Circumflex

The circumflex is a diacritic in the Latin and Greek scripts that is used in the written forms of many languages and in various romanization and transcription schemes. It received its English name from Latin circumflexus 'bent around'—a translation of the Greek περισπωμένη (perispōménē). The circumflex in the Latin script is chevron-shaped ( ˆ ), while the Greek circumflex may be displayed either like a tilde ( ˜ ) or like an inverted breve (   ̑ ).

In English the circumflex, like other diacritics, is sometimes retained on loanwords that used it in the original language (for example, crème brûlée). The diacritic is also used in mathematics, where it is typically called a hat or roof or house. The circumflex has its origins in the polytonic orthography of Ancient Greek, where it marked long vowels that were pronounced with high and then falling pitch. In a similar vein, the circumflex is today used to mark tone contour in the International Phonetic Alphabet. The shape of the circumflex was originally a combination of the acute and grave accents (^), as it marked a syllable contracted from two vowels: an acute-accented vowel and a non-accented vowel (all non-accented syllables in Ancient Greek were once marked with a grave accent). Later a variant similar to the tilde (~) was also used.
