O-Javanese spelling

O-Javanese, O-Jawa or O-Spelling is a phenomenon that is caused by contradiction between standard Javanese spelling and standard Indonesian spelling (EYD). In standard Indonesian spelling word "a" can only pronounced /a/, while in standard Javanese spelling word "a" have two tone, i.e. /a/ and /ɔ/. in consequence, the Indonesian words that borrowed from Javanese that have syntax "a" on its writings usually pronounced /a/ although in Javanese its pronounced /ɔ/. Hence, the words "a" that pronounced /o/ become written as "o" to simplify for readers that are not from Javanese background.

For example:

This O-Javanese spelling is applied to most standard Javanese in several Javanese dialects such as Blora, Kedu, Madiun, Eastern Northern-coast, Pekalongan, Semarangan, Arekan, Mataram, Tenggerese and Osing. But O-Javanese spelling is not applied and the usages are very rare in the vocabulary of Banyumasan, Western Northern-coast, Bantenese, Dermayon, and Cirebonese.
