Potential Complements (得/唔) in Cantonese

In Brief

Cantonese puts 得 dak1 or 唔 m4 between a verb and its result complement to show whether that result is achievable: 睇得明 tai2 dak1 ming4 means “can understand by reading,” while 睇唔明 tai2 m4 ming4 means “cannot understand.” The construction describes successful or unsuccessful attainment of a particular result, so it is more precise than simply translating English “can” or “can’t.”

Overview

A complement is an element that completes a verb’s meaning. A resultative complement (a word after the verb that names its outcome) tells you what the action achieves. For example, 睇完 tai2 jyun4 is “finish reading or watching”: 睇 names the activity and 完 names the result. Similarly, 聽到 teng1 dou2 says that listening reaches the result of actually hearing something.

Potential complements take this result structure one step further. They say whether the result can be reached under the circumstances. Put 得 dak1 between the action and the result for a positive possibility; replace it with 唔 m4 for a negative possibility. This is a core B1 pattern because it lets you speak naturally about understanding, perceiving, finishing, finding, carrying, fitting, eating, and many other everyday outcomes.

English encourages learners to begin with “can” and then choose a verb. Cantonese often frames the same situation around the intended result. “I can read Chinese” might concern learned ability, but “I can understand this Chinese notice by reading it” is about a successful result. The second meaning is exactly where 睇得明 belongs.

How It Works

The basic pattern

Meaning	Structure	Example	Literal logic
the result is achievable	verb + 得 + result complement	睇得明	look/read + possible + understand
the result is not achievable	verb + 唔 + result complement	睇唔明	look/read + not possible + understand

Here V means the action verb and RC means the result complement:

• V-得-RC: can achieve the result
• V-唔-RC: cannot achieve the result

The two forms are a matched pair. 唔 occupies the same internal position as 得; it does not normally sit before the whole positive potential phrase.

Common result complements

Complement	Result expressed	Positive potential	Negative potential
到 dou2	reach, obtain, or perceive successfully	聽得到 teng1 dak1 dou2	聽唔到 teng1 m4 dou2
完 jyun4	finish	做得完 zou6 dak1 jyun4	做唔完 zou6 m4 jyun4
明 ming4	understand	睇得明 tai2 dak1 ming4	睇唔明 tai2 m4 ming4
清楚 cing1 co2	clearly	聽得清楚 teng1 dak1 cing1 co2	聽唔清楚 teng1 m4 cing1 co2
見 gin3	come into sight	睇得見 tai2 dak1 gin3	睇唔見 tai2 m4 gin3
落 lok6	go down	食得落 sik6 dak1 lok6	食唔落 sik6 m4 lok6
起 hei2	rise or be lifted	拎得起 ling1 dak1 hei2	拎唔起 ling1 m4 hei2
入 jap6	enter or fit in	放得入 fong3 dak1 jap6	放唔入 fong3 m4 jap6

The English translation changes with the complement. 食唔落 is literally about food not “going down,” but naturally it often means “cannot eat” because the person is full, ill, upset, or has no appetite. 放唔入 means that putting something inside cannot achieve the result, often because there is not enough space.

Adding a subject and an object

Cantonese frequently leaves out a subject when it is obvious. A full sentence can nevertheless follow the familiar order:

subject + V-得/唔-RC + object

• 我睇得明呢篇文章。 “I can understand this article.”
• 佢搬唔郁張枱。 “They cannot move the table.”

An object is the person or thing affected by the action. With a short object, placing it after the potential unit is common. Longer or contrastive objects may be introduced earlier as the topic:

• 呢篇文章，我睇得明。 “This article, I can understand.”
• 咁多功課，我今晚做唔完。 “This much homework, I can’t finish tonight.”

This topic-first order is especially useful when a heavy object would make the end of the sentence awkward.

Asking questions

A statement can become a yes–no question through intonation and a sentence-final particle:

• 你睇得明呢本書？ “Can you understand this book?”
• 你聽得到嗎？ “Can you hear?”

A common conversational alternative uses an A-not-A question (a choice between positive and negative forms):

• 你睇唔睇得明？ “Can you understand it or not?”
• 你食唔食得落？ “Can you manage to eat it?”

