Control or guidance especially by an individual, group, or system.
When taking this look at the word, immediately I think of a teacher/mentor, or in my case a foreign language teacher. As teachers, we have the majority of control in our students' language learning. Sure, students can seek out other means to learn a language (books, movies, music, etc); however, instruction in a classroom is (hopefully) the most accurate way to learn a language. As teachers, we fit all three categories of this guidance and control. We have individual times with all students both in and out of the class. As a whole, we work as a group to ensure the language learning as a department. Finally, all languages come together as a system to enrich and enlighten the students to the world I which they live.
Another way of looking at this word with language would be a native speaker from any country respectively. To a foreigner, they are your guide to experiencing the language and culture from that country. I know what I have done before with friends that are native speakers from other countries, we both help each other out when needed to remember words or learn new terms. For me at least, it's fun and exciting to be opened up to a new world. Without this guide or control, this task would be much harder to accomplish. Now my question is, have any of you found yourself in either of these scenarios?
