(Redirected from J-circumflex)
Latin letter J with circumflex; used in Esperanto
While Esperanto orthography uses a diacritic for its four postalveolar consonants, as do the Latin-based Slavic alphabets, the base letters are Romano-Germanic. Ĵ is based on the French pronunciation of the letter j to better preserve the shape of borrowings from that language (such as ĵurnalo from journal) than Slavic ž would.
Ĵ is the fourteenth letter in Esperanto orthography. Although it is written as jx and jh respectively in the x-system and h-system workarounds, it is normally written as J with a circumflex: ĵ.
Ĵ is used in the Persian Latin (Rumi) alphabet, equivalent to ژ.
Usage
In mathematics
The letter ĵ is often used to denote a unit vector in mathematics and physics for representing y-vector.