The answer can repeat the relevant potential phrase: 睇得明 “I can understand it” or 睇唔明 “I can’t understand it.”

Potential complements versus 可以 and 識

All three may become English “can,” but they answer different questions.

Form	Main focus	Example	Natural meaning
可以 ho2 ji5	permission or general possibility	呢度可以影相。	You may/can take photos here.
識 sik1	learned knowledge or skill	我識游水。	I know how to swim.
V-得/唔-RC	whether a specific result is attainable	我今日游得到對面。	I can reach the other side by swimming today.

Compare 我識睇中文 “I can read Chinese / know how to read Chinese” with 我睇得明呢封信 “I can understand this letter by reading it.” The first describes acquired ability; the second evaluates the result in a particular case. Context can blur these categories, but this distinction is a reliable starting point.

Examples in Context

Cantonese	Jyutping	English	Note
我食得落。	ngo5 sik6 dak1 lok6.	I can manage to eat it.	The food can “go down.”
我今日冇胃口，食唔落。	ngo5 gam1 jat6 mou5 wai6 hau2, sik6 m4 lok6.	I have no appetite today, so I can’t eat.	A common reason for 食唔落.
太細聲喇，我聽唔到。	taai3 sai3 seng1 laa3, ngo5 teng1 m4 dou2.	It’s too quiet; I can’t hear it.	到 marks successful perception.
而家聽得到未？	ji4 gaa1 teng1 dak1 dou2 mei6?	Can you hear it now?	未 asks whether the new state has been reached yet.
你睇得明呢本書？	nei5 tai2 dak1 ming4 ni1 bun2 syu1?	Can you understand this book?	明 is the intended result of reading.
啲字太深，我睇唔明。	di1 zi6 taai3 sam1, ngo5 tai2 m4 ming4.	The wording is too difficult; I can’t understand it.	The obstacle is difficulty, not unwillingness to read.
仲有兩個鐘，我做得完。	zung6 jau5 loeng5 go3 zung1, ngo5 zou6 dak1 jyun4.	There are still two hours; I can finish it.	完 focuses on completion.
今日一定做唔完咁多嘢。	gam1 jat6 jat1 ding6 zou6 m4 jyun4 gam3 do1 je5.	I definitely can’t finish this much today.	A limit imposed by time or workload.
呢個箱太重，我拎唔起。	ni1 go3 soeng1 taai3 cung5, ngo5 ling1 m4 hei2.	This box is too heavy; I can’t lift it.	起 gives the result “up.”
呢張相啲字睇得清楚。	ni1 zoeng1 soeng2 di1 zi6 tai2 dak1 cing1 co2.	The writing in this photo can be seen clearly.	清楚 describes a clear result.
個袋太細，部電腦放唔入。	go3 doi2 taai3 sai3, bou6 din6 nou5 fong3 m4 jap6.	The bag is too small; the computer won’t fit inside.	Physical conditions block the result.
你聽唔聽得明佢講乜？	nei5 teng1 m4 teng1 dak1 ming4 keoi5 gong2 mat1?	Can you understand what they’re saying?	A-not-A question form.

Common Mistakes

1. Putting 唔 before the whole positive form

• Wrong: 唔睇得明
• Right: 睇唔明
• Why: In a negative potential complement, 唔 replaces 得 between the action and its result. 唔睇 by itself means “not read/look” and negates the action rather than its attainability.

2. Using the pattern when permission is meant

• Wrong for permission: 我入得去？ when asking “May I go in?”
• Better: 我可唔可以入去？ “May I go in?”
• Why: 可以 is the normal choice for permission. 入得去 instead asks whether entry is practically possible—perhaps the door is open or the route is passable. Context can occasionally make both relevant, but they are not interchangeable by default.

3. Confusing learned skill with a particular outcome

• Unnatural for general skill: 我游得過對面 as the basic way to say “I know how to swim.”
• Right: 我識游水。 “I know how to swim.”
• Potential result: 我游得過對面。 “I can swim across to the other side.”
• Why: 識 presents an acquired skill. A potential complement evaluates whether a named result can be achieved.

