palaeoaeolian
n.— «Found a word my discussion leader professor wants to get used in scientific journals someday: palaeoaeolian. As in “palaeoaeolian rock”—a rock that was shaped by winds over the centuries. If it gets coined, it will become the word with the most vowels in a row.» —“studying” by neuroticsquirrl Neurosis (San Antonio, Texas) Dec. 16, 2004. (source: Double-Tongued Dictionary)
