Sichuanese is a way of speaking used by many people. 
About 120 million people speak it. That is a very large number! It is spoken mostly in Sichuan and Chongqing. It is also used in parts of nearby places like Yunnan and Guizhou. Many different groups use it as a second language.
Sichuanese has many different parts. Some parts sound very different from each other. The Chengdu-Chongqing dialect is spoken in big cities. It is used in local art like Sichuan opera. Some people call this "New Sichuanese." Other parts, like the Minjiang dialect, are called "Old Sichuanese." These parts keep sounds from a very old language called Bashu. The Minjiang dialect can be hard for others to understand.
This way of speaking changed a long time ago. During the Ming dynasty, many people moved to Sichuan. They came from places like Hubei and Hunan. They brought their own words with them. This helped make the Sichuanese we hear today. Some words come from old Chinese. Other words are new. Some even come from English!
Sichuanese is a large group of dialects spoken by about 120 million people. 
Speaking Sichuanese involves many different sounds and tones. There are five main tones used in these dialects. These are the dark level, light level, rising, departing, and entering tones. Some dialects, like the Minjiang dialect, keep the entering tone. Other dialects merge that tone into different ones. For example, the Chengdu-Chongqing dialect merges it into the light level tone. The Chengdu dialect is very important for local culture. It is the main way people perform Sichuan opera. This dialect is often called the most representative of the region.

There are four main sub-dialects to know. The first is the Chengdu-Chongqing dialect. People call this "New Sichuanese" because it has fewer old traits. The second is the Minjiang dialect. This is often called "Old Sichuanese." It keeps sounds from an extinct language called Bashu. The third is the Renshou-Fushun dialect. This one merges the entering tone into the departing tone. The fourth is the Ya'an–Shimian dialect. This one merges that tone into the dark level tone. Each group has its own unique way of sounding.

Sichuanese, also known as Sichuanese Mandarin, is a major branch of Southwestern Mandarin. It is spoken primarily in the Sichuan Basin, which covers most of Sichuan Province and the Chongqing Municipality. 
The structure of Sichuanese is defined by its unique phonology, which includes sounds and tones. There are five phonemic tones: the dark level tone, light level tone, rising tone, departing tone, and the entering tone (also called the checked tone). The tone contours differ significantly from Beijing Mandarin. For example, the second tone in Sichuanese is a low falling tone, while in Beijing, it is different. The fifth tone, the entering tone, is preserved in some areas but merged in others. In 48 of the 150 Sichuanese-speaking cities and counties, the checked tone remains distinct. In the other 102 locations, it has merged into different tones.
Linguists divide Sichuanese into four distinct sub-dialects based on how they treat the checked tone. The Minjiang dialect is notable because it preserves the checked tone. The Chengdu–Chongqing dialect merges this tone into the light level tone. The Renshou–Fushun dialect merges it into the departing tone. Finally, the Ya'an–Shimian dialect merges it into the dark level tone. These sub-dialects are often categorized by their age and heritage. The Minjiang, Ya'an–Shimian, and Renshou–Fushun dialects are spoken in South and West Sichuan. These regions have more inhabitants with indigenous Sichuanese descent. Consequently, these are often called "Old Sichuanese" because they retain characteristics of Bashu, an extinct language.
The Chengdu–Chongqing dialect is spoken in North and East Sichuan and is often called "New Sichuanese." This is because it exhibits fewer characteristics of the ancient Bashu language. The Chengdu dialect is particularly important as the most representative of Southwestern Mandarin. It is widely used in regional art forms, such as Sichuan opera. The dialect's evolution is tied to massive shifts in human history. During the thirteenth century, the population of Sichuan dropped due to plagues and Mongol invasions. This created a vacuum that was eventually filled by waves of migration.
During the Ming dynasty (1368–1644), a great wave of immigration changed the linguistic landscape. Immigrants from Hunan, Hubei, Jiangxi, and Guangdong flooded into the region. They brought their own languages, which eventually supplanted earlier varieties. This mixture of immigrant languages and the existing Ba-Shu substratum created the modern Sichuanese. This history explains why Sichuanese is so distinct within the Mandarin dialect continuum. The vocabulary reflects these diverse origins, drawing from Ba-Shu, Middle Chinese, and immigrant languages. Today, new words also emerge from standard Mandarin and English.
Sichuanese is quite divergent from the Beijing dialect used for Standard Chinese. Only 47.8% of Sichuanese vocabulary is shared with the Beijing dialect. The language also features a system of literary and colloquial readings. This means a single character might have two different pronunciations. The colloquial readings often resemble the older Ba-Shu Chinese. In contrast, the literary readings tend to align more closely with modern standard Mandarin. This dual system is a common feature in other Sinitic varieties like Cantonese or Hokkien.
Beyond its formal structure, Sichuanese is a living, evolving language. In large cities like Chengdu and Chongqing, new words develop and spread rapidly. Some unique terms are exclusive to the region, such as "pa er duo," which describes a henpecked husband. Others, like "xiong2qi3," mean "to cheer someone on" in a way that differs from standard Mandarin. These specific cultural expressions show how the dialect remains a vital part of local identity. It connects the modern inhabitants of the Sichuan Basin to a complex history of migration, art, and ancient traditions.
