The spelling of the name "Miley" is fairly straightforward. It is composed of two syllables: "mi" and "ley." The first syllable, "mi," is pronounced like "my," with a long "i" vowel sound. The second syllable, "ley," is pronounced with a long "a" vowel sound, like "lay." Therefore, the word is pronounced like "MY-lee." It is important to note that when using the International Phonetic Alphabet (IPA), "Miley" would be transcribed as /ˈmaɪ.li/, with the stress on the first syllable.
The word "Miley" is derived from the given name Miley, which is a variant of the name Miley/Mylie/Mileyey, which can be found as both a surname and a given name. Its origin is uncertain, but it is believed to have Gaelic or Irish roots.
