The letter is not to be confused with the slashed zero, slashed (Ø ø), the Greek phi , , the Cyrillic letter ef Ef Ef, the Tifinagh letter yah , the IPA symbol Voiceless bilabial fricative or the mathematical symbol Mathematical operators and symbols in Unicode, despite their similar shapes.

Usage

It was the 20th letter of the Metelko alphabet, used to represent the sound [ɔ].[1]

In Unifon, it is used to represent the sound [o]. It is included in the variants for English (the 23rd letter of the alphabet), Hupa (No. 20), Karuk (No. 16), Tolowa (No. 20), and Yurok (No. 18), and in variants of the Shaw-Malone Forty-Phoneme Alphabet (No. 24) and the Indian Unifon Single-Sound Alphabet (No. 26). As with the other letters, only the uppercase form is used, for the sound .[2][3][4][5]

Isaac Pitman used the vertically barred in a trial version of the phonotypic alphabet in 1843.[6] The letter has also appeared in various linguistic and phonetic studies as a way to distinguish vowel qualities, and in typographic experiments where visually modified Latin letters are used for additional sounds.

Computer representation

The vertically barred has not been added to a standard Unicode encoding. Existing characters may appear similar but are only glyph variants.

The character looks similar to the long , of the Deseret alphabet or the Tifinagh letter yah .[7]

History

The vertically barred is derived from the Latin letter O and is formed by adding a vertical stroke through the letter. The vertically barred form follows a common practice in Latin-based writing systems, where existing letters are modified to represent additional sounds. By keeping the basic shape of the letter O and adding a vertical bar, the vertically barred O remains visually recognizable while signaling a distinct sound value.[8]
