
