Wu Chinese grammar, step by step

The five tones split into two registers (Yin = high-register, Yang = low-register) determined automatically by the initial consonant: voiceless consonants → Yin, voiced consonants → Yang. Tones 4 and 5 are "entering tones" (入声 rùshēng) — short, checked syllables ending in a glottal stop — preserved in Wu but lost in Mandarin centuries ago.

Like all Sinitic languages, Wu has zero verb inflection. The same form of 讲 (goeq4) serves for I / you / she / we / they, present / past / future. Person, number, and tense are marked by separate words and particles — never by changing the verb itself.

Wu Chinese follows Subject–Verb–Object order, the same as English and Mandarin. "I speak Wu Chinese" maps directly: 我 (I) 讲 (speak) 吴语 (Wu Chinese). This familiar skeleton makes basic sentences easy to build — particles and aspect markers fill in the grammatical details.

Wu Chinese requires a classifier (measure word) between a number or demonstrative and a noun. You cannot say *一书 directly. The most general classifier is 个 (geq4). Specific nouns take their own classifiers: 本 (ben2) for books, 张 (zang1) for flat things. Demonstratives (这/那, ze3/na3 in Wu) also need a classifier.

脱 (teq4) is Wu Chinese's primary completive aspect marker — placed directly after the verb to signal the action reached its endpoint. It is functionally similar to Mandarin 了 after a verb, but 脱 is specific to Wu and sounds different. Without 脱 the action is simply stated; with 脱 it is marked as done.

辣 (la5) marks a progressive or durative action — something happening right now or still ongoing. It sits after the verb (or at the end of the clause). The verb itself does not change. 辣 is Wu-specific; Mandarin uses 着 (zhe) for a similar purpose, but 辣 sounds and behaves differently.

覅 (fiau3) means "don't" — it combines negation and prohibition into one word used for imperatives or "please don't". 勿 (veq5) is the general declarative negator equivalent to Mandarin 不: it negates verbs and adjectives in statements. Neither 覅 nor 勿 is used in Mandarin — they are distinctly Wu.

In Wu Chinese, 是 (zii3) links a subject to a noun or identity. Adjectives in Wu function as stative verbs — they make a predicate on their own without a linking word. "好吃" (hau2ceq4, delicious) simply follows the subject: 搿个菜好吃 (This dish is delicious). Adding 是 before an adjective is ungrammatical.

Wu Chinese forms polar questions by placing the verb, then 勿 (veq5, "not"), then the verb again: "V-勿-V?" means "V or not V?" — equivalent to "are you V-ing?" The listener answers by saying the verb (yes) or 勿 + verb (no). A sentence-final question particle can also be added instead.

Wu Chinese has sentence-final particles (SFPs) that signal attitude, tense-relevance, and discourse function. Three important ones: 𠲎/伐 (va, a general yes/no question marker), 哉 (ze, marks a new or changed situation — like "now/already"), 嗲 (dia, marks something as cute or charming, unique to Wu). These are entirely distinct from Mandarin's particles.

Entering tones (入声 rùshēng) are syllables that close with a glottal stop (/ʔ/), making them short and abrupt. Mandarin lost them centuries ago, collapsing entering-tone syllables into regular tones. Wu preserved them — meaning Wu speakers make distinctions that Mandarin cannot. This is one reason Wu feels so different even to Mandarin speakers. In Wugniu romanization, entering-tone syllables end in -q (Tone 4) or another stop (Tone 5).

Wu Chinese is left-dominant: the first syllable of a phrase "sets" the overall pitch contour, and all subsequent syllables fall into a predictable high or low pattern regardless of their underlying tones. This is radically different from Mandarin, where each syllable keeps its tone. In practice: learn the tone of the first syllable and the rule takes care of the rest within the same phrase.

Wu Chinese, like other Sinitic varieties, is topic-prominent. Any noun phrase can be fronted as the "topic" — what the sentence is about. The rest of the sentence is the "comment" about it. Topic-comment sentences are used to shift focus, introduce contrast, or set the scene. The topic is often followed by a short pause.

Wu chains verbs directly without conjunctions or prepositions. The sequence of verbs mirrors the sequence of actions: the first verb is often motion or means; the second is the purpose or result. This is the same pattern as Mandarin, but with Wu-specific vocabulary and particles. No "and", "in order to", or "by" is needed — word order does the job.

Wu Chinese grammar is a layered system: tones identify words, aspect particles mark the phase of an action, Wu-specific negators replace Mandarin words, and topic-comment structure shifts focus — all without a single verb conjugation. Once you can read those layers together, you are reading Wu Chinese.
