FAQ
What is the difference between an i with a circumflex accent and an i with a diaeresis?
A circumflex accented i (^) indicates that the i is pronounced like an è or an é. It is used to mark the absence of a letter that has disappeared during the evolution of the language. For example, in the word île (island), the circumflex accented i indicates that there was once an s (isla in Latin). A diaeresis i (¨) indicates that the i is pronounced like an i. It is used to separate the i from another vowel sound. For example, in the word naïf (naive), the diaeresis i indicates that the i is pronounced after the a and not with it.

What is the origin of the diaeresis on the ï?
The diaeresis (or umlaut) is a diacritical mark that comes from Ancient Greek. The word diaeresis means “hole” in Greek and refers to the two dots placed above a vowel to indicate that it is pronounced separately from another vowel. The diaeresis was introduced into the Latin alphabet in the Middle Ages to transcribe Greek or Latin words that contained distinct vowel sounds. For example, the word zoology comes from the Greek words zôion (animal) and logos (discourse) and was originally written zoölogie with a diaeresis over the o to indicate that it was pronounced after the z and not with it.
What is the spelling rule for the diaeresis mark on the letter ï?
The spelling rule for the diaeresis (ï) is to use it when there are two consecutive vowels, the first being an e or an a, and the second an i. The diaeresis then serves to indicate that the i is pronounced separately from the first vowel and not with it. For example, in the word *haïr* (to hate), the diaeresis on the i indicates that it is pronounced after the a and not with it. There are some exceptions to this rule, such as the words *oignon* (onion) and *paon* (peacock), which are written without the diaeresis even though they meet the condition.
