The English language certainly presents challenges to those who wish to attain fluency, but learners can look forward to unexpected delights along the way. Supervocalics are delightful!
supervocalic (adj) - a word, name, or phrase in which the five vowels–AEIOU–appear exactly once each in any order
BREAKDOWN: SUPER- (over) + VOC- (speak) + -AL (pertaining to) + -IC (like)
—a supervocalic is any word, name, or phrase that follows the supervocalic vowel structure
FUN FACT 1: The letter Y may sometimes be considered a vowel, but not for purposes of supervocalics.
FUN FACT 2: Supervocalic words are surprisingly common. Here’s a short list, at least one of which has appeared here on Roots2Words: ambidextrous, cafetorium, delusional, euphoria, facetious, gregarious, hallucinogen, intravenous, menstruation, pandemonium, precaution, sequoia.
FUN FACT 3: While we cover American English here, British English presents abundant additional supervocalics, including behaviour and favourite.
FUN FACT 4: The word supervocalic is itself supervocalic.
