Circumflex Information

The circumflex ( ˆ ) is a diacritic used in the written forms of many languages, and is also commonly used in various romanization and transcription schemes. It received its English name from Latin circumflexus (bent around)—a translation of the Greek περισπωμένη (perispōménē).

In the ASCII character encoding, there is a similar but larger character (^) which is often referred to as caret but in Unicode as circumflex accent (U+005E), although it is generally unsuitable for use as a diacritic. Another special circumflex character in Unicode is the smaller modifier letter (U+02C6), mainly intended to be used in phonetic notations. For actually adding the diacritic to a base letter, Unicode also has the circumflex as a combining character (U+0302). In addition, the ISO-8859-1 character encoding includes the precomposed characters â, ê, î, ô, û (as well as their respective capital forms), and dozens of more are available in Unicode.

Uses

Pitch

In the polytonic orthography of Ancient Greek, the circumflex marked long vowels that were pronounced with high and then falling pitch. Its shape was originally a combination of the acute and grave accents (^), but later a variant similar to the tilde (~) was also used.

The circumflex marked a syllable contracted from two vowels: an acute-accented vowel and a non-accented vowel. Because all non-accented syllables were once marked with a grave accent, the contracted syllable was marked by the acute and grave combined. This combination became the circumflex.

The term is also used to describe similar tonal accents that result from combining two vowels in related languages such as Sanskrit and Latin.

Since Modern Greek has a stress accent instead of a pitch accent, the circumflex has been replaced with an acute accent in the modern monotonic orthography.

In Croatian and Serbian, the circumflex is mostly found above the letter a to distinguish homophones. This indicates a falling pitch, albeit less vital than other tonal languages. Examples include sam (am) versus sâm (alone). Thus the correct translation of "I am alone" is Ja sam sâm. Another example: da (yes), dâ (gives).

Length

The circumflex accent marks a long vowel in the orthography or transliteration of several languages.

• Akkadian. In the transliteration of this language, the circumflex indicates a long vowel resulting from an aleph contraction.
• French. In some varieties, such as in Belgian French, vowels with a circumflex are long: fête ("party") is longer than faites.
• Standard Friulian.
• Japanese. In the Kunrei-shiki system of Romanization, and sometimes the Hepburn system, the circumflex is used as a replacement for the macron.
• Jèrriais.
• Turkish. According to Turkish Language Association orthography, düzeltme işareti ("correction mark") over a, i and u marks a long vowel to disambiguate similar words. For example, compare ama (but) and âmâ (blind), şura (that place, there) and şûra (council).^[1] Although official, the required system is complex and younger generations have begun to stop using it.^{[citation needed]}
• Welsh. The circumflex is colloquially known as to bach ("little roof"). It lengthens a vowel (a, e, i, o, u, w, y), and is used particularly to differentiate between homographs; e.g. tan and tân, ffon and ffôn, gem and gêm, cyn and cŷn, or gwn and gŵn.
• In Adûnaic, the Black Speech, and Khuzdûl, constructed languages of J. R. R. Tolkien, all long vowels are transcribed with the circumflex. In Sindarin long vowels in monosyllabic words take the circumflex and long vowels in longer words take the acute.

Stress

The circumflex accent marks the stressed vowel of a word in some languages:

• Portuguese â /ɐ/, ê /e/, and ô /o/ are stressed vowels. May also indicate height (see below).
• Welsh: the circumflex, due to its function as a disambiguating lengthening sign (see above), is used in polysyllabic words with word-final long vowels. The circumflex thus indicates the stressed syllable (which would normally be on the penultimate syllable), since in Welsh, non-stressed vowels may not normally be long. This happens notably where the singular ends in an a, to , e.g. singular camera, drama, opera, sinema → plural camerâu, dramâu, operâu, sinemâu; however, it also occurs in singular nominal forms, e.g. arwyddocâd; in verbal forms, e.g. deffrônt, cryffânt; etc.

Height

The circumflex is also used to indicate the relative height of some vowels:

• In Breton, it is used on an e to show that the letter is pronounced open instead of closed.
• Portuguese â /ɐ/, ê /e/, and ô /o/, are stressed high vowels, in opposition to á /a/, é /ɛ/, and ó /ɔ/ which are stressed low vowels.
• Vietnamese â /ɐ/, ê /e/, and ô /o/ are higher vowels than a /ɑ/, e /ɛ/, and o /ɔ/. The circumflex can appear together with a tone mark on the same vowel, as in the word Việt Nam. Vowels with circumflex are considered separate letters from the base vowels.

