Ĵ

Ĵ or ĵ (J circumflex) is a letter in Esperanto orthography representing the sound [ʒ].

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 letter j to better preserve the shape of borrowings from that language (such as ĵurnalo from journal) than Slavic ž would.

Where type with diacritics is not available, L. L. Zamenhof allowed its substitution by jh. Recently, the use of jx instead of ĵ has also become popular; see x-convention.
