, used in the
modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is
''o'' (pronounced ), plural
''oes''.
History
Its graphic form has remained fairly constant from
Phoenician times until today. The name of the Phoenician letter was
''
ʿeyn'', meaning "eye", and indeed its shape originates simply as a drawing of a human eye (possibly inspired by the corresponding
Egyptian hieroglyph
Egyptian hieroglyphs (, ) were the formal writing system used in Ancient Egypt, used for writing the Egyptian language. Hieroglyphs combined logographic, syllabic and alphabetic elements, with some 1,000 distinct characters.There were about 1,00 ...
, cf.
Proto-Sinaitic script).
Its original sound value was that of a consonant, probably , the sound represented by the cognate
Arabic letter ع ''ʿayn''.
The use of this Phoenician letter for a vowel sound is due to the early
Greek alphabets, which adopted the letter as
O "omicron" to represent the vowel . The letter was adopted with this value in the
Old Italic alphabets
The Old Italic scripts are a family of similar ancient writing systems used in the Italy, Italian Peninsula between about 700 and 100 BC, for various languages spoken in that time and place. The most notable member is the Etruscan alphabet, ...

. In Greek, a variation of the form later came to distinguish this long sound (
Omega, meaning "large O") from the short o (Omicron, meaning "small o"). Greek omicron gave rise to the corresponding
Cyrillic letter O and the early Italic letter to
runic ᛟ.
Even alphabets that are not derived from

Semitic most commonly refers to the Semitic languages, a name used since the 1770s to refer to the language family currently present in West Asia, North and East Africa, and Malta.

tend to have similar forms to represent this sound; for example, the creators of the
Afaka and
Ol Chiki scripts, each invented in different parts of the world in the last century, both attributed their vowels for 'O' to the shape of the mouth when making this sound.
Use in writing systems
English
The letter is the fourth
most common letter in the
English alphabet. Like the other English vowel letters, it has associated "long" and "short" pronunciations. The "long" as in ''boat'' is actually most often a
diphthong
A diphthong ( ; , ), also known as a gliding vowel, is a combination of two adjacent vowel sounds within the same syllable. Technically, a diphthong is a vowel with two different targets: that is, the tongue (and/or other parts of the speech o ...
(realized dialectically anywhere from to ). In English there is also a "short" as in ''fox'', , which sounds slightly different in different dialects. In most dialects of
British English, it is either an
open-mid back rounded vowel or an

, it is most commonly an unrounded back to a central vowel .
Common
digraphs include , which represents either or ; or , which typically represents the diphthong , and , , and which represent a variety of pronunciations depending on context and etymology.
In other contexts, especially before a letter with a
minim, may represent the sound , as in 'son' or 'love'. It can also represent the
semivowel as in ''choir'' or ''quinoa.''
In English, the letter in isolation before a noun, usually capitalized, marks the
vocative case, as in the titles to
O Canada or

Other languages

open-mid back rounded vowel ,
mid back rounded vowel or
close-mid back rounded vowel in many languages. Other languages use for various values, usually back vowels which are at least partly open. Derived letters such as and have been created for the alphabets of some languages to distinguish values that were not present in Latin and Greek, particularly rounded front vowels.