Contraction

• In Italian, î is occasionally used in the plural of nouns and adjectives ending with -io [jo] as a crasis mark. Other possible spellings are -ii and obsolete -j or -ij. For example, the plural of vario [ˈvaːrjo] ("various") can be spelt vari, varî, varii; the pronunciation will usually stay [ˈvaːri] with only one [i]. The plural forms of principe /ˈprintʃipe/ ("prince") and of principio /prinˈtʃipjo/ ("principle" or "beginning") can be confusing. principi would be a correct writing of both, with the only difference of the stress being on the first or on the second syllable. In such cases, if the context does not allow disambiguation, it is advised to write the plural of principio as principî or as principii.

Deletion

• In French, it generally marks the former presence of a consonant (usually s) that was deleted and is no longer pronounced. The English forms frequently retain the lost consonant.
  • hôpital (hospital)
  • hôtel (hostel)
  • forêt (forest)
  • rôtir (to roast)
  • côte (coast)
  • pâte (paste)

Some homophones (or near-homophones in some varieties of French) are distinguished by the circumflex, for instance cote ("level", "mark") and côte ("rib" or "coast"). The letter ê is normally pronounced open, like è. In the usual pronunciations of central and northern France, ô is pronounced close, like eau; in Southern France, no distinction is made between close and open o. See also Use of the circumflex in French.

• English: In Britain in the eighteenth century, before the cheap Penny Post and during the time paper was taxed, the combination ough was shortened to ô when the gh was not pronounced, in order to save room in letters: thô for though, thorô for thorough, and brôt for brought.
• In Norwegian, it generally marks the former presence of the letter ð in the spelling of the word – for example, fôr (foðr), vêr (veðr). The ð was replaced by an ordinary d before it disappeared (fodr, vedr).

Semivowel

• In Old Tupi, the circumflex changed a vowel into a semivowel: î was [j], û was [w], and ŷ was [ɰ].

Disambiguation

• In Norwegian, it is used on ô and ê, almost exclusively in the words "fôr" (from Norse fóðr) and the related verb "fôre", meaning "lining" and "to line" (for clothes) or "animal food" and "to feed", to differentiate it from for (the preposition); lêr, meaning "leather" (Norse leðr) and "vêr" (Norse veðr), meaning "weather" or "ram". Both lêr and vêr occur only in the Nynorsk Norwegian; in Bokmål these words are spelled lær and vær.

Letter extension

• In Bulgarian, when transliterated into the Latin alphabet (in systems used prior to 1989), the sound represented in Bulgarian by â, although called a schwa (misleadingly suggesting an unstressed lax sound), is more accurately described as a mid back unrounded vowel /ɤ/. Unlike English or French, but similar to Romanian and Afrikaans, it can be stressed. The Cyrillic letter 'ъ' (er goljam) sometimes is transliterated as 'â' or 'ŭ'; often it is just written as 'a' or 'u'.
• In Chichewa, ŵ denotes the voiced bilabial fricative /β/, hence the name of the country Malaŵi.
• In Esperanto, it is used on ĉ, ĝ, ĥ, ĵ, ŝ. Each indicates a different consonant from the unaccented form, and is considered a separate letter for purposes of collation. See Esperanto orthography.
• In pinyin romanized Mandarin Chinese, the circumflex occurs only on ê, which is used to represent the sound /ɛ/ in isolation. This sound occurs rarely and is only used as an exclamation.
• In Romanian, the circumflex is used on the vowels â and î to mark the vowel /ɨ/, similar to Russian yery. The names of these accented letters are â din a and î din i, respectively. Note: the letter â appears only in the middle of words; thus, its majuscule version appears only in all-capitals inscriptions.
• In Slovak, the circumflex (vokáň) turns the letter o into a diphthong ô /wo/.

Other regular uses

• In Afrikaans, it simply marks a vowel with an irregular pronunciation that is typically stressed. Examples of circumflex use in Afrikaans are sê (to say), wêreld (world), môre (tomorrow) and brûe (bridges).
• In Turkish, the circumflex over a and u is used to indicate when a preceding consonant (k, g, l) is to be pronounced as a palatal plosive; [c], [ɟ] (kâğıt, gâvur, mahkûm, Gülgûn) or alveolar lateral [l] (Elâzığ, Halûk). The circumflex over i is used to indicate a nisba suffix (millî, dinî).^[1]

Exceptional use

• In English the circumflex, like other diacritics, is sometimes retained on loanwords that used it in the original language; for example, rôle.
• In French, m with a circumflex is an informal abbreviation for même, "same," for example in taking notes.
• In Swedish when transcribing dialectal speech, the circumflex is often used to denote an a or o which is pronounced dialectally as if it has been written ä [æ] or ö [ø].

Mathematics

In mathematics, the circumflex is used to modify variable names; it is usually read "hat", e.g. î is "i hat". The Fourier transform of a function ƒ is often denoted by .

In vector notation, it is used to identify unit vectors; for instance î stands for a unit vector in the direction of the x-axis.

In statistics, it is often used for the maximum likelihood estimator of a parameter.
