When communicating in Chinese you may often make mistakes using Chinese grammar like:

False:

    我喜欢说汉语，但是我只说一点儿。

     Wǒ xǐhuɑn shuō hànyǔ, dànshì wǒ zhǐ shuō yìdián’ér 。

True:

    我喜欢说汉语，但是我只会说一点儿。

    Wǒ xǐhuɑn shuō hànyǔ, dànshì wǒ zhǐ huì shuō yìdián’ér 

 

“一点儿”表明通过学习、时间获得和掌握的汉语知识和能力极为有限，通常应在第二个谓语动词“说”的前边加“会”。

一点儿 is used here to indicate that one’s knowledge and competence in the Chinese language acquired through learning and practice is rather limited. 会 is needed before the second predicate verb 说.
