Do you think studying the grammar of a foreign language helps you to speak it?

I think grammar is very important when  people want to learn another languages, because the grammar is the base to know a lot of vocabulary structure of sentences and some phrases. This is a principal technique that the people starting to use a foreign language, because when people want to speak with another person they remember of vocabulary and start to form sentences.

However, It´s very important to practice,for example  speaking not only writing, because, the people have more fluency.

 If we don´t study you don´t grammar is more difficult  to understand other people because you don´t have the bases when you want to remember the meaning of some words.

I think grammar is very very important for many people learning another languages.
