Nature of language learning.

Studying grammar can slow down our progress in English significantly. Basic grammar is a necessity, but focusing on grammar will prevent students from being able to speak English fluently in a reasonable time frame. Grammar is most effective to those who have a solid foundation in English fluency. People learned to speak before they learned grammar. We have to focus on our speaking and listening skills prior to studying grammar. After being able to speak English fluently, we will realize how much easier grammar is.
