At its core, the frequency adverb 常常 expresses that an action or state occurs regularly or repeatedly, but its meaning can shift subtly depending on context and mastering its use can present challenges for learners.
Common errors
1. Incorrect position
1.1 Learners might place 常常 after the verb:
*他们去常常中国。
*他们去中国常常。
他们常常去中国。
*他們去常常中國。
*他們去中國常常。
他們常常去中國。
1.2 Time phrases, like ‘today’, ‘in the morning’, ‘at five o’clock’ can come both before and after the subject. 常常 also indicates ‘when’ something happens and learners might mistakenly place 常常 before the subject. But as a true adverbial 常常 consistently follows the subject and precedes the verb:
*常常他们去中国。
他们常常去中国。
*常常他們去中國。
他們常常去中國。
2. Forgetting the adverb 很
In affirmative sentences with an adjective predicate, leaners might forget 很 before the adjective:
*我常常忙。
我常常很忙。
*我常常忙。
我常常很忙。
3. Using 常常 for non-recurring actions or permanent states
常常 is used only for repeatable actions or states. Learners might mistakenly use 常常 for non-recurring actions or permanent states:
*他常常很高。
他很高。
*他常常很高。
他很高。
*我常常是学生。
我是学生。
*我常常是學生。
我是學生。
*他常常去中国一次。
他去中国一次。
*他常常去中國一次。
他去中國一次。
4. Uncertainty about where to place 不
Dependent on the intended meaning, the negation adverb 不 can appear both before and after 常. This might be confusing for learners.
不常 negates 常, the frequency and not the verb. It implies that something rarely happens:
他不常吃早饭。
他不常吃早飯。
常 modifies 不, the negation, emphasizing repeated failure. It indicates habitual neglect with an implied criticism:
他常不吃早饭。
他常不吃早飯。
5. Confusing 常常 and 经常/經常
Both 常常 and 经常/經常 are adverbs expressing frequency. In many situations they can be used interchangeably, but they also have different functions. This might confuse learners and lead to misusing 常常 in contexts where 经常/經常 fits better.
When talking about future plans 经常/經常 is preferable:
明年我们会经常学习。
明年我們會經常學習。
When talking about impersonal frequency, such as weather or mechanical issues 经常/經常 is preferable. 常常 leans toward human habits:
这儿经常下雨。
這兒經常下雨。
6. Overuse of 常常
Overuse of 常常 in places where it sounds too strong, redundant, or contextually inappropriate, such as with permanent states, one-time events, greeting or negative contexts:
他常常生病。
他常常生病。
This might sound too direct, possibly insensitive or even judgmental.
A more neutral alternative could be:
他有时候生病了。
他有時候生病了。
你常常说错。
你常常說錯。
