Potential verb complement

 Other terminology: PVC, 可 能 补 语

1. What are potential complements?

Potential complements are used to express two types of ability: the ability to achieve an action; and the ability to move something in a certain direction. Most resultative (apart from 错) and directional verb complements can be turned into potential verb complements by putting 得 (affirmative) or 不 (negative) between the verb and its complement, as shown in the following patterns.

A resultative complement can be placed after 得 to indicate ability to achieve. A directional complement can be placed after 得 to indicate ability to move something in a certain direction.

  main v                                                          得 (affirm.)                                                r./d. complement                

To be able to finish (writing).

To be able to drive (a car) in (to the garage).

main v.                                                         不 (neg.)                                                    r./d. complement

To be unable to finish (writing).

To be unable to drive (a car) in (to the garage).         

2. Are there any PVC  which are only used idiomatically?

There are many idiomatic expressions using potential verb complements which

stand on their own and can't be turned back into resultative or directional verb complements.

3. How can I form a sentence with potential complements?

1.  The object of a sentence is either placed at the beginning of sentence:

(complex)       o.                                          s.                                 v. +  potential complement

I can't understand the words (he has written).

or after the potential complement;

 s.                                   v. +  potential complement                    (complex)      o.

I can't understand the words (he has written).

4. Can I use the particle 了 for completed action in a sentence which has a potential complement?

The particle 了 for completed action is not used, but 了 can be placed at the end of a sentence to indicate a change of situation.

tā  xiĕ          de    liăo   hàn  zì               le

他 写      得  了   汉  字         了

HE  WRITE  DE COPE  CHARACTERS LE

He can write Chinese characters now.

5. How do you differentiate complements of degree (得 construction) from potential complements?

Sometimes one may confuse affirmative potential verb complements with the 得 (complement of degree) construction. In this case, 很 or other adverbs are added before the main adverb of the sentence to show the sentence is a complement of degree construction.

a. (Potential verb complement)

hànzì                 tā  xiĕ       de  hăo,         yīngwén  tā  xiĕ        bu hăo

汉 字          他 写    得 好,       英 文    他写      不好.  

CHARACTERS HE  WRITE DE  WELL,  ENGLISH  HE WRITE BU WELL

He can write Chinese characters well, but not English.

b. (Complement of degree)

hànzì                  tā  xiĕ        de    hĕn     hăo.

汉字            他  写    得   很    好

CHARACTERS   HE  WRITE DE (VERY) WELL

He writes characters (very) well.

6. Are 能 constructions and potential verb complements interchangeable?

Apart from fixed idiomatic expressions, most potential complements can be turned into a 能 sentence with a resultative or directional verb complement.

chī      bu wán         /      bù  néng  chī wán

吃    不 完        /     不  能   吃  完.

EAT   BU FINISH     /       NOT CAN  EAT FINISH

Can't finish eating it.

But one can't turn:

看   不 起

LOOK BU UP

To look down on (sb.) into   Ｘ不能看起Ｘ
