In rhetoric, a rhopalic is a sentence in which each successive word is one syllable or one letter longer than the previous one. It is derived from the Greek word rhopalikos, meaning “a tapered cudgel or club.” Here are some examples of rhopalics:
A lucid manager organize unregenerate, uncooperative antiphrohibitionists’ incomprehensibility.

I am not very happy acting pleased whenever prominent scientists overmagnify intellectual enlightenment, stoutheartedly outvociferating ultrareactionary retrogressionists, characteristically unsupernaturalizing transubstantiatively philosophicoreligious incomprehensiblenesses anthropomorphologically. Pathologicopsychological!
I do not know where family doctors acquired illegibly perplexing handwriting; nevertheless, extraordinary pharmaceutical intellectuality, counterbalancing indecipherability, transcendentalizes intercommunications’ incomprehensibleness.
I am the only dummy player, perhaps, planning maneuvers calculated brilliantly, nevertheless outstandingly pachydermatous, notwithstanding unconstitutional unprofessionalism.
