Which one of the following is NOT true of language learning ?

Language Learning is a result of deliberate and conscious effort for a better understanding of foundational skills of language learning. 

Key Points

It should be noted that:

• Reading is the process of constructing meaning from written texts. Reading is done for comprehending the meaning of the text. 
• It takes time to learn a language, even if it is by acquisition.
• It requires context to learn a language, for example, children speak the language when they have previous knowledge or experience.

Hint

• Grammatical Rules instruct a language user that how language should be used correctly and clearly.
• But it is widely known that effective language learning takes place from practicing it in real context rather than following the accurate rule.

Hence. it could be concluded that Grammatical rules are important for learning a language is NOT true of language learning.
