Yes — English does include words composed entirely of vowels. The simplest examples are single-letter words like a and I, which function as independent words in sentences.
More unusually, the medieval musical term euouae (a mnemonic for a sequence of tones) is an English entry found in some dictionaries and is notable for containing only vowels. Such words are rare and often come from proper nouns, interjections, abbreviations, or borrowings.

In everyday vocabulary you’ll mostly encounter vowel-only words as short exclamations or articles; longer vowel-only strings are typically specialized or archaic. If you’re looking for playable examples in word games, check whether your dictionary allows forms like euouae or vowel-only interjections.

If you want a quick list: a, I, and the rare euouae are the clearest examples. For more lexical oddities, explore word-lists or specialty dictionaries that document archaic and musical terms.
