I with Diaeresis.svg

Ï, lowercase ï, is a symbol used in various languages written with the Latin alphabet; it can be read as the letter I with diaeresis or I-umlaut.

In Afrikaans, Catalan, Dutch, French, Galician, Welsh, Southern Sami, and occasionally English, ï is used when i follows another vowel and indicates hiatus (diaeresis) in the pronunciation of such a word—that is, it indicates that the two vowels are pronounced in separate syllables, rather than together as a diphthong or digraph. For example, French maïs (IPA: [ma.is], maize); without the diaeresis, the i is part of the digraph ai: mais (IPA: [mɛ], but). The letter is also in Dutch Oekraïne (IPA: [ukrɑːˈinə], Ukraine), and English naïve (/nɑːˈv/ or /nˈv/).

In scholarly writing on Turkish, ï is sometimes used to write the close back unrounded vowel /ɯ/, which in standard modern Turkish orthography is written as the dotless i ı.

In the transcription of the languages of the Amazon, ï is used to represent the high central vowel [ɨ].
