Shanghainese vs Mandarin: what’s actually different

They are written with the same characters, and most of those characters mean the same thing. Spoken aloud they are two different languages, and the differences sit exactly where a learner meets them first.

The short answer

Shanghainese is a variety of Wu Chinese, the language of Shanghai and the region around it. Mandarin is the national standard taught in every Chinese school. The two share a script, a great deal of vocabulary and a literary tradition, but a Mandarin speaker who has never learned Shanghainese cannot follow it in conversation. What separates them is not an accent. It is the commonest words, the sound system, the way tone works, and a handful of grammatical words.

The commonest words are the ones that differ

Most characters mean the same thing in both languages: 人 nyin ‘person’ is a person and 水 syu ‘water’ is water. That makes the two look closer than they are, because the words that do differ are the ones in almost every sentence: the pronouns, the word for not, the question particle, and the verbs for saying, knowing and sleeping.

In the 8,269 pairs of parallel sentences behind Verbavia’s Shanghainese course, each saying the same thing in both languages, about 43% of the characters differ. These are some of the words responsible:

A longer list, fifty everyday words with a recording of each in both languages, is on 50 words that differ in Shanghainese and Mandarin.

Put a few of them together and a sentence changes almost completely, while meaning exactly the same thing:

• 我勿晓得。 ngu veh shiau teh ‘I don’t know’, in Mandarin 我不知道。 wǒ bù zhīdào
• 阿拉侪去。 a la ze chi ‘we’re all going’, in Mandarin 我们都去。 wǒmen dōu qù
• 伊垃拉上海。 yi laeh la zaon he ‘he’s in Shanghai’, in Mandarin 他在上海。 tā zài Shànghǎi

That gives a quick test for anything you read. A sentence containing 你 nǐ, 不 bù, 的 de or 吗 ma is almost certainly Mandarin, however Shanghainese the rest of it looks.

The same character, a different sound

Even where the two languages use the same word, they do not say it the same way.

Two differences account for a lot of this. The first is voicing. Shanghainese still separates voiced consonants such as b, d, g, v and z from voiceless ones, a contrast Mandarin lost long ago, so 是 zy ‘to be’ begins with a voiced z where Mandarin shì has none. The second is the glottal stop. Syllables such as 一 ih ‘one’ and 学 ghoh ‘to study’ end abruptly with a catch in the throat, a remnant of the old ‘entering tone’ that Mandarin no longer has. In the romanisation used here, that catch is written -h.

Tone works differently

Both languages are tonal, but they use tone in opposite ways. Mandarin has four tones and a neutral tone, and apart from a few well-known rules a syllable keeps its tone inside a word, which is why Mandarin learners practise tones syllable by syllable. Shanghainese has five tones, but in running speech the first syllable of a word sets the melody for the whole word and the syllables after it lose their own. Shanghainese tones and tone sandhi explains how that works.

A few pieces of grammar

Most of the grammar will feel familiar to a Mandarin speaker. The basic word order is the same, and neither language has verb endings or grammatical gender. The differences are in the small words and in a few habits:

• A yes-or-no question ends with 伐 va: 侬晓得伐 non shiau teh va ‘do you know?’
• 拿 'ne brings the object before the verb, where Mandarin uses 把 bǎ: 拿门锁好。 'ne men su hau ‘lock the door’
• 拨 peh means to give and also marks the passive, covering Mandarin 给 gěi and 被 bèi: 我拨伊一本书。 ngu peh yi ih pen syu ‘I gave him a book’ and 伊拨人骂。 yi peh nyin mo ‘he got told off’
• 老 lau before an adjective means very: 老好 lau hau ‘very good’, where Mandarin says 很好 hěn hǎo
• Shanghainese is comfortable putting the object before the verb, as in the greeting 侬饭吃过伐？ non vae chih ku va ‘have you eaten?’

Can a Mandarin speaker understand Shanghainese?

In speech, mostly not; in writing, often. When Tang Chaoju and Vincent van Heuven tested fifteen Chinese varieties in 2009, listeners from Beijing understood only 5% of sentences in Suzhou Wu, Shanghainese’s close neighbour, while Suzhou listeners understood 87% of Beijing sentences, because everyone in China learns Mandarin at school. The full answer, with what a Mandarin reader can follow on the page, is on its own page: can Mandarin speakers understand Shanghainese?

What this means if you are learning

If you already speak Mandarin, you start with the characters and much of the vocabulary, but your pronunciation habits will get in the way, and the commonest words have to be unlearned and replaced. If you are starting from nothing, you learn the characters and the Shanghainese sounds together, with no second set of pronunciations to untangle.

Either way, Shanghainese cannot be learned from Mandarin materials. The characters will look right and the language will be wrong.
