Gan Chinese

Closer than to Mandarin, but distinct. Older classifications grouped Gan and Hakka together because both share preservation of voiceless aspirates and certain phonological patterns. Modern Chinese linguistics generally treats them as separate primary branches. Gan and Hakka speakers can sometimes follow each other better than they can follow Mandarin, but mutual intelligibility is limited without exposure.

Mostly in Jiangxi province (its core), with smaller pockets in eastern Hunan, southeastern Hubei, and western Fujian and Anhui. Nanchang Gan is often treated as the prestige variety. The boundaries with Mandarin to the north, Wu to the east, Min to the south, and Hakka to the southeast make Jiangxi a transitional Sinitic area.

Six tones in most varieties, though the inventory and contour shapes vary across subdialects. Gan also has tone sandhi rules that adjust tones in connected speech, similar to other southern Sinitic languages. The exact tone count for any given speaker depends on regional sub-variety.

Under typical pressure from Mandarin like most non-Mandarin Sinitic languages. National education and broadcasting use Mandarin, and younger urban Jiangxi residents in Nanchang increasingly use Mandarin in inter-regional contexts. Rural Gan transmission remains stronger, and the language is far from immediately endangered, but younger generations show signs of language shift.

Most written Gan uses Han characters, sharing the Chinese writing system, but with some dialect-specific characters and many words for which there's no standard written form. Most Jiangxi publishing uses Standard Written Chinese (which follows Mandarin grammar and vocabulary even when readers pronounce it in Gan). Informal social media and scripted dialogue are the main contexts where written Gan appears.
