Ĵ

Template:Short description Template:One source Template:Infobox grapheme Template:Esperanto sidebar Ĵ or ĵ (J circumflex) is a letter in Esperanto orthography representing the sound Template:IPAblink.

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 used in the Persian Latin (Rumi) alphabet, equivalent to ژ.
