Is 马克又会汉语又会日语 an error in my Chinese book? Isn't 会汉语 incorrect? This is an example from my Chinese textbook:



I transcribe it below:


  例如：
  Lìrú:
  丁波的姐姐又高又漂亮
  Dīngbō de jiějiě yòu gāo yòu piàoliang
  马克又会汉语又会日语
  Mǎkè yòu huì hànyǔ yòu huì rìyǔ


The second sentence takes me by surprise; it looks like an error to me.  I think 会汉语 (huì hànyǔ; "can Chinese") should be 会说汉语 (huì shuō hànyǔ; "can speak Chinese") or a variant like 会讲汉语.

Question: Is 马克又会汉语又会日语 an error in my Chinese book?
会 here is a verb meaning to know.
Here are two sample sentences from A Chinese-English Dictionary:

他还会两出京戏。
Tā hái huì liǎng chū Jīngxì.
He knows a few airs of Beijing opera.



我会英语, 不会日语。
Wǒ huì Yīngyǔ, bù huì Rìyǔ.
I know English but not Japanese.

ABC dictionary defines it as to understand or to grasp

你会吗?
Nǐ huì ma?
Do you know how?
