On this page, “the five vowels” refers to a, e, i, o, u, and “the six vowels” refers to those letters plus the letter y.


Words consisting entirely of vowels include A, AA (a type of lava), AI (the three-toed sloth in Chambers and a Biblical place name and a Russian river), AIEEE (an interjection in the OED), AIOUEA (a genus of the laurel family (Lauracea) [Charles Turner], EUOI (cry of Bacchic frenzy), EUOUAE, I, IAO, IO, (an interjection in Chambers; one of the moons of Jupiter), IOUEA (a genus of Cretaceous fossil sponges), O, OII, OO ("wool" in Scottish), UOIAUAI (a language in Par´ State, Brazil) [Dmitri Borgmann, in Charles Bombaugh's Oddities and Curiosities of Words and Literature).

The scientific name of the roseate spoonbill is AJAIA AJAIA (or AJAIA AJAJA); however, the J's would have been I's in the original Latin spelling, so that the words would consist entirely of vowels also.

Some all-vowel Hawaiian names for birds which are used in English are AO - Puffinus puffinus (Manx shearwater), UAU - Pterodroma phaeopygia (Dark-rumped Shearwater), OEOE - Oceanodroma castro (Harcourt's Storm-petrel), IO - Buteo solitarius (Hawaiian Hawk), OOAA - Moho bracatus, OU - Psittirostra psittacea.

Allowing proper nouns, some words consisting only of vowels include AIEA (a city in Hawaii), EIAO (one of the Marquesas Islands), EA (a town in the Basque section of Spain), AEAEA (the legendary home of Circe in the Tyrrhenian Sea), AAUAUA (a river in Brasil), II (a place in Finland 40 km north of Oulu), and OUEOI (an ancient Tuscan city in Etruria). IO is the only name on any hurricane name list which consists entirely of vowels. It is on the Central Pacific hurricane name list [Brett Brunner, Juozas Rimas, Stuart Kidd, Pertti Malo]. Dmitri Borgmann gives OEAEI (the name of the wife of Ra-amen, the spondist of Pthah) [An Archaic Dictionary, From the Egyptian, Assyrian, and Etruscan Monuments and Papyri, by William R. Cooper, London, 1876]. OUADI EL AOUAOUIYE is a location in Syria, AOUEOUA in Mauritania, and AOUEOUE in Togo [Rex Gooch].

Allowing Y as a vowel, some words consisting only of vowels include AYE, AYU, EYE, IYO, EYEY, and YAYA (although I am not sure which of these Y's are vowels!).


Allowing proper nouns, CAUAIAUAIA in Angola has nine vowels in a row, as does URU-EU-UAU-UAU (a language of Brazil with about 100 speakers in 1995; also spelled URUEWAWAU or ERU-EU-WAU-WAU), ignoring hyphens and OUADI EL AOUAOUIYE, in Syria [Susan Thorpe, Rex Gooch].

[The Book of Names, J. N. Hook.] Other place names with 7 vowels in a row include AOUEOUA, (Mauritania), AOUEOUE, Togo, BOUAAOUAM (Algeria), TIOUOOUORT (Mali), and ES ZOUAOUIINE and TAZOUOUOUARHT (Morocco) [Susan Thorpe, Rex Gooch].

Words with five consecutive vowels include QUEUEING, the interjection AIEEE, which is in the OED, and COOEEING. (COOEE or COOEY, a peculiar cry of the Australian aborigine, is in W1, W2, and W3. The word is also a verb and both W1 and W2 show the forms COOEEING and COOEEYING.) The OED2 has COUUIENALES, which is a variant of quienals, which comes from quiennal, meaning "dispensation or indulgence for five years."

The first 20 or so poems use only the letter A, the next 20 use only E, and so on through I, O, and U. The book claims that eunoia means “beautiful thinking” and that it is shortest word using all five vowels. However, the word does not appear in English language dictionaries.

Craig Rowland reports that in Quebec, there is a region known as the Outaouais, which, if in adjectival form, becomes lowercase, hence outaouais.

Every place name in Estonia ends with a vowel, except for the capital Tallinn. The reason for ending locations with a vowel is because all place names (except for Tallinn) are in the genitive case, which always ends in a vowel. Tallinn is in the nominative case (which can end in any letter). The name Tallinn(a) is Estonian. It is usually thought to be derived from Taani-linn(a), (meaning 'Danish-town) (Latin: Castrum Danorum), after the Danes built the castle in place of the Estonian stronghold at Lindanisse. (In neighboring Finland, the Estonian capital is called 'Tallinna') Tallinna and Tallinn were both used until 1933, when it was changed to just Tallinn. It's not entirely clear why it was officially changed to that. The reason may have been to make the name of the Estonian capital special - to be the only place name in that country which ends with a consonant. (or really, the only place name in nominative case).
