The close-mid front rounded vowel, or high-mid front rounded vowel, is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is 〈ø〉, a lowercase letter o with a diagonal stroke through it, derived from the Danish, Norwegian and Faroese alphabets which use the letter to represent this sound. The symbol is commonly referred to as "o, slash" in English.
The IPA prefers terms "close" and "open" for vowels, and the name of the article follows this. However, a large number of linguists,[who?] perhaps a majority, prefer the terms "high" and "low".
