Chinatown Chinese: new vocabulary versus a distinct dialect

Could a community develop its own way of speaking? Sure. People living in San Francisco encounter places, holidays, and experiences that people in China may never have encountered. It makes sense that they would develop words for those things. Think of the mixing of Spanish and English: contact with another language can affect how people speak. But that makes the linguists' proposal worth considering; it doesn't establish that Chinatown Chinese is a distinct dialect.

The opening gives two claims supporting that proposal. First, a newcomer from China supposedly has trouble communicating with a local Chinese American who nominally speaks the same language. Second, local Chinese Americans supposedly can communicate across traditional dialects if they know the shared Chinese-American vocabulary.

Keep the people straight. The first claim puts a barrier between newcomers and local speakers. The second puts a bridge between local speakers from different dialect backgrounds. These aren't opposite claims about the same pair of people. The rest of the argument will test each one.

Start with that supposed barrier. A newcomer might not know a name for a San Francisco landmark or an American holiday. Why would they? They haven't lived there. But needing an explanation of a local name isn't the same as being unable to understand someone's language. Think of hearing a nickname for a neighborhood or highway in another town. Someone explains what it refers to, and the conversation continues.

We get two examples of how local terms develop. Dang-tang carries over the sound of downtown. Gong-ngihn ngiht translates labor plus day to name Labor Day. Sound borrowing and direct translation are different processes, but both add vocabulary for the community's experiences.

The crucial distinction is “supplemented, but not supplanted.” The new words add to the traditional language; they don't replace its core. Speakers who share a traditional dialect can converse fairly readily. A local term can be explained, avoided, or understood from context. So the first claimed barrier largely disappears when we look at what the unfamiliar vocabulary actually does.

Now test the claimed bridge. Does knowing the same local words let people understand one another regardless of their underlying dialect? Not necessarily. Some speakers have become familiar with Cantonese by watching movies or hearing it spoken. That exposure helps explain their understanding without establishing that they all share a new dialect.

More importantly, differences in sounds, grammar, and vocabulary persist. Knowing the same name for an American street doesn't teach you the rest of another person's dialect. The shared local terms make up only a small, peripheral part of the language. They cannot guarantee that everything else becomes understandable.

We aren't handed a final sentence announcing the main point, but the argument has made it clear. The first supporting claim exaggerates the difficulty of communicating within the same traditional dialect. The second exaggerates the ease of communicating across different dialects. Neither establishes the distinct Chinatown dialect that the linguists propose.

Notice that this conclusion doesn't deny the existence of new words. We accept those additions and question what they prove. That's why “there are unfamiliar local terms” and “there is a distinct new dialect” cannot be treated as the same claim.
