Definitely Mr.Bruce. The more we know the language, the more we know about the cultures around the world. There are many things when we know the language. 

Thank you for your discussion.

  It depends upon the depth of the knowledge and the way it is taught Tulum.

  A student can learn a language,  but learn few ideas.  In that case, they will not  have the full power of the language available to them.

  If ideas are included in the    study,  the student  gains the benefit of understanding ideas.

As the proverbialism goes;  "Knowledge is Power."