4. Forgetting the result word

• Incomplete for this pattern: 我做得。
• Clear potential complement: 我做得完。 “I can finish it.”
• Why: The productive pattern taught here needs a result after 得. Be aware that 得 has other independent uses, so 做得 may occur in other constructions; it is not automatically the positive partner of 做唔完.

5. Treating every 得 after a verb as potential

• Different structure: 佢唱得好好聽。 “They sing very beautifully.”
• Potential structure: 佢今日唱得到。 “They can manage to sing today.”
• Why: In 唱得好好聽, 得 introduces a description of how the singing is performed. In a potential complement, it sits before a result whose attainment is possible. Meaning and the words after 得 identify the construction.

Usage Notes

Potential complements are highly productive in spoken Cantonese. They often imply a practical condition: enough time, sufficient strength, suitable size, audible volume, readable language, appetite, or access. Speakers do not always state that condition because the situation makes it clear. 做唔完 may mean “I can’t finish” because there is too much work or too little time, not because the speaker lacks the skill.

This makes the pattern useful for tactful refusals. 今日做唔完 describes an unattainable result and can sound less blunt than a bare statement of unwillingness. It does not, however, literally mean “I don’t want to do it.” To express unwillingness, say so directly with forms such as 唔想 “do not want to.”

Jyutping writes the potential marker 得 as dak1. The same written character has other grammatical roles, and its interpretation depends on the structure. Written Standard Chinese has related potential-complement patterns, but natural Cantonese vocabulary, pronunciation, particles, and preferred phrasing remain distinct; do not assume that every Mandarin expression transfers unchanged into conversation.

Beyond the Basics / Advanced Use

Potentiality and an achieved event are different viewpoints

A resultative phrase reports an outcome: 我睇完咗本書 means “I finished reading the book.” A potential phrase evaluates attainability: 我今日睇得完本書 means “I can finish reading the book today.” The first presents completion as an event; the second presents it as possible. Avoid adding 咗 mechanically to a potential phrase merely because the English translation concerns the past. If you need to say that you were able to achieve something on a particular occasion, Cantonese often chooses a fuller sentence that reports the actual result and lets context establish the difficulty.

得 has several jobs

Potential 得 must be distinguished from at least two frequent patterns:

Pattern	Function	Example	Meaning
V + 得 + result	attainable result	睇得明	can understand by reading
V + 得 + description	manner or degree	講得好清楚	speak very clearly
得唔得	acceptability or “is it okay?”	聽日先做，得唔得？	Is it okay to do it tomorrow?

These overlap in form but not in function. In 講得好清楚, 好清楚 evaluates the manner or quality of speaking. In 聽得清楚, context may support “can hear clearly,” especially when contrasted with 聽唔清楚. Real speech can therefore contain genuine ambiguity, and the surrounding situation usually resolves it.

The result complement carries much of the meaning

Advanced control comes less from memorising 得 and 唔 than from building a repertoire of natural verb–result combinations. English “can’t” is broad; Cantonese encourages you to select the blocked result:

• 睇唔見 — cannot see it because it does not come into view
• 睇唔明 — can see/read it but cannot understand it
• 睇唔清楚 — can see something, but not clearly
• 睇唔完 — cannot finish reading or watching it

Choosing the complement lets you diagnose the problem precisely. This is one reason literal word-for-word translation from English is unreliable.

Practice Tips

1. Learn positive and negative forms as pairs. For each useful combination, say both forms aloud: 聽得到／聽唔到, 做得完／做唔完, 睇得明／睇唔明. This reinforces the internal slot where 得 and 唔 alternate.
2. Describe the obstacle and then the result. Make short pairs such as 太嘈喇，聽唔清楚 “It’s too noisy; I can’t hear clearly” or 仲有時間，做得完 “There’s still time; I can finish.” The reason helps you feel that the construction concerns attainability.
3. Sort English “can” into three questions. Ask yourself: Is this permission (可以), learned skill (識), or achievement of a result (V-得-RC)? Then build the Cantonese sentence instead of translating “can” directly.
